How Google Cloud Deployment Manager works and Architecture?

Google Cloud Deployment Manager (CDM) simplifies infrastructure deployments on Google Cloud Platform (GCP) by offering a powerful but intuitive system. Here’s a breakdown of how it works and its underlying architecture:

How it Works:

Template Authoring: You define your desired infrastructure state using YAML or Python templates. These templates specify resources like VMs, storage buckets, databases, and their configurations.
Deployment Configuration: Specify deployment parameters like project, region, and environment variables within a configuration file.
Deployment Trigger: Initiate the deployment using the gcloud CLI, SDKs, Cloud Build trigger, or an HTTPS request.
Template Expansion: CDM interprets the template and configuration file, resolving variables and building the complete deployment plan.
Resource Creation: Based on the plan, CDM calls the relevant Google Cloud APIs to create resources in the specified order while respecting dependencies.
Validation and Reporting: CDM validates resource creation and reports any errors. Once successful, it provides a detailed report of the deployed infrastructure.

Architecture:

Client: You interact with CDM through various clients like the gcloud CLI, SDKs, REST API, or integration with CI/CD tools.
Deployment Manager Service: This central service receives deployment requests, processes templates, and orchestrates resource creation.

Basic Tutorials of Google Cloud Deployment Manager: Getting Started

Deployment Manager lets you define configurations for your Google Cloud resources in YAML files and deploy them efficiently. Here’s a guided introduction to building your first stack:

1. Understand DM Configurations:

DM configurations describe the resources you want to create, using YAML syntax. They define resource types, properties, and configuration details.

2. Create a Basic Configuration:

Let’s deploy a simple web server on a Compute Engine instance:

YAML

resources:
  - name: my-instance
    type: compute.v1.instance
    properties:
      machineType: f1-micro
      disks:
        - boot:
            autoDelete: true
            initializeParams:
              image: debian-cloud/debian-9
      networkInterfaces:
        - accessConfigs:
            - name: my-access-config
              type: ONE_TO_ONE_NAT
          network: global

outputs:
  public-ip:
    value: !GetAtt my-instance.networkInterfaces[0].accessConfigs[0].natIP

Explanation:

resources: Defines the resources you want to create.
my-instance: Name of your Compute Engine instance.
type: Specifies the resource type (compute.v1.instance).
properties: Configure the instance with machine type, boot disk, and network interface.
outputs: Exposes the instance’s public IP for access.

3. Deploy the Configuration:

You can deploy DM configurations using:

gcloud: Run gcloud deployment-manager deployments create my-deployment --config=my-config.yaml (replace names accordingly).
DM console: In the Cloud Console, navigate to Deployment Manager > Deployments > Create deployment > Upload configuration.

4. Monitor and Manage your Stack:
