version 참고

  • kubernetes와 관련된 image는 https://github.com/kubesphere/ks-installer/releases 에서 주요 release에만 포함되는 image-list.txt파일을 참고
  • kubekey의 버전별로 kubernetes, kubesphere의 최신 지원 버전이 있음
    • kubekey/version/components.json
    • kubekey/cmd/kk/pkg/version/kubesphere/version_enum.go
    • kubekey/cmd/kk/pkg/version/kubernetes/version_enum.go
  • default 버전에 대한 설정은 kubekey/cmd/kk/apis/kubekey/v1alpha2/default.go 파일에 있다

참고

  • https://github.com/kubesphere/kubekey/blob/v3.0.13/docs/manifest_and_artifact.md
  • https://github.com/kubesphere/ks-installer/releases/download/v3.4.1/images-list.txt

    ## For now, if your cluster container runtime is containerd, KubeKey will add a docker 20.10.8 container runtime in the below list.
    ## The reason is KubeKey creates a cluster with containerd by installing a docker first and making kubelet connect the socket file of containerd which docker contained.
