Tmux Kubernetes Context

Shows your current Kubernetes context and namespace

Installation

Dependencies

This assumes that you have kubectl installed and have at least one context in your ~/.kube/config or wherever your KUBECONFIG points.

jq is required for parsing the output.

Installation with Tmux Plugin Manager (recommended)

Add plugin to the list of TPM plugins in .tmux.conf set -g @plugin 'sudermanjr/tmux-kube'

Hit prefix + I to fetch the plugin and source it.

If format strings are added to status-right or status-left they should be visible, assuming you have the necessary dependencies.

Manual Installation

Clone the repo:

    $ git clone https://github.com/sudermanjr/tmux-kube ~/clone/path

Add this line to ~/.tmux.conf

    run-shell ~/clone/path

Reload TMUX environment:

    $ tmux source ~/.tmux.conf

If format strings are added to status-right or status-left they should be visible, assuming you have the necessary dependencies.

Usage

Add #{kube_cluster}, or #{kube_namespace} to your status line to get current context info.

Basic Example:

    set -g status-right '#{kube_cluster}:#{kube_namespace}'

You can set which clusters are prod/stage/dev inside your tmux.conf, and use that to colorize the output.

Example:

    set -g @kube_prod_clusters 'whatsit'
    set -g @kube_stage_clusters 'whosit'
    set -g @kube_dev_clusters  'thatsit'

    set -g status-left '#{kube_fg} K8S-#{kube_cluster}:#{kube_namespace}'

Changing Colors:

    set -g @kube_color_dev '#[fg=colour32]'
    set -g @kube_color_stage '#[fg=colour221]'
    set -g @kube_color_prod '#[fg=colour196]'
