Changing the default k9s/Kubernetes context

Question

I have 3 contexts set up in k9s (context1, context2, context3). I know I can change the context within k9s by typing :context but how do I change the default context that loads when I open k9s from context3 to context1?

Answer 1

You can set the default context via kubectl:

kubectl config use-context context1

This will update the default context in your KUBECONFIG, what is the base for k9s.

From your commandline (not inside k9s) you should be able to use kubectl as k9s needs it.

1. get a list of the contexts: kubectl config get-contexts
2. set the default contexts: kubectl config use-context <context>

Example shell

$ kubectl config get-contexts
CURRENT   NAME       CLUSTER   AUTHINFO    NAMESPACE
          dev        dev       dev    
*         test       test      test
          my-context idk       idk
$ kubectl config use-context my-context
Switched to context "my-context".
$ kubectl config get-contexts
CURRENT   NAME       CLUSTER   AUTHINFO    NAMESPACE
          dev        dev       dev    
          test       test      test
*         my-context idk       idk
$

Now you see the star on CURRENT on a different value

I think you can change the k9s config.yml file, this link can help you understand better https://k9scli.io/topics/config, normally it is defined like this example:

k9s:
  refreshRate: 2
  maxConnRetry: 5
  enableMouse: false
  headless: false
  logoless: false
  crumbsless: false
  readOnly: false
  noExitOnCtrlC: false
  noIcons: false
  logger:
    tail: 100
    buffer: 5000
    sinceSeconds: 60
    fullScreenLogs: false
    textWrap: false
    showTime: false
  **currentContext**: arn:aws:eks:us-east-1:ID:cluster/account-name
  **currentCluster**: arn:aws:eks:us-east-1:ID:cluster/account-name
