Distributed, hybrid, and multicloud
1. Introduction
What this service is
Google Distributed Cloud software for bare metal is Google Cloud’s Kubernetes-based platform for running Google-managed software on your own bare metal servers in your data center or edge locations, while integrating with Google Cloud for fleet management, policy, observability, and (optionally) advanced GKE Enterprise features.
Simple explanation (one paragraph)
If you need to run modern containerized apps close to your data (on-premises or at the edge) but still want a consistent Kubernetes experience aligned with Google Cloud, Google Distributed Cloud software for bare metal lets you deploy and operate Kubernetes clusters on your own hardware with Google’s tooling and support.
Technical explanation (one paragraph)
Technically, this is a Kubernetes distribution and lifecycle management toolchain designed for non-virtualized infrastructure. You install clusters onto customer-managed bare metal nodes, connect those clusters to Google Cloud (typically through a Fleet / hub-style control plane), and then manage configuration, policy, upgrades, and observability using Google Cloud-integrated components. You own the physical servers, networking, and day-2 operations for hardware and the local environment; Google provides the software distribution, validated architecture patterns, and support.
What problem it solves
It solves the “hybrid reality” problem: organizations want cloud-native application delivery and governance, but cannot move all workloads to public cloud due to latency, data gravity, sovereignty, regulatory requirements, or dependency on specialized on-prem hardware. Google Distributed Cloud software for bare metal provides a practical route to standardize on Kubernetes and Google Cloud-aligned operations without requiring virtualization.
Naming note (important): Google has evolved its hybrid/on-prem branding over time (for example, “Anthos on bare metal” / “Anthos clusters on bare metal” in earlier eras). The product name requested here—Google Distributed Cloud software for bare metal—should be treated as the primary current name. Always verify the latest naming and feature matrix in official docs before finalizing designs: https://cloud.google.com/distributed-cloud/bare-metal/docs
2. What is Google Distributed Cloud software for bare metal?
Official purpose
Google Distributed Cloud software for bare metal is intended to run Kubernetes clusters on customer-owned bare metal infrastructure while enabling centralized management and consistency with Google Cloud’s hybrid and multicloud approach.
Core capabilities (what it can do)
- Deploy Kubernetes clusters onto bare metal servers in customer locations (data center / edge).
- Provide cluster lifecycle operations (create, upgrade, patching workflows, health checks) using Google-provided tooling.
- Connect clusters to Google Cloud for centralized fleet-style management (inventory, policy, configuration, and observability integration where enabled).
- Support hybrid operating models where some services remain on-prem and others run in Google Cloud.
Major components (conceptual)
Exact component names and packaging can vary by release; verify the “Architecture” and “Concepts” sections in the docs for your version.
- Bare metal nodes: physical servers used for Kubernetes control plane and worker nodes.
- Cluster lifecycle tooling: a Google-provided CLI and workflows used to bootstrap and manage clusters (commonly referenced in documentation and guides).
- Networking stack: CNI, service networking, and load balancing for on-prem networks (often includes a software load balancer approach suited for bare metal).
- Connectivity to Google Cloud: used for registering clusters into a fleet/hub, policy distribution, and (optionally) remote access patterns.
- Observability integration: integration with Google Cloud Operations (Cloud Logging/Monitoring) may be available/configurable depending on edition and deployment mode.
- Security and policy: support for identity, policy enforcement, and auditability consistent with Google Cloud hybrid governance patterns.
Service type
– This is not a “fully managed” hosted control plane in the same way as Google Kubernetes Engine (GKE) in Google Cloud.
– It is a software distribution installed and operated on your infrastructure, usually under a subscription model that includes support and updates.
Scope model (how it’s scoped)
In practice, the software runs in your environment, but it commonly integrates with Google Cloud constructs such as:
- Google Cloud project: for APIs, billing, IAM, and fleet registration.
- Fleet / hub membership: for registering and grouping clusters for centralized governance (terminology can change; verify current naming in docs).
- On-prem site: your local data center/edge network, where you manage IP ranges, routing, DNS/NTP, and hardware.
How it fits into the Google Cloud ecosystem
Google Distributed Cloud software for bare metal is part of Google Cloud’s broader Distributed, hybrid, and multicloud portfolio. It is typically used with:
- IAM for administrative access control to fleet-level features.
- Cloud Logging / Cloud Monitoring for observability (where configured).
- Artifact Registry to store container images used by on-prem clusters.
- Cloud VPN / Cloud Interconnect (optional) for private connectivity patterns between on-prem and Google Cloud.
- Policy and configuration management capabilities commonly associated with GKE Enterprise / Anthos-era feature sets (availability depends on licensing and version—verify feature compatibility).
3. Why use Google Distributed Cloud software for bare metal?
Business reasons
- Data locality and sovereignty: keep sensitive datasets on-prem while modernizing application deployment.
- Edge latency: run workloads close to users/devices in factories, retail sites, telecom edge, or hospitals.
- Cloud transformation without full migration: standardize on Kubernetes operational patterns while legacy systems remain on-prem.
- Vendor-backed support: organizations that want a supported Kubernetes stack for on-prem bare metal (instead of purely self-managed upstream).
Technical reasons
- Bare metal performance: avoid virtualization overhead; useful for high-throughput data processing, packet processing, or hardware-accelerated workloads (GPU/FPGA), subject to driver and Kubernetes integration.
