Version

As explained in Effective Platform Engineering

An API version is an identifier that distinguishes a particular compatibility and behavior contract for an API.

An API version identifies a particular compatibility and behavior contract. Treating versions explicitly lets platform teams manage change without breaking existing deployments. section 9.3

A Kubernetes API version follows an incremental deprecation path:

  • Promote an API from v1alpha1 to v1beta1, then mark v1alpha1 as deprecated in the next release. section 9.3
  • Keep the deprecated version usable for two release cycles to provide backward compatibility. section 9.3
  • Scan deployments after upgrades, identify outdated versions, and notify owning teams before removal causes failures. section 9.3
apiVersion: admissionregistration.k8s.io/v1alpha1
Kind: MutatingWebHook

apiVersion: apps/v1
Kind: Deployment

Compare version declarations for admission registration and deployment APIs. section 9.3

How Effective Platform Engineering covers it

How deep it goes
Explains deprecation timing, compatibility windows, cluster scanning, and team notification, but not versioning implementation internals.
Examples
Uses admission registration and deployment manifests, plus an upgrade watcher that creates Jira issues for affected teams.
What it assumes
Assumes familiarity with Kubernetes upgrades, deployments, API schemas, and deployment metadata.
What you can do after
Diagnose outdated API usage and coordinate migrations before a Kubernetes release removes compatibility.
How it connects
Connects API versions with Kubernetes upgrades, backward compatibility, deprecation, deployments, metadata, and event-driven release processes.
