Install Docker on Ubuntu Server

Note: Before proceeding with the installation, it's recommended to perform some post-installation steps on your server. You can find the details in this gist.

Run the following command to uninstall all conflicting packages:

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

Set up Docker's apt repository.

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

Install the Docker packages.

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

Add your user to the Docker group:

sudo usermod -aG docker ${USER}

Create the Docker group (if it doesn't exist):

sudo groupadd docker

Activate the new group:

newgrp docker

Verify that the installation is successful by running the hello-world image:

docker run hello-world

To ensure the Docker service starts on boot by default:

sudo systemctl enable docker.service
sudo systemctl enable containerd.service
