+title: Kubectx
+homepage: https://github.com/ahmetb/kubectx
+tagline: |
+  kubectx: kubectx is a utility to manage and switch between kubectl contexts.
+---
+
+### Updating `kubectx`
+
+`webi kubectx@stable`
+
+Use the `@beta` tag for pre-releases.
+
+## Cheat Sheet
+
+> `kubectx` kubectx helps you switch between Kubernetes clusters back and forth
+
+To run kubectx:
+
+```bash
+kubectx
+```
+
+### Command line arguments
+
+```bash
+USAGE:
+  kubectx                   : list the contexts
+  kubectx <NAME>            : switch to context <NAME>
+  kubectx -                 : switch to the previous context
+  kubectx -c, --current     : show the current context name
+  kubectx <NEW_NAME>=<NAME> : rename context <NAME> to <NEW_NAME>
+  kubectx <NEW_NAME>=.      : rename current-context to <NEW_NAME>
+  kubectx -d <NAME>         : delete context <NAME> ('.' for current-context)
+                              (this command won't delete the user/cluster entry
+                              that is used by the context)
+  kubectx -u, --unset       : unset the current context
+```
