• Auto generate the CRD schema version - I've some ideas around that which would help k8s: clarify CRD schema versioning and its update process #12493 as well.
  • Automatic detection of CRD changes and increment the CRD schema validation version
• Resolve Migrate away from top-level "description" to spec.description in CNP & CCNP CRDs #13155 by creating a preflight check to ensure no policies have a top-level description
• Generate CRDs for all other resources: Automate generation of CiliumNode, CiliumIdentity, & CiliumEndpoint CRDs using controller-gen #11476
• GitHub Action to run make manifests to generate the CRDs and check for any drift (similar to make generate-k8s-api)
  • Generating CRDs is now part of the make generate-k8s-api target: Invoke go-bindata from the vendor directory instead of requiring it explicitly #12805
• Transition from v1beta1 to v1 CRDs: Upgrade CRDs (apiextensions) from v1beta1 to v1 #11477
• Move the CRD into the quick-install.yaml by putting in the CRD directory of helm. There is a special directory for CRDs in helm: Move Cilium CRDs to special Helm directory for auto installation upon helm install #13310
  • See comment below on this item: CRD schema auto generation follow ups #12737 (comment)
  • Obsoleted by CRD schema auto generation follow ups #12737 (comment)
• Promote https://github.com/christarazi/controller-tools to be under the Cilium org (from Fix controller-tools module #13055 (comment)): vendor: Promote controller-tools fork to cilium repo #18185

Higher priority

• Add documentation to the K8s compatibility section about people upgrading from K8s < 1.16 to K8s >= 1.16 while running Cilium >= 1.9 should make sure to run the pre-flight checker from above: docs: Add note for users upgrading K8s #13273
• Remove "dead" code that CRDs (Upgrade CRDs (apiextensions) from v1beta1 to v1 #11477 (comment)): k8s: Remove CRD deleting functionality #13272
• Now that we depend on the operator to do cluster operation, the CRD update / check can be done by the operator instead of the cilium-agents: operator: Move CRD registration to operator #13285
• Replace go-bindata with //go embed Use go embed and remove go-bindata dependency #15834