- Consistent Kubernetes platform: align on Kubernetes and Google Cloud ecosystem tooling across on-prem and cloud.
- Hybrid architecture enablement: build services that run partly on-prem and partly in Google Cloud, connected via secure networking.
Operational reasons
- Standardized lifecycle: a repeatable approach to creating/upgrading clusters compared to ad-hoc kubeadm builds.
- Fleet-level governance: register clusters and apply consistent policy/config across multiple sites (capability depends on edition and configuration).
- Observability integration: consolidate metrics/logs into Google Cloud Operations (when enabled), rather than running independent stacks per site.
Security / compliance reasons
- Centralized policy patterns: enforce guardrails with policy-as-code (verify the exact supported policy controllers for your version).
- Auditability: unify audit logs and access models across on-prem and cloud.
- Network control: keep traffic local; design explicit, controlled egress to Google Cloud.
Scalability / performance reasons
- Scale across sites: manage many clusters deployed in multiple on-prem/edge locations.
- Predictable performance: dedicated physical capacity with consistent latency profiles.
- High I/O workloads: pair with local NVMe, SAN/NAS, or specialized networking (verify storage integrations).
When teams should choose it
Choose Google Distributed Cloud software for bare metal when you need:
- Kubernetes on physical servers (not VMware) with Google Cloud alignment.
- Hybrid management and governance (fleet-style) across multiple environments.
- On-prem constraints: data gravity, regulation, latency, or specialized hardware.
When teams should not choose it
Avoid or reconsider if:
- You don’t have strong on-prem operations capabilities (networking, Linux, hardware lifecycle, monitoring).
- You want a fully managed Kubernetes control plane (consider GKE in Google Cloud).
- Your environment is primarily VMware-based and you want a VMware-centric deployment model (verify whether another Google Distributed Cloud variant fits better).
- You cannot meet network/DNS/NTP/IPAM prerequisites consistently across sites.
- You need a small “developer-only” environment without hardware—this service is inherently infrastructure-heavy.
4. Where is Google Distributed Cloud software for bare metal used?
Industries
- Manufacturing: plant-floor applications, near-real-time analytics, OT/IT convergence.
- Telecom: edge compute, low-latency network services (subject to CNF requirements).
- Financial services: regulated data environments, low-latency trading support systems.
- Healthcare: patient data locality, hospital edge apps, medical imaging workflows.
- Retail: in-store systems, inventory, local personalization, video analytics.
- Public sector: sovereignty requirements, controlled facilities.
Team types
- Platform engineering teams building internal Kubernetes platforms.
- SRE/operations teams responsible for uptime and incident response.
- Security teams enforcing consistent baseline controls across environments.
- DevOps teams standardizing CI/CD to multiple deployment targets.
Workloads
- Stateful services that must remain on-prem (with robust storage planning).
- Low-latency APIs near data sources.
- Data ingestion and preprocessing pipelines at the edge.
- Modernization of legacy apps via containerization.
- AI/ML inference at the edge (hardware and driver support must be validated).
Architectures
- Hub-and-spoke hybrid architectures (central cloud + many edge sites).
- On-prem active/active or active/passive across two data centers.
- “Cloud control, local execution” patterns (cloud-based governance with local compute).
Real-world deployment contexts
- Single data center modernization with gradual migration to cloud.
- Multi-site retail deployments with standardized cluster builds.
- Regulated environments requiring strict network boundaries and local data processing.
Production vs dev/test usage
- Production: common when there is stable on-prem capacity, strict SLOs, and operational maturity.
- Dev/test: often limited, because you still need physical hardware. Many teams use GKE (cloud) for dev/test and promote to bare metal for production-like testing at key stages.
5. Top Use Cases and Scenarios
Below are realistic scenarios that align with what bare metal Kubernetes platforms are typically used for. For each, validate exact feature support in the official docs for your target version.
1) Data residency for regulated workloads
- Problem: Compliance requires data to remain in a specific facility/country.
- Why this service fits: Runs Kubernetes locally while retaining Google Cloud-aligned governance patterns.
- Example: A bank processes PII on-prem and exports only aggregated analytics to BigQuery in Google Cloud.
2) Edge inference for low-latency ML
- Problem: Cloud round-trips add latency; bandwidth is limited.
- Why it fits: Local compute on bare metal can host inference services near sensors/devices.
- Example: A factory runs defect detection inference on-site and sends exceptions to cloud dashboards.
3) Modernizing legacy on-prem apps to containers
- Problem: Legacy apps are hard to patch and scale.
- Why it fits: Provides a Kubernetes landing zone without requiring immediate cloud migration.
- Example: A healthcare provider containerizes internal apps and standardizes deployments using GitOps.
4) High-performance workloads avoiding virtualization overhead
- Problem: Virtualization reduces performance consistency.
- Why it fits: Bare metal reduces overhead and can maximize throughput.
- Example: A media company runs on-prem transcode pipelines on dedicated servers.
5) Local processing for data gravity
- Problem: Petabyte-scale datasets are expensive/slow to move to cloud.
- Why it fits: Compute moves to data; hybrid integration enables selective cloud usage.
- Example: Genomics pipelines run on-prem; results and metadata are stored in cloud for collaboration.
6) Standardizing multi-site deployments with central governance
- Problem: Many sites drift in config/security over time.
- Why it fits: Fleet-style management + policy/config-as-code patterns reduce drift.
- Example: Retail chain deploys identical app stacks across 500 stores.
