Production-identical environments for development: Developers use open source tools like Kubernetes to provision individual development environments. Coding against virtual, disposable replicas of production helps you get more work done.

 

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
