Useful kubernetes utilities

kubecm

kubecm is called kubernetes config manager or kubernetes config merger.

Why this utility is born?

If you download the kubeconfig via ibmcloud cli ibmcloud ks cluster config CLUSTER_NAME, you can export only one kubernetes config.

kubectx helps you switch among multiple clusters, but you cannot export multiple kubernetes configs easily for IBM kubernetes service.

So this utility helps you manage and merge KUBECONFIG downloaded from IBM kubernetes service.

Before you begin

This utility can use only for Mac OS. It's not validated in other OS(Windows, Linux).

I recommend to install kubectx, kube-ps1, k9s to operate multi cluster easily.

$ brew install kubectx
$ brew install kube-ps1
$ brew install derailed/k9s/k9s

Installation

for example:

sudo git clone https://github.com/zodiac12k/kubeutils /opt/kubeutils
sudo ln -s /opt/kubeutils/kubecm /usr/local/bin/kubecm

If you want to reload automatically KUBECONFIG when your terminal session open: For zsh:

echo "source kubecm -r" >> ~/.zshrc
source ~/.zshrc

For bash:

echo "source kubecm -r" >> ~/.bashrc
source ~/.bashrc