7) On-prem platform for sovereignty / air-gapped-like constraints (partial connectivity)
- Problem: Restricted networks cannot allow broad outbound access.
- Why it fits: You can design controlled egress to required Google endpoints (validate supported connectivity modes).
- Example: A public-sector site allows only limited egress for updates and auditing.
8) Hybrid microservices: on-prem core + cloud front-ends
- Problem: Core systems must remain on-prem; new services need internet scale.
- Why it fits: Supports hybrid architectures with clear network boundaries.
- Example: On-prem services handle transactions; cloud services handle web front-ends and global CDN.
9) Disaster recovery (DR) for critical services
- Problem: Need a second site and consistent Kubernetes platform for failover.
- Why it fits: Similar cluster builds across sites enable consistent DR runbooks.
- Example: Primary data center runs active; secondary runs warm standby with replicated data.
10) Consolidating inconsistent on-prem Kubernetes distributions
- Problem: Different teams run different Kubernetes flavors; upgrades are risky.
- Why it fits: Provides a supported distribution and standardized lifecycle tooling.
- Example: Enterprise retires multiple bespoke clusters and re-platforms onto a single supported stack.
11) Edge content caching and processing
- Problem: Bandwidth and latency challenges for media delivery.
- Why it fits: Run caching/proxy layers locally; integrate centralized monitoring.
- Example: Stadium venue runs local streaming services with upstream sync to cloud.
12) Secure enclave-like workloads with controlled egress
- Problem: Sensitive processing must remain inside a controlled perimeter.
- Why it fits: On-prem deployment allows strict network segmentation; integrate with cloud only as needed.
- Example: A research lab processes data locally and publishes only anonymized outputs.

7. Architecture and How It Works
High-level service architecture
A typical Google Distributed Cloud software for bare metal deployment includes:
- Control plane nodes (physical): run Kubernetes API server, etcd, controllers.
- Worker nodes (physical): run application workloads.
- Load balancing: software-based load balancing for Kubernetes Services/Ingress (commonly required for bare metal).
- Admin workstation / management host: runs the installer/lifecycle CLI and holds configuration artifacts.
- Connectivity to Google Cloud: registers clusters and enables fleet-level features (governance/observability) depending on configuration.
- Optional platform add-ons: policy enforcement, config sync/GitOps, service mesh, centralized ingress patterns.
Request, data, and control flow
Control flow (management plane) 1. Platform operator uses an admin workstation CLI to bootstrap or update the on-prem cluster. 2. Cluster is registered with Google Cloud (fleet/hub style). 3. Policies/config can be pushed down from Git repositories or fleet tooling (where enabled). 4. Observability agents can export metrics/logs to Google Cloud Operations (if configured).
Data flow (application traffic) – User requests arrive via on-prem network load balancer/ingress IPs and route to Kubernetes Services/Pods. – East-west traffic remains inside the on-prem cluster network; if service mesh is enabled, it may be mTLS-encrypted. – North-south traffic to Google Cloud services traverses your chosen connectivity (public internet with egress control, Cloud VPN, or Interconnect).
Integrations with related Google Cloud services (common)
- Artifact Registry: store and sign container images.
- Cloud Logging & Cloud Monitoring: centralized observability.
- Cloud IAM: identity and access for fleet-level administration.
- Cloud KMS (optional): key management patterns for secrets/encryption workflows (validate integration approach).
- Cloud VPN / Interconnect: private connectivity between on-prem and Google Cloud.
- Security Command Center (optional): security posture aggregation (verify applicability).
Dependency services (on-prem requirements)
- DNS and NTP services (reliable, low-latency).
- IP address management and routing (cluster CIDRs, service CIDRs, VIPs).
- Hardware management (BMC/IPMI/iDRAC/iLO), BIOS/firmware baselines.
- Storage platform (CSI driver-backed SAN/NAS or local storage strategy).
Security/authentication model (typical patterns)
- Kubernetes RBAC governs in-cluster permissions.
- Google Cloud IAM governs access to fleet-level features and APIs.
- Secure connectivity (TLS) is used for cluster registration and control plane interactions.
- Service mesh mTLS (optional) secures service-to-service traffic.
Networking model (typical considerations)
- Define:
- Node IP ranges
- Pod CIDR
- Service CIDR
- VIPs for control plane and ingress
- Ensure routing between subnets/VLANs used by nodes and any upstream load balancer or L2 advertisement mode.
- Plan egress controls to Google endpoints if you export telemetry or use cloud registries.
Monitoring/logging/governance
- Decide what telemetry is collected and where it is stored.
- Use labels/annotations/naming to keep cluster inventory manageable.
- Establish SLOs per site and per cluster tier.

8. Prerequisites
Because Google Distributed Cloud software for bare metal is hardware-based, prerequisites are more substantial than a typical cloud tutorial. Treat this as a serious infrastructure project.
Account / project / tenancy requirements
- A Google Cloud account and a Google Cloud project.
- Billing enabled on the project (even if you intend minimal usage).
- Appropriate Google Cloud organization policies reviewed (especially if you will use fleet registration and observability exports).
Permissions / IAM roles
Exact roles vary by workflow and evolve over time; verify in official docs for your version. Commonly needed:
- Ability to enable required APIs in the project.
- Ability to create and manage service accounts and keys (or Workload Identity patterns, if supported for your workflow).
- Permissions related to fleet/hub registration (for example, membership creation).
