kubectl-cnf is a simple kubectl plugin that helps switch between current-contexts in multiple kubeconfigs within a terminal tab scope.
If you are working with many clusters that come with their own kubeconfigs, you can use this tool to allow yourself multitask by keeping a dedicated terminal tab for each cluster.
By default, the plugin launches a subshell for the chosen kubeconfig. But you can tweak the plugin to just print export KUBECONFIG=PATH command or copy it to the clipboard instead.

- Run
kubectl krew install cnfor just placekubectl-cnfinto the directory within yourPATH(e.g.~/.local/bin) - Create the
~/.kube/configsdirectory and place your kubeconfigs there (or create symlinks)
The krew version is a simple bash script, but you can grab a go version of the plugin from the releases page.
You can export the following variables to tweak the plugin's behaviour.
| VARIABLE | DEFAULT | DETAILS |
|---|---|---|
KCNF_DIR |
~/.kube/configs |
directory with kubeconfigs |
KCNF_HEIGHT |
40% |
selection menu height |
KCNF_NO_VERBOSE |
0 |
do not print auxiliary messages |
KCNF_NO_SHELL |
0 |
print export KUBECONFIG=PATH to stdout instead of launching a subshell |
KCNF_COPY_CLIP |
0 |
copy export KUBECONFIG=PATH to clipboard instead of launching a subshell |
KCNF_SYMLINK |
0 |
symlink selected kubeconfig to ~/.kube/config instead of launching a subshell |
