# sample-cli-plugin
This repository implements a single kubectl plugin for switching the namespace
that the current KUBECONFIG context points to. In order to remain as indestructive
as possible, no existing contexts are modified.
**Note:** go-get or vendor this package as `k8s.io/sample-cli-plugin`.
This particular example demonstrates how to perform basic operations such as:
* How to create a new custom command that follows kubectl patterns
* How to obtain a user's KUBECONFIG settings and modify them
* How to make general use of the provided "cli-runtime" set of helpers for kubectl and third-party plugins
It makes use of the genericclioptions in [k8s.io/cli-runtime](https://github.com/kubernetes/cli-runtime)
to generate a set of configuration flags which are in turn used to generate a raw representation of
the user's KUBECONFIG, as well as to obtain configuration which can be used with RESTClients when sending
requests to a kubernetes api server.
## Details
The sample cli plugin uses the [client-go library](https://github.com/kubernetes/client-go/tree/master/tools/clientcmd) to patch an existing KUBECONFIG file in a user's environment in order to update context information to point the client to a new or existing namespace.
In order to be as non-destructive as possible, no existing contexts are modified in any way. Rather, the current context is examined, and matched against existing contexts to find a context containing the same "AuthInfo" and "Cluster" information, but with the newly desired namespace requested by the user.
## Purpose
This is an example of how to build a kubectl plugin using the same set of tools and helpers available to kubectl.
## Running
```sh
# assumes you have a working KUBECONFIG
$ go build cmd/kubectl-ns.go
# place the built binary somewhere in your PATH
$ cp ./kubectl-ns /usr/local/bin
# you can now begin using this plugin as a regular kubectl command:
# update your configuration to point to "new-namespace"
$ kubectl ns new-namespace
# any kubectl commands you perform from now on will use "new-namespace"
$ kubectl get pod
NAME READY STATUS RESTARTS AGE
new-namespace-pod 1/1 Running 0 1h
# list all of the namespace in use by contexts in your KUBECONFIG
$ kubectl ns --list
# show the namespace that the currently set context in your KUBECONFIG points to
$ kubectl ns
```
## Use Cases
This plugin can be used as a developer tool, in order to quickly view or change the current namespace
that kubectl points to.
It can also be used as a means of showcasing usage of the cli-runtime set of utilities to aid in
third-party plugin development.
## Cleanup
You can "uninstall" this plugin from kubectl by simply removing it from your PATH:
$ rm /usr/local/bin/kubectl-ns
## Compatibility
HEAD of this repository will match HEAD of k8s.io/apimachinery and
k8s.io/client-go.
## Where does it come from?
`sample-cli-plugin` is synced from
https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/sample-cli-plugin.
Code changes are made in that location, merged into k8s.io/kubernetes and
later synced here.
