k8.bash

k8 is great.md

kubeenv for lazy typers...

Usage

1. Copy the below into your .bash_profile or similar
2. k8 <your-context>, where your-context is the shortcut name you'd like to use
3. gcloud container clusters get-credentials <clustername>
4. Repeat step 3 for each of the k8s contexts you want to have available
5. To use, run k8 <your-context> to change contexts.

k8 has tab-completion for configured contexts, use removek8 <your-envname> to delete a context.

(see kubeenv readme for zsh usage)
