Quick docker installation reference.
This is a quick reference to the docker installation steps to take, but you can always check the full installation guide on the official docker website.

Set up the repository

  • Update the apt package index and install packages to allow apt to use a repository over HTTPS:
    sudo apt-get update
    sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
  • Add Docker’s official GPG key:
    curl -fsSL | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
  • Use the following command to set up the stable repository
    echo \
    "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] \
    $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker Engine

  • Update the apt package index, and install the latest version of Docker Engine and containerd:
    sudo apt-get update

  • Verify that Docker Engine is installed correctly by running the hello-world image.
    sudo docker run hello-world
  • Add User to Docker Group
