Docker Engine

Official Documentation can be found here. Official Docs

Installation​

First you should always update your system. You can do so by running the following command inside a Terminal.

sudo apt update && apt upgrade -y

Now lets check for 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

Adding the Repository​

The following command will setup Dockers 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

Installing Docker Engine​

Time to install Docker.

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

Test the Installation​

You can test that Docker is running using this command.

sudo docker run hello-world
My Tip

I prefer using Docker-Compose(installed with Docker Engine with this tutorial). If you do not have Docker Compose, Install here Docker-Compose.

info

You still need to install the Docker Engine if you wish to use Docker-Compose