- Permissions to write logs/metrics if exporting to Cloud Logging/Monitoring.
Billing requirements
- A subscription / license may be required for Google Distributed Cloud software for bare metal (often associated with GKE Enterprise / Anthos-era licensing). Pricing is not purely “pay-as-you-go” like GKE; it can be contract/SKU based.
- Additional Google Cloud services used (Artifact Registry, Logging, Monitoring, etc.) can generate usage-based charges.
CLI / SDK / tools needed
On an admin workstation (Linux is typical; verify supported OS in docs for your release):
gcloudCLI: https://cloud.google.com/sdk/docs/installkubectl(often installed via gcloud or separately)- The Google Distributed Cloud bare metal installer/lifecycle CLI (commonly referenced as a dedicated tool in docs).
sshtools and access to nodes.- Optional:
jq,yq,git, and a container runtime for tooling if required by the installer.
Region availability
- The software runs on your premises, but it integrates with Google Cloud APIs hosted in Google Cloud regions.
- Some features may require selecting a “home” region for APIs or management. Verify in docs.
Quotas / limits
- Google Cloud API quotas can apply for:
- Fleet registration/membership operations
- Logging/Monitoring ingestion rates
- Artifact Registry pulls (plus bandwidth)
- On-prem limits include:
- Maximum nodes per cluster, etcd sizing, and network scale constraints (verify per version in release notes).
Prerequisite services (on-prem)
At minimum, plan for:
- Bare metal servers that meet CPU/RAM/disk requirements (verify exact sizing guidance).
- Reliable DNS and NTP reachable by all nodes.
- Network plan for:
- Node IP addresses
- Pod CIDRs
- Service CIDRs
- Virtual IPs (VIPs) for control plane and ingress
- A load balancing approach supported for bare metal Kubernetes.
- Storage plan for persistent volumes (CSI driver compatibility must be validated).
Official docs start point: https://cloud.google.com/distributed-cloud/bare-metal/docs
9. Pricing / Cost
Pricing for Google Distributed Cloud software for bare metal is often not a simple per-second compute rate like public cloud VMs. It typically includes software subscription and support, plus any Google Cloud service consumption you enable.
Pricing dimensions (typical)
Always confirm on the official pricing page(s) because SKUs and packaging can change.
-
Software subscription / licensing – Often priced by capacity (for example, vCPU-based) and/or cluster/node counts. – Often sold with support tiers and contract terms. – This may be aligned with broader GKE Enterprise pricing/packaging (verify).
-
Google Cloud consumption (optional but common) – Cloud Logging: ingestion volume, retention beyond free allotments, and log-based metrics. – Cloud Monitoring: metric volume, API usage, retention. – Artifact Registry: storage + egress/requests. – Networking: egress charges if pulling images or exporting telemetry over the internet; VPN/Interconnect costs if used.
-
Your on-prem infrastructure costs (always) – Server capex or leasing – Data center power and cooling – Rack/space – On-prem networking equipment – Hardware maintenance contracts – Staff time for operations
Free tier (if applicable)
- Google Cloud has free tiers for some services (Logging/Monitoring have free allocations), but whether your overall setup stays within free tiers depends on telemetry volume and retention needs.
- The software subscription itself typically does not have a “free tier” in the way cloud managed services sometimes do. Verify in official docs and with Google Cloud sales.
Cost drivers
- Number of cores/vCPUs covered by license/subscription.
- Number of clusters and sites (operational overhead scales non-linearly).
- Observability volume (logs and metrics can be large for Kubernetes).
- Container image storage and distribution (Artifact Registry storage, egress).
- Network architecture (VPN/Interconnect, egress filtering, proxying).
Hidden / indirect costs
- Hardware refresh: Kubernetes platforms pressure you toward consistent hardware generations; mixed fleets can raise operational complexity.
- Spare capacity: you need headroom for upgrades, failures, and bursts.
- Storage reliability: persistent workloads can require enterprise storage and skilled storage operations.
- Security operations: vulnerability scanning, patch windows, and auditing.
Network/data transfer implications
- Exporting logs/metrics to Google Cloud can create:
- Internet egress from your site (your ISP costs)
- Google Cloud ingestion charges (service-dependent)
- Pulling images from Artifact Registry across sites:
- Consider caching/replication strategies
- Consider private connectivity (VPN/Interconnect) if needed
How to optimize cost (practical)
- Right-size telemetry:
- Reduce noisy logs
- Tune log retention
- Use sampling where appropriate
- Use local registries or caching when appropriate (but consider security and supply-chain controls).
- Standardize cluster sizes and avoid many tiny clusters with high operational overhead.
- Plan capacity:
- Avoid chronic overprovisioning
- Maintain minimal necessary N+1 redundancy
- Automate patching, configuration, and drift control to reduce labor cost.
Example low-cost starter estimate (model, not numbers)
Because exact prices are SKU/contract dependent, here’s a safe way to estimate without inventing figures:
- Software: minimum subscription covering a small cluster footprint (e.g., a single non-production cluster with a small number of worker cores).
- Cloud costs:
- Minimal Artifact Registry storage (a few GB)
- Minimal log ingestion by restricting verbose logs in non-prod
- On-prem:
- Reuse existing lab servers
- Keep redundancy modest (understanding this may not match production best practices)
Use:
– Google Cloud Pricing Calculator: https://cloud.google.com/products/calculator
– Official pricing pages (verify current URLs):
– Distributed Cloud pricing: https://cloud.google.com/distributed-cloud/pricing (verify)
– GKE Enterprise pricing (if applicable): https://cloud.google.com/kubernetes-engine/enterprise/pricing (verify)
Example production cost considerations (what to model)
- 2+ sites (primary + DR) or many edge sites.
