Support Kubernetes v1.24.1 and other new versions

[brandan-schmitz]

Your current KubeKey version

v2.1.1

Describe this feature

Kubernetes recently released a new round of updates on May 24th, 2022:

• v1.21.13
• v1.22.10
• v1.23.7
• v1.24.1

Describe the solution you'd like

Add the ability to use these versions with the --with-kubernetes flag. Currently they cannot be used as the sha256 checksum and version is not in the application.

Hi @brandan-schmitz , thanks for your feedback!
Support more Kubernetes versions are very necessary.
I think this fits as a "good-first-issue" so if you're interested in fixing it, please let me know.

@24sama I would be be willing to work on this, what is the process that has been used for obtaining the checksum currently used in the project? I compared some of them to the checksums listed at https://www.downloadkubernetes.com/ (linked in the official k8s documentation) however they do not seem to match.

I also see that currently it pulls from a google storage account, however when I go to the links as I would expect them to be based on the contents of pkg/files/file.go it is unable to locate the files.

Hi @brandan-schmitz
For now, kk need to add the sha256 into pkg/files/file.go, it's really not elegant and flexible.
So we need to increase this map

kubekey/pkg/files/file.go

Line 304 in b19724c

FileSha256 = map[string]map[string]map[string]string{

And I think you can get the sha256 checksum by the following link, this comes from the official doc: https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/

Example:

# amd64
https://storage.googleapis.com/kubernetes-release/release/v1.24.1/bin/linux/amd64/kubectl.sha256
https://storage.googleapis.com/kubernetes-release/release/v1.24.1/bin/linux/amd64/kubelet.sha256
https://storage.googleapis.com/kubernetes-release/release/v1.24.1/bin/linux/amd64/kubeadm.sha256

# arm64
https://storage.googleapis.com/kubernetes-release/release/v1.24.1/bin/linux/arm64/kubectl.sha256
https://storage.googleapis.com/kubernetes-release/release/v1.24.1/bin/linux/arm64/kubelet.sha256
https://storage.googleapis.com/kubernetes-release/release/v1.24.1/bin/linux/arm64/kubeadm.sha256

After that we need to add some new elements to this array and the docs:

kubekey/pkg/version/kubernetes/version_enum.go

Line 90 in b19724c

func SupportedK8sVersionList() []string {

@24sama I have created a PR that adds all the versions of Kubernetes that were missing starting with version 1.21.0 as that is the oldest currently supported version. The PR has been linked to this issue.
