Easier way to work with multiple Kubernetes clusters.

When working with multiple Kubernetes clusters its painful to switch context using kubectl or kubectx. There are also possibilities of making unintentional changes.

kube-tmuxp solves this by using one preconfigured tmux session per Kubernetes cluster. Each tmux session contains only one Kubernetes context thus preventing accidental context switching inside a session. Contexts can be switched by switching tmux sessions. For example: [tmux prefix] + S.

Given a config similar to config.sample.yaml, kube-tmuxp generates:

• kube config (Kubernetes context) for each Kubernetes cluster under ~/.kube/configs
• tmuxp config for each Kubernetes cluster under ~/.tmuxp

The generated tmuxp configs are used to start preconfigured tmux sessions.

• gcloud
• kubectl
• tmux
• tmuxp

• Clone the repo

  git clone https://github.com/arunvelsriram/kube-tmuxp.git
  

• Setup virtualenv

  virtualenv --python=python3.6 venv
  source venv/bin/activate
  pip install -r requirements.txt
  

• Copy the sample config (config.sample.yaml)

  cp config.sample.yaml config.yaml
  

• Add your clusters to the copied config

• Generate kube configs and tmuxp configs

python kube_tmuxp.py config.yaml

tmuxp load my-context-name

Now you will be inside a tmux session preconfigured with Kubernetes context my-context-name.
