kubel

Emacs extension for controlling Kubernetes with limited permissions.

Features

This is mostly pod management for now. More may come.

• switch context and namespace
• show pods
• get pod details
• tail container logs (possibly with -f follow flag)
• copy pod name to clipboard
• copy container log command to clipboard
• port forward a pod to your localhost
• describe and live edit a resource (deployment,service,job,ingress,configmap)
• show rollout history for a resource
• highlight a pod by name
• exec into a pod using tramp

Installation

Get it from Melpa, or copy and load the kubel.el file.

If you want to have the evil compatibility package, get it from Melpa as well or load the kubel-evil.el file.

Usage

To list the pods in your current context and namespace, call

M-x kubel

To set said namespace and context, respectively call

M-x kubel-set-namespace
M-x kubel-set-context

Note that namespace will autocomplete but not context, this is because I interact with kubernetes through a user who does not have permissions to list namespaces.

Shortcuts

On the kubel screen, place your cursor on the pod

enter => get pod details
h => help popup
C => set context
n => set namespace
g => refresh pods
p => port forward pod
e => exec into pod
d => describe popup
l => log popup
c => copy popup
k => delete pod
j => jab deployment to force rolling update
f => set a substring filter for pod name
r => see the rollout history for resource

Editing a resource

After describing a resource in YAML format, you can edit the buffer and hit C-c C-c to apply your changes.

For example, if you want to edit a deployment, you can hit the key sequence d -y d, then select your deployment, edit the buffer, and hit C-c C-c to apply.

Customize

By default, kubel log tails from the last 100 lines, you can change the kubel-log-tail-n variable to set another line number.
