Request to support component uninstallation feature

[JohnNiang]

At present, official website has provided a document about how to uninstall each component.

But it's not very friendly for end users to execute so many command at the same time.

Therefore, I request to support component uninstallation in ks command. e.g.:

ks uninstall devops
ks uninstall logging
ks uninstall alerting
...

# Or uninstall all component but basic component
ks uninstall all

/kind feature

@JohnNiang: The label(s) kind/feature cannot be applied, because the repository doesn't have them.

hi @JohnNiang , this is great. Currently, the command ks install xxx --components devops,logging be able to install KubeSphere (with Kubernetes). So, I prefer to uninstall a component with the following command:

ks uninstall --components xxx

hi @mangoGoForward thanks for helping on this issue. Before you get started, you can share your idea of the command usage.

For DevOps uninstallation, @mangoGoForward could refer to kubesphere/website#2155 (comment).

Thanks, the comment of kubesphere/website#2155 and the document of how to uninstall each component help me a lot. The operation of change the value of enabled from true to false in ks-installer of the CRD ClusterConfiguration seems to be reusable, but remove related resource with each component is different, could we use switch flow to process?

We can define an interface for the component. Such as:

type component interface {
  install() error
  uninstall() error
  status()
  name()
}

then, provide the implements for the different components.

Got it, thanks.
