Other changes and deprecations

  • In the kube-apiserver configuration, the --enable-admission-plugins parameter prohibits setting PodPreset;
  • The Docker runtime was officially marked as deprecated in version 1.20. You can still use Docker in the cluster for now, but the community plans to phase it out in future versions.

When upgrading some CCE clusters from version 1.16 to 1.20, the following new configurations need to be added to kube-apiserver. If the upgrade fails, you can submit a ticket to contact the administrator for handling:

Plain Text 
1--service-account-issuer=https://kubernetes.default.svc.cluster.local \
2--service-account-signing-key-file=/etc/kubernetes/pki/ca-key.pem \
3--api-audiences=kubernetes.default.svc \
