# kubectl config

> Manage Kubernetes configuration (kubeconfig) files for accessing clusters via `kubectl` or the Kubernetes API.
> By default, the Kubernetes will get its configuration from `${HOME}/.kube/config`.
> See also: `kubectx`, `kubens`.
> More information: <https://kubernetes.io/docs/reference/kubectl/generated/kubectl_config/>.

- Get all contexts in the default kubeconfig file:

`kubectl config get-contexts`

- Get all clusters/contexts/users in a custom kubeconfig file:

`kubectl config {{get-clusters|get-contexts|get-users}} --kubeconfig {{path/to/kubeconfig.yaml}}`

- Get the current context:

`kubectl config current-context`

- Set the default namespace of the current context:

`kubectl config set-context --current --namespace {{namespace}}`

- Switch to another context:

`kubectl config {{[use|use-context]}} {{context_name}}`

- Delete clusters/contexts/users:

`kubectl config {{delete-cluster|delete-context|delete-user}} {{cluster|context|user}}`

- Permanently add custom kubeconfig files:

`export KUBECONFIG="{{path/to/kubeconfig1.yaml}}:{{path/to/kubeconfig2.yaml}}"`
