ToDo

• Additional New Lessons

  • API: Run Foo Controller against https://github.com/kcp-dev/kcp instead of "real" (mini)kube

  • https://sdk.operatorframework.io (https://github.com/operator-framework/operator-sdk)

  • Testing controllers? https://book.kubebuilder.io/cronjob-tutorial/writing-tests.html

  • API: OpenAPI schema in separate file outside of CRD YAML, so that it's validated by super-linter's VALIDATE_OPENAPI

  • API: Generate OpenAPI schema from ProtoBuf PB? See https://cuelang.org/docs/integrations/protobuf/ and https://cuelang.org/docs/integrations/openapi/

  • https://googlecontainertools.github.io/kpt/

  • https://fluxcd.io

  • Signal handling etc.

    • https://cloud.google.com/blog/products/containers-kubernetes/kubernetes-best-practices-terminating-with-grace
    • https://docs.docker.com/engine/reference/builder/#stopsignal
    • https://github.com/nginxinc/docker-nginx/search?q=STOPSIGNAL

    • https://github.com/Yelp/dumb-init
    • https://aws.amazon.com/blogs/containers/graceful-shutdowns-with-ecs/

• Listen in to Kubebuilder, Controller Runtime, and Controller Tools Meeting

• Use https://github.com/monopole/mdrip to validate the lessons! (And add a "used by" section to its README.) Contribute the same to kubebuilder, see kubernetes-sigs/kubebuilder#711

• https://cloud.google.com/shell/docs/cloud-shell-tutorials/tutorials

• Other Kubernetes distributions than minikube:

  • kubeadm.. on CoreOS?
  • https://k3s.io (https://k3d.io)
  • https://github.com/rootless-containers/usernetes
  • https://microk8s.io
  • https://k0sproject.io

• CoreOS instead of Debian on GCP: Debian works, but CoreOS SSH keys are somehow missing: (update https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-gcp/)

• https://codelabs.developers.google.com ?

• contribute https://github.com/vorburger/LearningKubernetes-CodeLabs/blob/develop/docs/kubebuilder.md to https://book.kubebuilder.io as simpler first lesson before the full-blown cronjob example.
