# kubectl

## Installation
### Install on Debian Linux
```
sudo apt install -y apt-transport-https ca-certificates curl gnupg
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.32/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
sudo chmod 644 /etc/apt/keyrings/kubernetes-apt-keyring.gpg # allow unprivileged APT programs to read this keyring
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.32/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo chmod 644 /etc/apt/sources.list.d/kubernetes.list   # helps tools such as command-not-found to work correctly
sudo apt update
sudo apt install -y kubectl
```

### Shell completion
Source the `kubectl completion bash` in the ~/.bashrc file on every login. A simple line which does it after pasting into CMd:
```
echo 'source <(kubectl completion bash)' >> ~/.bashrc
```
