쿠버네티스 kubectl config 명령
Modify kubeconfig files using subcommands like "kubectl config set current-context my-context"
사용법
The loading order follows these rules:
1. If the --kubeconfig flag is set, then only that file is loaded. The flag may only be set once and no merging takes
place.
2. If $KUBECONFIG environment variable is set, then it is used as a list of paths (normal path delimiting rules for
your system). These paths are merged. When a value is modified, it is modified in the file that defines the stanza. When
a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the
last file in the list.
3. Otherwise, ${HOME}/.kube/config is used and no merging takes place.
Available Commands:
current-context Display the current-context
delete-cluster Delete the specified cluster from the kubeconfig
delete-context Delete the specified context from the kubeconfig
delete-user Delete the specified user from the kubeconfig
get-clusters Display clusters defined in the kubeconfig
get-contexts Describe one or many contexts
get-users Display users defined in the kubeconfig
rename-context Rename a context from the kubeconfig file
set Set an individual value in a kubeconfig file
set-cluster Set a cluster entry in kubeconfig
set-context Set a context entry in kubeconfig
set-credentials Set a user entry in kubeconfig
