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

Sample docker-compose

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.