- 3-node control plane per cluster, multiple worker pools.
- Enterprise storage and backup.
- Observability at scale (metrics/logs/events).
- Private connectivity to Google Cloud.
- Support tier aligned with your SLOs (24/7 for critical workloads).
10. Step-by-Step Hands-On Tutorial
This lab is designed to be realistic and executable for teams that already have (or can access) a small on-prem bare metal environment. If you do not have bare metal hardware, you can still follow the Google Cloud project and fleet setup steps, but cluster creation requires physical servers and a supported topology.
Because installer commands and configuration fields can vary by version, treat the cluster creation portion as version-sensitive and cross-check with the official “Create clusters” guide for your release:
https://cloud.google.com/distributed-cloud/bare-metal/docs
Objective
Create (or onboard) a Google Distributed Cloud software for bare metal cluster into Google Cloud, deploy a sample app, verify ingress/service exposure, and validate fleet visibility and basic observability.
Lab Overview
You will:
- Prepare a Google Cloud project and enable required APIs.
- Install and authenticate the Google Cloud CLI on an admin workstation.
- Obtain and configure the Google Distributed Cloud software for bare metal lifecycle tooling (version-specific).
- Create or validate a cluster configuration (IP ranges, VIPs, node inventory).
- Create the cluster (or connect to an existing one).
- Deploy a sample NGINX app and expose it internally.
- Validate cluster health, workload access, and fleet registration.
- Clean up the sample workload (and optionally delete the cluster).
Step 1: Prepare your Google Cloud project
What you’ll do – Select or create a project. – Enable billing. – Enable required APIs.
Commands (example)
# Set your project
gcloud config set project YOUR_PROJECT_ID
# Confirm account
gcloud auth list
# Enable common APIs (exact list varies; verify in docs)
gcloud services enable \
container.googleapis.com \
gkehub.googleapis.com \
iam.googleapis.com \
serviceusage.googleapis.com \
logging.googleapis.com \
monitoring.googleapis.com \
artifactregistry.googleapis.com
Expected outcome – APIs are enabled successfully. – Your project is ready to register clusters and use supporting services.
Verification
gcloud services list --enabled --filter="name:gkehub OR name:artifactregistry"
Step 2: Create a least-privilege service account for registration (version-dependent)
Many hybrid/on-prem registration workflows use a Google Cloud service account. Some environments can use other identity approaches; follow the official docs for your version.
Commands (example)
export PROJECT_ID="YOUR_PROJECT_ID"
export SA_NAME="gdc-bm-register"
export SA_EMAIL="${SA_NAME}@${PROJECT_ID}.iam.gserviceaccount.com"
gcloud iam service-accounts create "${SA_NAME}" \
--display-name="GDC Bare Metal Registration SA"
# Grant roles (verify least-privilege roles in official docs)
gcloud projects add-iam-policy-binding "${PROJECT_ID}" \
--member="serviceAccount:${SA_EMAIL}" \
--role="roles/gkehub.admin"
gcloud projects add-iam-policy-binding "${PROJECT_ID}" \
--member="serviceAccount:${SA_EMAIL}" \
--role="roles/logging.logWriter"
gcloud projects add-iam-policy-binding "${PROJECT_ID}" \
--member="serviceAccount:${SA_EMAIL}" \
--role="roles/monitoring.metricWriter"
Expected outcome – A service account exists with permissions to register memberships and write telemetry (if used).
Verification
gcloud iam service-accounts describe "${SA_EMAIL}"
Caveat: The correct IAM roles can vary by feature set (policy, config sync, connect gateway, etc.). Verify in official docs and security review.
Step 3: Prepare the admin workstation
What you’ll do
– Install gcloud, kubectl, and required tooling.
– Ensure SSH connectivity to all bare metal nodes.
Checklist – Admin workstation can resolve DNS for all nodes. – Admin workstation can reach: – Node management IPs via SSH – Any required BMC endpoints (if used) – NTP/DNS services – Google Cloud APIs (either direct internet or via controlled proxy)
Commands (example)
# Install kubectl via gcloud (one option)
gcloud components install kubectl
# Confirm versions
gcloud --version
kubectl version --client=true
Expected outcome – Tooling is installed. – Workstation can reach required endpoints.
Verification
# Confirm API reachability
gcloud projects describe "${PROJECT_ID}"
# Confirm SSH reachability to a node (example)
ssh USER@NODE_IP "hostname && uname -a"
Step 4: Obtain the Google Distributed Cloud software for bare metal installer/lifecycle CLI
The exact download method and CLI name/version (and whether it’s bundled) is release-specific.
- Follow the official install tooling instructions in docs:
https://cloud.google.com/distributed-cloud/bare-metal/docs
Expected outcome – You have the correct lifecycle CLI on the admin workstation. – You can run a version command.
Example verification (illustrative)
# Example only. Verify the correct command for your release.
bmctl version
If you’re unsure, stop here and confirm the tooling section for your version.
