k8s-configuration-manager

Manage in a better way multiple kubernetes config.

This tiny cli creates in your home directory the folder .kcm, to store multiples .kube configs. So you can switch configurations of kubernetes as easiest ever. Also it stores the last config used in the file .kcm/kcm_config.json, and makes a backup in case .kube are not empty.

Install

npm i -g k8s-config-management

Commands

$ ./bin/kcm -h

  Usage: kcm [options] [command]

  Multiple k8s configuration manager

  Options:

    -V, --version                    output the version number
    -h, --help                       output usage information

  Commands:

    add|a <fileOrFolderPath> [name]  Copy contained config or file config with the specified with the folder name under 'kcm' folder
    use [name]                       Put the config you want in `.kube` to use it with `kubectl`
    now                              Shows actual config
    ls                               Show stored config in `.kcm`

• add file_or_folder_path name: Add file_or_folder_path to the .kcm directory with folder name specified. If you dont put name it uses default

• use name: Copy the name config to the .kube directory. If you dont use a name it uses default.

• now: Show configuration that you are using, it is stored in .kcm/kcm_config.json file

• ls: Show a list of the predefined configurations, basically a ls -l of the .kcm excluding files.

Example

As an example imagine you have 2 kubernetes configurations: client-1 and personal.

> tree -L 1 ~/.kcm

/Users/USER/.kcm
├── ...
└── kcm_config.json

Then you add both files with kcm

> kcm add ./kube-folder-of-client-1 client-1
> tree -L 1 ~/.kcm
/Users/USER/.kcm
├── client-1
└── kcm_config.json

> kcm add ./kube-folder-of-personal personal
/Users/USER/.kcm
├── personal
├── client-1
└── kcm_config.json

Now you already have both configuration to be managed by kcm. Now type kcm use personal or kcm use client-1 to copy the content to your .kube and here we go, your kubectl now use the config you want.

Then you can use kcm use client-1 or kcm use personal to make your .kube change. Easy!

Notes

When you use kcm use ... it always make a backup of your actual config (but only stores 1 backup, so be care about it)

Its a simple tool, if you copy manually to your .kube there is no way that kcm will know about it.
