How to install Kubernetes...

Debian

Make sure docker is installed

sudo docker --version
sudo systemctl start docker
sudo systemctl status docker
sudo apt-get install curl -y
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add
curl -s https://api.github.com/repos/kubernetes-sigs/kind/releases/latest| grep browser_download_url | grep kind-linux-amd64 | cut -d '"' -f 4  | wget -qi -
chmod a+x kind-linux-amd64
sudo docker ps
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl"
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl.sha256"
echo "$(cat kubectl.sha256)  kubectl" | sha256sum --check
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
kubectl version --client
kubectl version --client --output=yaml
sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl gnupg
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.30/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:/v1.30/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.30/deb/ /
sudo chmod 644 /etc/apt/sources.list.d/kubernetes.list   # helps tools such as command-not-found to work correctly
sudo apt-get install -y kubectl