Step 5: Generate and edit a cluster configuration (version-sensitive)
Most bare metal Kubernetes installers require you to define:
- Control plane VIP
- Ingress VIP(s)
- Pod CIDR and Service CIDR
- Node IP inventory and roles
- Load balancer address pools
- SSH keys and OS user
- Proxy settings (if your site uses controlled egress)
- Registry settings (Artifact Registry or local mirrors)
Create a config skeleton (illustrative)
# Example only. Verify your release command.
bmctl create config -c bm-cluster-1
You will typically get a directory with a config file to edit. Carefully set:
clusterNamecontrolPlaneVIPingressVIPpodCIDR,serviceCIDR- node addresses for control plane and workers
- network mode (L2/BGP for LB) as supported
Expected outcome – A config file exists and is updated for your site.
Verification Run a preflight validation if your version provides it:
# Example only. Verify your release command.
bmctl check config -c bm-cluster-1
Step 6: Create the cluster (or onboard an existing cluster)
Path A: Create a new cluster (common for first-time installs)
# Example only. This can take significant time.
bmctl create cluster -c bm-cluster-1
Path B: If a cluster already exists, set kubeconfig and skip creation
– Obtain the kubeconfig according to your operational procedures (secured).
– Ensure kubectl can connect.
export KUBECONFIG=~/kubeconfig-bm-cluster-1
kubectl get nodes
Expected outcome
– Cluster creation completes (Path A), or you can access the existing cluster (Path B).
– Nodes show Ready.
Verification
kubectl get nodes -o wide
kubectl get pods -A
Step 7: Register the cluster to Google Cloud (fleet/hub)
Registration steps vary by version and chosen connectivity model. Official docs will specify the correct commands and required agents.
Start with the docs section for “Connect clusters / register / fleet”:
https://cloud.google.com/distributed-cloud/bare-metal/docs
Expected outcome – Cluster appears in Google Cloud as a registered membership.
Verification (example)
# Command group naming can vary (fleet vs hub). Verify in official docs.
gcloud container fleet memberships list
If you use a UI-driven approach, confirm the cluster shows in the Google Cloud Console under the relevant fleet/hybrid management pages.
Step 8: Deploy a sample application and expose it
This portion is Kubernetes-standard and works the same on bare metal.
Deploy NGINX
kubectl create namespace demo
kubectl -n demo create deployment web --image=nginx:stable
kubectl -n demo expose deployment web --port=80 --type=ClusterIP
Expected outcome – Deployment exists and pods are running.
Verification
kubectl -n demo get deploy,rs,pods,svc -o wide
Test access (port-forward for a guaranteed test)
kubectl -n demo port-forward svc/web 8080:80
In another terminal:
curl -I http://127.0.0.1:8080
You should see HTTP/1.1 200 OK.
To test “real” ingress/LB behavior you must configure an Ingress controller and VIPs/LB pools correctly for your environment. The specifics depend on your cluster networking and chosen ingress pattern—verify in the official docs and your platform standard.
Step 9: (Optional) Pull images from Artifact Registry
If your cluster has egress to Google Cloud and you want a controlled supply chain, you can use Artifact Registry.
Create a repo
gcloud artifacts repositories create bm-demo \
--repository-format=docker \
--location=us-central1 \
--description="Demo repo for bare metal tutorial"
Expected outcome – A Docker repository exists.
Verification
gcloud artifacts repositories list --location=us-central1
You can then push an image and deploy it to the cluster. In production, prefer private connectivity and/or caching strategies.
Validation
Run this checklist:
-
Kubernetes healthy
bash kubectl get nodes kubectl get pods -A -
Workload reachable –
curlvia port-forward returns200 OK. -
Fleet registration visible
bash gcloud container fleet memberships list -
Basic logs present – If using Cloud Logging integration: verify logs appear in Google Cloud Console (Logs Explorer), respecting your retention and privacy policies.
Troubleshooting
Common issues and practical fixes:
-
Nodes not Ready – Check node OS prerequisites (kernel modules, time sync, network). – Verify DNS and NTP are correct across all nodes. – Inspect:
bash kubectl describe node NODE_NAME kubectl get events -A --sort-by=.lastTimestamp | tail -n 50 -
Installer preflight fails – IP overlap between node subnet, Pod CIDR, and Service CIDR. – VIP addresses not reachable/advertised correctly. – Missing L2 adjacency (if using L2 advertisement for load balancing). – Fix: correct network plan; rerun preflight.
-
Cannot register cluster to Google Cloud – Outbound firewall blocks required endpoints. – Service account permissions insufficient. – Time drift (TLS failures). – Fix: verify proxy/egress rules; confirm roles; validate NTP.
-
Images won’t pull – No egress to registry. – DNS issues. – Registry auth misconfigured. – Fix: ensure egress, DNS, and credentials; consider a local registry mirror.
-
Ingress/VIP not reachable – Load balancer address pool misconfigured. – Upstream routing missing to VIP subnet. – Fix: confirm routing and L2/BGP settings (as designed).
Cleanup
Remove the demo workload
kubectl delete namespace demo
Optional: delete Artifact Registry repo
gcloud artifacts repositories delete bm-demo --location=us-central1
Optional: delete the cluster (destructive) If you created a non-production cluster and want to remove it:
# Example only. Verify command for your release.
bmctl delete cluster -c bm-cluster-1
Also remove fleet registration if required by your governance process (commands vary; verify in docs).
11. Best Practices
Architecture best practices
- Standardize cluster topologies:
- Define a small set of reference sizes (small/medium/large) with clear node counts and resource headroom.
