A Powerline segment for showing the status of current Kubernetes context.

It will show any or all of:
You can also:
Toggle on or off the powerline-k8sstatus segment using an environment variable which can easily be mapped to a function in your ~/.profile file.
Define certain contexts or namespaces to be colored differently for alerting purposes. For instance, you can have your production context or kube-system namespace showing up in bright red or solarized yellow respectively.
The K8Sstatus segment requires kubectl. It can be installed following the instructions here.
pip install powerline-k8sstatus
The K8Sstatus 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": {
"k8sstatus": {
"fg": "brightestorange",
"bg": "gray2",
"attrs": []
},
"k8sstatus:alert": {
"fg": "white",
"bg": "solarized:red",
"attrs": [
"bold"
]
},
"k8sstatus_namespace": {
"fg": "gray10",
"bg": "darkestblue",
"attrs": []
},
"k8sstatus_namespace:alert": {
"fg": "darkestred",
"bg": "solarized:yellow",
"attrs": []
},
"k8sstatus_user": {
"fg": "white",
"bg": "green",
"attrs": []
},
"k8sstatus_version": {
"fg": "white",
"bg": "mediumorange",
"attrs": []
},
"k8sstatus:divider": {
"fg": "white",
"bg": "mediumorange",
"attrs": []
}
}
}
Then you can activate the K8Sstatus segment by adding it to your segment configuration,
for example in .config/powerline/themes/shell/default.json
:
{
"function": "powerline_k8sstatus.k8sstatus",
"priority": 50,
"args": {
"show_namespace": true,
"show_user": true,
"show_version": true,
"context_alert": [
"minikube",
"production"
],
"namespace_alert": [
"kube-system",
"production"
]
}
}
context_alert
arguments will be outlined in the segment by a different colour.namespace_alert
arguments will be outlined in the segment by a different colour. Note that default
namespace won't be shown and as result not colorized.Reload powerline running powerline-daemon --replace
to load the new settings.
By default powerline-k8sstatus will display the Kubernetes status segment context. It can be disabled temporarily if the environment variable POWERLINE_K8SSTATUS
is set to 0
. One way to do this would be with a simple function, such as putting this k8sstatus
function in your ~/.bash_profile
:
k8sstatus() {
if [[ $POWERLINE_K8SSTATUS = "0" ]]; then
unset POWERLINE_K8SSTATUS
else
export POWERLINE_K8SSTATUS=0
fi
}
Toggle showing your Kubernetes segment in powerline by just typing k8sstatus
in your terminal
