Tasks for Kubernetes v1.24

[sbueringer]

This issue is tracking the list of tasks that should be implemented when Kubernetes v1.24 is released. Currently, we are waiting for the Kubernetes release

• CI:

  • CAPD: 🐛 Use Kubernetes 1.24 in quickstart and CAPD, bump to kind v0.14 #6513
    • docker.yaml: KUBERNETES_ env vars in variables
    • kind_provider.go, docker/*, ... (just grep for the previously used version in CAPD)
  • Jobs: Cluster API jobs update to Kubernetes 1.24 kubernetes/test-infra#26196
    • Add new periodic upgrade jobs, for all release where we want to support the new Kubernetes version
    • Adjust presubmit jobs so that we have the latest upgrade jobs available on PRs (for all releases)
    • Update INIT_WITH_KUBERNETES_VERSION

• Book:

  • Update supported versions in versions.md 📖 update supported Kubernetes versions #6543
  • Update and test quickstart 🐛 Use Kubernetes 1.24 in quickstart and CAPD, bump to kind v0.14 #6513
  • Update job documentation in CAPI (jobs.md) 📖 Update job documentation #6567

• Release specific issues:

  • Label/ taint handling for 1.24 mentioned in Rename references to "node-role.kubernetes.io/master" #3279
    • PR(main): 🌱 Support new control plane label and taint #5919
    • PR(release-1.1): 🌱 Support new control plane label and taint #6084
    • Let's add notes to our releases about label/taint changes 📖 update supported Kubernetes versions #6543
  • Handle kubeadm 1.24 kubelet ConfigMap name change #5921
    • PR(main): 🌱 handle kubeadm 1.24 kubelet ConfigMap name change #6176
    • PR(release-1.1): 🌱 handle kubeadm 1.24 kubelet ConfigMap name change #6206
  • Use socket with unix:/// in CAPD. #6155
    • Use socket with unix:/// in CAPD
    • Document that users should migrate (1. in Use socket with unix:/// in CAPD. #6155 (comment)) 📖 update supported Kubernetes versions #6543
  • Make sure kubeadm 1.24 socket auto-discovery doesn't lead to issues #5920
  • Check if contextual logging is merged in the klog version we will upgrade to. If yes migrate to klog.Background()
    • xref: Consider handling values that implement the Stringer interface when logging values  kubernetes/klog#302 (comment) contextual logging kubernetes/klog#296
      • PR: 🌱 logging: use klog.Background #6602

• After a Kubernetes release is cut a controller-runtime version is created. When the CR version is available we have to:

  • Use new Kubernetes Go libraries (controller-runtime, controller-tools, client-go, ...)
    • This can include upgrading the Go version (we're using the same as k/k)
    • PR: 🌱 Upgrade to controller-runtime v0.12.2 and k8s.io/* v0.24.* #6467
    • PR: 🌱 Upgrade controller-tools to v0.9.1 #6542
    • Upgrade to controller-runtime v0.12.2 Upgrade to controller-runtime v0.12.2 #6650
  • Update KUBEBUILDER_ENVTEST_KUBERNETES_VERSION in Makefile
    • PR to bump kubebuilder tools: 🌱 Build kubebuilder-tools for Kubernetes 1.24.1 kubebuilder#2709
    • follow-up: CAPI PR: 🌱 bump envtest to v1.24.1 #6604
  • If the new Kubernetes version uses a new Go version
    • Jobs: Update kubekins-e2e images used for jobs running against main
      • Potentially it makes sense to switch to the latest ("master") version of kubekins-e2e if there is no -{KUBERNETES-VERSION} tag of the image already.
      • PRs: jobs/cluster-api: bump kubekins to v20220428-de61deb68b-1.24 for main presubmits kubernetes/test-infra#26155 & jobs/cluster-api: bump kubekins to v20220428-de61deb68b-1.24 for main periodics kubernetes/test-infra#26156
      • Follow-up PR in CAPI: 🐛 Support Go 1.18: Bump apidiff to v0.4.0 #6601
    • Update go version: ✨ Bump Go to 1.18.3 for Tiltfile, Container Images, Netlify #6616
      • .github/workflows
      • Tiltfile
      • Makefiles
      • hack/ensure-go.sh
      • netlify.toml
      • [opt] go.mod files (only if we want to increase the minimum supported version of consumers) [DOES NOT APPLY]
    • Update go version:
      • cloudbuild YAMLs (to use an image with the current go version)
        • test-infra PR: gcb-docker-gcloud: bump to Go 1.18 kubernetes/test-infra#26540
        • CAPI PR: 🌱 cloudbuild: bump to Go 1.18 #6617
      • .golangci.yml (+ corresponding workflow file)
        • for golangci-lint we have to wait for the next release which has a fix for gci linter no longer autofixing import orders #6350 + Go 1.18 support
