A build in Knative is a process that creates a container image from source code.
18. What is a revision in Knative?
A revision in Knative is a specific version of an application that can be deployed and scaled independently.
19. What is a route in Knative?
A route in Knative is a way to expose a revision to incoming traffic.
20. What is a service in Knative?
A service in Knative is a higher-level abstraction that defines a set of routes and revisions.
21. What is a trigger in Knative?
A trigger in Knative is a way to automatically start a build or deploy a revision based on an event.
22. What is a source in Knative?
A source in Knative is a way to define where events come from, such as a Git repository or a message queue.
23. What is a sink in Knative?
A sink in Knative is a way to define where events go, such as a function or a message queue.
24. What is a broker in Knative?
A broker in Knative is a way to route events between sources and sinks.
25. What is a function in Knative?
A function in Knative is a serverless function that can be triggered by an event.
26. What is a container image?
A container image is a lightweight, standalone executable package that contains everything needed to run an application, including code, libraries, and dependencies.
27. What is a Dockerfile?
A Dockerfile is a text file that contains instructions for building a Docker container image.
28. What is a container registry?
A container registry is a place to store and distribute container images.
29. What is a Kubernetes cluster?
A Kubernetes cluster is a set of nodes that run containerized applications and services.
30. What is a node in Kubernetes?
A node in Kubernetes is a physical or virtual machine that runs containers.
31. What is a pod template in Kubernetes?
A pod template in Kubernetes is a specification for creating pods.
32. What is a replica set in Kubernetes?
A replica set in Kubernetes is a Kubernetes object that manages a set of replicas of a pod template.
33. What is a horizontal pod autoscaler in Kubernetes?
A horizontal pod autoscaler in Kubernetes is a Kubernetes object that automatically scales the number of replicas of a pod template based on CPU utilization.
34. What is a vertical pod autoscaler in Kubernetes?
A vertical pod autoscaler in Kubernetes is a Kubernetes object that automatically adjusts the resource requests and limits of containers based on their resource usage.
35. What is a service mesh?
A service mesh is a dedicated infrastructure layer for managing service-to-service communication within a microservices architecture.
36. What is a sidecar container?
A sidecar container is a container that runs alongside the main container in a pod and provides additional functionality, such as logging or monitoring.
37. What is a circuit breaker?
A circuit breaker is a design pattern for handling network failures in a distributed system.
38. What is a load balancer?
A load balancer is a device or software that distributes network traffic across multiple servers.
39. What is a health check?
A health check is a periodic check to ensure that a service is running and responding correctly.
40. What is a rolling update?
A rolling update is a deployment strategy that updates a service by gradually replacing old instances with new ones.
41. What is a canary deployment?
A canary deployment is a deployment strategy that releases a new version of a service to a small percentage of users to test for issues before rolling it out to everyone.
42. What is a blue-green deployment?
A blue-green deployment is a deployment strategy that releases a new version of a service alongside the old version and switches traffic to the new version once it is ready.
43. What is a feature flag?
A feature flag is a way to toggle a feature on or off in a service based on a configuration setting.
44. What is a monolith?
A monolith is a large, complex application that is difficult to maintain and scale.
45. What is a microservices architecture?
A microservices architecture is an approach to software development that structures an application as a collection of small, independent services that communicate with each other through APIs.
46. What is a serverless function?
A serverless function is a piece of code that runs in response to an event, without the need for a dedicated server or infrastructure.
