Setting up on Docker
This page covers the installation of Docker on Debian and a quickstart with compose.
We will assume your Debian machine is a blank state configured with the fastest mirrors.
Setting up the base Docker
Everything there needs to be run as room (you can use
sudo for most commands).
Update your system with
apt update and then install prerequisites
apt install ca-certificates curl gnupg lsb-release.
Add the Docker PGP key:
mkdir -p /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
And then add the repo:
echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \ $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
Now, update and install Docker itself
apt update; apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin
This will install the base of Docker but also the
docker-compose plugin that we will use later.
Now enable and start Docker and you’re all set:
systemctl enable docker systemctl start docker
Create a file named
docker-compose.yml and inside:
version: "3.9" services: hello: image: hello-world
Now you can run
docker compose up and see the hello world.
