kubenv

kubenv is a tool to ease the management of multiple kubernetes cluster.

Features:

• Merge different kubeconfig files from different path into a single big kubeconfig
• Switch between kubernetes context
• Execute a command using either a single or mutliple contexts

Install

Grabe the latest release in github release or build it by yourself:

go get https://github.com/mqllr/kubenv

Usage

Get started by picking up your kubeconfig files:

kubenv sync -a=false -m=exec --command="cat /path/to/kubeconfig"
▸ Start the synchronization of kubeconfig file into /home/john/.kube/config ...

Which is equivalent to:

kubenv sync -a=false -m=local --path="/path/to/kubeconfig"
▸ Start the synchronization of kubeconfig file into /home/john/.kube/config ...

And also:

kubenv sync -a=false -m=glob --glob="path/to/kubeconfig"
▸ Start the synchronization of kubeconfig file into /home/john/.kube/config ...

Then you can change your default context by using the use-context

kubenv use-context

or execute a command against a single or multiple contexts:

kubenv with-context

The CLI uses https://github.com/AlecAivazis/survey to navigate between contexts. If you prefer to use j/k to go down or up, press esc:

The user can also press esc to toggle the ability cycle through the options with the j and k keys to do down and up respectively.

Bonus

Want the CLI to be part of kubectl?
