kpad

A Kubernetes manifests editor.

Kpad is a simple multiplatform terminal editor born to edit kubernetes declarative manifest yaml files.

It has syntax highlighting and provides a handy auto-complete that pops up a list of possible context-aware fields at the cursor position.

To show the auto-complete list, press CTRL+SPACE on Linux/Mac or press CTRL+K on Windows

autocompletion configuration

If you work using the plain "kubectl" CLI from your console, then kpad should work on the fly.

Behind the scenes, kpad calls "kubectl explain" to populate the auto-complete list, so it is also aware of your custom kubernetes objects in your cluster, and provides autocompletion for them.

If in your cluster you use something different from the plain "kubectl" CLI command, you can configure it in kpad launching kpad -c and change the configuration there.

For example if you use "MicroK8s", then launch kpad -c and change like this:

kubectl: microk8s kubectl

kpad honours your KUBECONFIG

If you wish to use kpad to edit kubernetes manifests from other clusters, and you have the "kubeconfig" file for those clusters, you can point to that cluster by setting the KUBECONFIG environment variable to the path of that file, and then kpad would connect to that cluster to provide auto-completion.

make kpad the default kubernetes manifests editor

To make kpad your default kubernetes manifests editor, set the "KUBE_EDITOR" environment variable to the path where kpad is. In linux, for example: export KUBE_EDITOR=/<path>/<to>/kpad

Kpad is still work-in-progress, although it is pretty stable and quite fast.

• It is written in go.
• It's pretty lightweight.
• It compiles for Mac, Win, Linux.
• It also supports wide characters (2x width on the terminal).
• It even runs on my phone.
