Problem description
Kubernetes has a cadence of posting a new release every 3 to 6 months. A release has roughly a 12 - 14 month lifespan. To maintain CNCF certification, conformance (like Anuket) & currency with the latest releases, Airship needs to establish an ongoing cadence to continually uplift the supported Kubernetes version.

v1.21 was released for GA on 5/12/2021. While there are current efforts underway to uplift to v1.20 (#555, #556, #569, #570, #571), we want to shift to v1.21 for Airship v2.1. Ideally, with the v1.21 uplift, we establish a more general pattern of Kubernetes upgrades where we are not necessarily focusing on the individual providers.

K8s release information can be found here: https://kubernetes.io/releases/

Tasks

  • Determine more general approach for k8s upgrade (design call topic - see notes).
  • Ensure image builder images reflect v1.21
  • Using this approach, uplift the k8s version to v1.21 for:
    • Bare Metal - First priority
    • Azure - First priority
    • Docker - First priority
    • GCP - Second priority
    • Openstack - Second priority

Discussion of approach from 7/15 design call:

Providers:

  • Work backwards to the providers to ensure compatibility
  • Determine if we need to upgrade the CAPI provider to support the K8s upgrade? Hopefully decoupled events, but may be some dependencies
  • Use catalog overrides if issues with v1.21 or not supported

Hi, The patch set to uplift docker version to 1.21 is here - https://review.opendev.org/c/airship/airshipctl/+/795582
@eak13 - Can you also create a separate issue for uplifting docker version and assign it to me.
