This is just for my own note so that I don’t have to Google around for every time I do this for my own.
Execute the following commands.
sudo apt-get update sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg echo "deb [arch=amd64 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 sudo apt-get update sudo apt-get install docker-ce docker-ce-cli containerd.io sudo usermod -aG docker $USER
This way I just have to copy and paste all the commands listed here to have a running Docker on a Ubuntu host.
To test the Docker installation, execute and make sure the following command executes successfully.
$ docker run hello-world
I am going to take another note below for installing docker compose as well.
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose
To test docker compose installation, make sure the following command executes successfully.