- Separate failure domains:
- Use rack/PDUs/network redundancy and spread control plane nodes across failure domains where possible.
- Plan for upgrades:
- Always keep free capacity for rolling upgrades and node replacement.
- Define storage tiers:
- Stateless vs stateful separation; choose enterprise CSI-backed storage for critical stateful apps.
IAM / security best practices
- Least privilege:
- Separate roles for cluster admins, platform ops, and application teams.
- Break-glass access:
- Maintain a secure, audited emergency access method if fleet connectivity is unavailable.
- Supply chain security:
- Use signed images, private registries, and strict admission policies where supported.
- Secrets management:
- Avoid storing secrets in Git; use a secrets manager pattern and limit RBAC access.
Cost best practices
- Control observability spend:
- Reduce noisy logs; set retention policies; export only what you need.
- Avoid cluster sprawl:
- Many small clusters increase overhead; consider fewer, well-governed clusters per site when appropriate.
- Use capacity planning:
- Track utilization and forecast growth; manage headroom deliberately.
Performance best practices
- Pinpoint bottlenecks:
- CPU contention, storage IOPS, and network oversubscription are common culprits.
- Right-size control plane:
- Underpowered control plane leads to slow scheduling and API timeouts.
- Locality-aware design:
- Keep chatty services in the same site/cluster; reduce cross-site calls.
Reliability best practices
- Backups and restore drills:
- For etcd and critical state (and app data), implement backups and test restores.
- SLOs per site:
- Define “edge SLO” separately from “cloud SLO” since site failures differ.
- Runbooks:
- Document node replacement, certificate rotation, and recovery procedures.
Operations best practices
- Golden images and firmware baselines:
- Keep server BIOS/firmware consistent; track changes.
- Proactive monitoring:
- Monitor hardware (SMART, RAID, NIC errors), not just Kubernetes.
- GitOps for platform config:
- Version control cluster add-ons, policies, and namespaces.
- Change management:
- Use staged rollouts: dev → staging → production sites.
Governance / tagging / naming best practices
- Consistent naming for:
- Clusters:
site-env-purpose(e.g.,dfw-prod-payments) - Namespaces:
team-app-env - Labels:
owner,cost-center,data-classification - Maintain a cluster inventory registry with:
- Site, rack, node serials, OS versions, Kubernetes versions, and support status.
12. Security Considerations
Identity and access model
- Kubernetes RBAC controls in-cluster permissions.
- Google Cloud IAM controls who can view/register/manage clusters via fleet/hub features and associated APIs.
- Use separate identities for:
- Platform operators
- CI/CD automation
- Observability export agents (if applicable)
Encryption
- In transit:
- TLS for Kubernetes API and control plane communications.
- mTLS for service-to-service when a mesh is enabled.
- At rest:
- Disk encryption depends on your on-prem strategy (hardware encryption, OS-level encryption, storage array encryption).
- Verify how etcd encryption and secrets encryption at rest are configured for your release.
Network exposure
- Treat ingress VIPs as production endpoints:
- Use firewalls, WAF (if applicable), and network segmentation.
- Limit control plane exposure:
- Control plane VIP should be reachable only from trusted admin networks.
- Control egress:
- Use proxies and explicit allowlists for Google endpoints if required.
Secrets handling
- Don’t store secrets in plaintext manifests.
- Use Kubernetes secrets carefully; restrict RBAC.
- Consider external secret management patterns (verify supported integrations and operational approach).
Audit / logging
- Enable audit logs where appropriate and ensure they are retained securely.
- Decide what logs are exported to Google Cloud vs retained locally (privacy and regulatory impact).
- Monitor privileged operations: cluster-admin bindings, admission policy changes, and secret reads.
Compliance considerations
- Map controls to frameworks (PCI, HIPAA, SOC 2, ISO 27001) using:
- Identity control
- Change management
- Vulnerability management
- Logging and retention
- If data must not leave a site, ensure:
- Telemetry exports are filtered/anonymized appropriately.
- Container image pulls and updates meet policy.
Common security mistakes
- Wide-open Kubernetes API server exposure.
- Using shared admin kubeconfigs without rotation.
- Allowing unrestricted egress from workloads.
- No admission control / policy enforcement for privileged containers.
- Logging sensitive data (tokens, PII) into centralized systems.
Secure deployment recommendations
- Segment networks: admin/mgmt, node, pod, and external ingress.
- Enforce least privilege RBAC and IAM.
- Use policy-as-code to prevent privileged pods and hostPath abuse (where supported).
- Establish a patching cadence and vulnerability scanning pipeline.
- Implement an incident response plan for both cloud and site-level failures.
13. Limitations and Gotchas
These are common realities for bare metal Kubernetes platforms; confirm exact constraints in official docs and release notes.
Known limitations (typical)
- Not fully managed: you manage hardware lifecycle, network, storage, and on-prem troubleshooting.
- Version compatibility: add-ons, service mesh, policy tooling, and Kubernetes versions must be kept in a supported combination.
- Feature parity: some GKE (cloud) features may not exist or may behave differently on bare metal. Verify the feature matrix.
Quotas / scale constraints
- Cluster/node scaling limits exist and vary by release.
- etcd performance limits can show up earlier on underpowered control planes.
Regional constraints
- Your workload runs on-prem, but:
- Some management plane services are regional in Google Cloud.
- You may need to choose regions for Artifact Registry, Logging, and Monitoring.
Pricing surprises
- Observability ingestion costs (logs/metrics) can grow quickly.
