NodeShell

Overview

By enabling the nodeShell feature gate for a given context, K9s allows you to shell into your cluster nodes. Once enabled, you will have a new s for shell menu option while in node view. K9s will launch a pod on the selected node using a special k9s_shell pod. Furthermore, you can refine your shell pod by using a custom docker image preloaded with the shell tools you love. By default k9s uses a BusyBox image, but you can configure it as follows:

Work in progress... Options and layout may change in future K9s releases as this feature solidifies.

Example

# $XDG_CONFIG_HOME/k9s/config.yaml
k9s:
  ...
  # Customize your shell pod configuration here. This will be used by all your clusters.
  shellPod:
    image: cool_kid_admin:42
    namespace: default
    limits:
      cpu: 100m
      memory: 100Mi
  ...

Then unable to feature gate in your blee context configuration.

# $XDG_DATA_HOME/k9s/clusters/clusterX/blee/config.yaml
k9s:
  cluster: clusterX
  readOnly: false
  namespace:
    active: kube-system
    lockFavorites: false
    favorites:
    - all
    - kube-system
    - default
  view:
    active: pod
  featureGates:
    nodeShell: true # => enable nodeShell for this context. Defaults to false
  portForwardAddress: localhost
