How to Install Kubernetes on Ubuntu 22.04 on Single Node

Kubernetes is an open-source container orchestration system. It simplifies the automation of software deployment, scaling, and management. Let’s take a look at how to set up Kubernetes on Ubuntu 22.04:

How to Install Kubernetes on Ubuntu 22.04 on Single Node

  1. First, we have to make sure the system packages are up to date:
    sudo apt update
  2. As Kubernetes needs Docker to manage containers, we have to install it with this command:
    sudo apt install docker.io -y
  3. Then, start the Docker service and enable it to run on startup:
    sudo systemctl start docker
    sudo systemctl enable docker
  4. Next, check the status of Docker to confirm it’s running properly:
    sudo systemctl status docker

  5. Now, it is time to add the Kubernetes signing key. So, create a directory for the keyrings:
    sudo mkdir /etc/apt/keyrings

    Then, add the Kubernetes signing key:

    curl -fsSL https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-archive-keyring.gpg
  6. After that, add the Kubernetes repository:
    echo "deb [signed-by=/etc/apt/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
  7. Then, update the package list and install Kubernetes components:
    sudo apt-get update
    sudo apt install kubeadm kubelet kubectl -y
  8. Furthermore, we can prevent automatic updates that may disrupt your setup by marking the Kubernetes packages:
    sudo apt-mark hold kubeadm kubelet kubectl
  9. Finally, check the installed Kubernetes version:
    kubeadm version
  10. To ensure the cluster is set up correctly, check the nodes and pods:
    kubectl get nodes
    kubectl get pods --all-namespaces

Following the above steps, we can install and configure Kubernetes on our Ubuntu 22.04 system.
