Retrieves kubeconfig of the cluster(s) and prints it to stdout.

|
|
|
If you specify single CLUSTER_NAME, kubeconfig will have a CurrentContext set to CLUSTER_NAME and
|
|
will have its context defined.
|
|
|
|
If you specify multiple CLUSTER_NAME args, kubeconfig will contain contexts for all of them, but current one
|
|
won't be specified.
|
|
|
|
If you don't specify CLUSTER_NAME, kubeconfig will have multiple contexts for every cluster
|
|
in the airship site. Context names will correspond to cluster names. CurrentContext will be empty.

Specify a file where kubeconfig should be written

Merge site kubeconfig with existing kubeconfig file.

Keep in mind that this can override a context if it has the same name
