 1 | ## Simple kubeconfig switcher
 2 | 
 3 | **Why do I did this project?**
 4 | 
 5 | I know there is the *cool* way of dealing with multiple k8s clusters, by merging the different kube-configs in `~/.kube/config` and use `kubectl config use-context` to switch them. Currently I'm setting up a lot of clusters, with their own kubeconfigs, and I'm getting tired of all that merging.
 6 | 
 7 | Actually, life can be simpler just by rotating that configs around. So I spent that 10 minutes of bashing that project to make my (and maybe your) life easier.
 8 | 
 9 | ## How to install?
10 | 
11 | * clone that project
12 | * put it into a folder behind your $PATH, like `/usr/bin`, `/usr/local/bin` or what ever you want
13 | * you are done...it's simple bash, and does not depend on any lib
14 | 
15 | ## How to use?
16 | 
17 | whenever a wild kubeconfig appears, add it with
18 | 
19 | ```
20 | $ kubeconfig-loader add my-new-cluster /path/to/new/kubeconfig/file
21 | ```
22 | 
23 | proof you have `my-new-cluster` available with
24 | 
25 | ```
26 | $ kubeconfig-loader ls
27 | ```
28 | 
29 | switch to that cluster by
30 | 
31 | ```
32 | $ kubeconfig-loader use my-new-cluster
33 | ```
34 | 
35 | and check it works with
36 | 
37 | ```
38 | $ kubectl get node
39 | ```
40 | 
41 | or any other kubectl related command
42 |
