Powerline Kubernetes

A Powerline segment to show the current Kubernetes context.

Requirements

• kubectl
• kubernetes Python API.

Installation

Installing the Kubernetes segment can be done with pip:

$ pwd
/home/user/powerline-kubernetes/

$ pip3 install -e .

If you distribution doesn't allow for 'global' pip installation then modify config.json, typically: .config/powerline/config.json

{
    "common": {
        "paths": ["~/your/location/powerline-kubernetes"]
    }
}

The Kubernetes segment uses a couple of custom highlight groups. You'll need to define those groups in your colorscheme, for example in .config/powerline/colorschemes/default.json:

{
  "groups": {
    "kubernetes_cluster":         { "fg": "gray10", "bg": "darkestblue", "attrs": [] },
    "kubernetes_cluster:alert":   { "fg": "gray10", "bg": "darkestred",  "attrs": [] },
    "kubernetes_namespace":       { "fg": "gray10", "bg": "darkestblue", "attrs": [] },
    "kubernetes_namespace:alert": { "fg": "gray10", "bg": "darkred",     "attrs": [] },
    "kubernetes:divider":         { "fg": "gray4",  "bg": "darkestblue", "attrs": [] }
  }
}

Then you can activate the Kubernetes segment by adding it to your segment configuration. To find powerline configuration refer to https://powerline.readthedocs.io/en/master/configuration.html

Example shell powerline: .config/powerline/themes/shell/default.json:

{
    "function": "powerline_kubernetes.kubernetes",
    "priority": 30,
    "args": {
        "show_kube_logo": true,
        "show_cluster": true,
        "show_namespace": true,
        "show_default_namespace": false,
        "alerts": [
          "live",
          "cluster:live"
        ]
    }
}

By default the segment will look for the Kubernetes config variable KUBECONFIG, if not present then the segment will not be displayed.