- Egress costs for pulling images to many sites/clusters can add up.
- Support/licensing terms may be capacity-based—plan for peak capacity, not average.
Compatibility issues
- Storage CSI driver compatibility must be validated.
- Kernel/OS requirements and NIC driver behavior matter on bare metal.
- Time sync (NTP) issues can break TLS and cluster registration.
Operational gotchas
- VIP announcements and load balancing on bare metal can fail due to L2/L3 mismatches.
- “Works in one site” can still fail in another due to subtle network differences.
- Hardware failures (disk, NIC) are frequent at scale—automate node replacement.
Migration challenges
- Moving from self-managed Kubernetes:
- Rebuilding clusters and reapplying manifests is straightforward, but
- identity, ingress, storage, and CI/CD integration often require redesign.
- Stateful workloads require careful data migration and rollback plans.
Vendor-specific nuances
- Fleet/hub registration and agent-based connectivity often require specific outbound endpoints—plan early with security/network teams.
- Some capabilities depend on licensing/edition—validate before committing.
14. Comparison with Alternatives
Google Distributed Cloud software for bare metal sits in a crowded hybrid/on-prem Kubernetes landscape. The “best” choice depends on how much you want Google Cloud integration, how standardized your on-prem environment is, and your operations maturity.

16. FAQ
1) Is Google Distributed Cloud software for bare metal the same as GKE?
No. GKE is a managed Kubernetes service running in Google Cloud. Google Distributed Cloud software for bare metal runs on your own physical servers and is operated on-prem, though it integrates with Google Cloud for management features.
2) Is this service fully managed by Google?
No. Google provides the software and support model, but you operate the on-prem environment: hardware, networking, storage, and many operational responsibilities.
3) Do I need internet connectivity from my data center to use it?
Often yes, at least for registration, updates, and optional observability/management integrations. Some constrained-network patterns may exist, but connectivity requirements are version- and feature-dependent. Verify in official docs.
4) Can I run it at the edge (retail stores, factories)?
Yes, that’s a common target, assuming you can meet hardware, power, cooling, network, and operational requirements.
5) What skills do my team need?
Linux administration, networking (L2/L3), Kubernetes operations, storage, security, and incident response. This is not a “set and forget” platform.
6) How does load balancing work on bare metal?
Bare metal clusters typically use software load balancing and VIP address pools rather than a cloud provider’s managed load balancer. Exact mechanisms depend on supported configurations—verify in docs.
7) How do upgrades work?
Typically via a supported lifecycle tool that orchestrates control plane and worker upgrades. You should test upgrades in a staging cluster and maintain capacity headroom.
8) Can I use Artifact Registry with on-prem clusters?
Often yes, if your clusters can reach Artifact Registry endpoints and are authorized. Plan for egress control, caching, and cost.
9) Can I keep logs on-prem and not export them to Google Cloud?
You can choose observability architecture based on requirements. Exporting to Cloud Logging/Monitoring is optional in many setups, but verify your version and support boundaries.
10) Does it support service mesh?
Service mesh capabilities are often available in hybrid platforms, but version support varies. Check the compatibility matrix for your cluster version and mesh version.
11) How do I enforce security policies across many clusters?
Use policy-as-code and centralized governance patterns (where supported) to enforce admission controls, baseline RBAC, and namespace standards.
12) How do I handle secrets securely?
Use least-privilege RBAC, avoid secrets in Git, and consider external secret manager patterns. Validate encryption-at-rest options for etcd and storage.
13) What’s the biggest operational risk?
Networking misconfiguration and lack of standardization across sites. The “same cluster config” can behave differently if VLANs, routing, MTU, or DNS differ.
14) Can I run stateful databases on it?
Yes, but you need a robust storage architecture (CSI driver, performance, backups, replication). Stateful workloads increase operational demands.
15) How is pricing determined?
Typically via subscription/licensing plus any Google Cloud usage for integrated services. Exact SKUs can change—use official pricing pages and consult Google Cloud sales for accurate estimates.
16) How do I decide between bare metal and a VMware-based approach?
Choose bare metal when you want to avoid virtualization overhead or you’re standardized on physical servers. Choose VMware-based if your operations and infrastructure are VMware-centric. Verify current Google Distributed Cloud options.
17) What’s the best way to start safely?
Start with a non-production pilot: one site, one cluster, limited workloads, strict network baselines, and a clear rollback plan. Build runbooks before scaling out.

23. Summary
Google Distributed Cloud software for bare metal is Google Cloud’s way to run a supported Kubernetes platform on your own physical servers, aligning on-prem and edge environments with Google Cloud governance patterns in the Distributed, hybrid, and multicloud category.
It matters because many organizations must keep workloads close to data for latency, sovereignty, or regulatory reasons—yet still want standardized Kubernetes operations, policy enforcement, and centralized visibility. The biggest cost considerations are typically subscription/licensing, on-prem infrastructure operations, and telemetry/image distribution costs to Google Cloud services. The biggest security considerations are network segmentation, egress control, least-privilege IAM/RBAC, and supply-chain controls.
Use it when you need on-prem/edge Kubernetes on bare metal with Google Cloud alignment and support. Avoid it if you want a fully managed cloud control plane or you lack the operational maturity to manage data center networking, hardware lifecycle, and upgrades.
Next learning step: Start with the official docs and validate your hardware/network prerequisites before any pilot deployment:
