Step 1 : Update the package index:
$ sudo apt update -y
Step 2 : Install prerequisites:
$ sudo apt install apt-transport-https ca-certificates curl software-properties-common
Step 3 : Add the Docker GPG key:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
Step 4 : Add the Docker APT repository
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Step 5 : Update the package index again:
sudo apt update
Step 6 : Install latest version
$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
Step 7 Start and Enable Docker
Once the installation is complete, we can start and enable the Docker service. Run the following command:
$ sudo systemctl enable --now docker
$ sudo systemctl status docker
Step 7 : Create Docker group
To avoid having to use sudo each time we run Docker, it is recommended to add your user to the Docker group. To create the Docker group, run the following command:
$ sudo groupadd docker
groupadd: group 'docker' already exists
$ sudo usermod -aG docker $USER
$ newgrp docker
$ docker run hello-world
