kubel

Emacs extension for controlling Kubernetes with limited permissions.

You can watch how kubel started or read about it.

Features

We now support managing pretty much any resource!

switch context and namespace
show any resource (pods/services/deployments/etc)
highlight a resource by name
copy resource name to clipboard
show and edit resource details
show rollout history for a resource
delete a resource
tail container logs (possibly with -f follow flag)
copy container log command to clipboard
port forward a pod to your localhost
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.

To switch to showing a different resource, use the R command or

M-x kubel-set-resource

This will let you select a resource and re-display the kubel buffer.

Shortcuts

On the kubel screen, place your cursor on a resource

enter => get resource details
h => help popup
C => set context
n => set namespace
K => set kubectl config file
R => set resource
F => set output format
g => refresh
f => set a substring filter for resource name
M-n => jump to the next highlighted resource
M-p => jump to previous highlighted resource
E => quick edit any resource
r => see the rollout history for resource
l => log popup
c => copy popup
k => delete popup
e => exec into pod
p => port forward pod
j => jab deployment to force rolling update

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 switch the resource with R and select "Deployments", then press return with the cursor on the row you wish to edit, edit the buffer, and hit C-c C-c to apply.

Alternatively, you can hit E to then select the resource type and the resource name of what you want to edit.

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.

If you need to switch or set your kubectl config file by setting your KUBECONFIG environment variable, you can use the wrapper function kubel-set-kubectl-config-file or the K shortcut.
