You can read lots of blogs about this. This is the simple minimal version 🙂

Assuming you’re doing everything as root, but if you aren’t then prefix these commands with sudo as appropriate for your environment.

dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
dnf install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
systemctl enable --now docker

That’s it. Done. Now if you want to allow non-root users to use docker.

 usermod -aG docker user   # user is the non-root user you want to be able to use docker

docker-compose stopped working?

The symptom is when using the pip3 (python) version of docker compose you get :

kwargs_from_env() got an unexpected keyword argument ‘ssl_version’

Docker’s SDK for Python v7.0.0+ isn’t compatible with docker compose v1, which the python version of docker compose provides. To continue using the python version of docker-compose, ie docker compose v1, downgrade the docker SDK for python to v6.1.3.

However, as the Python version is deprecated, I’ve personally switched to docker compose v2, a golang implementation and sub-option of the Docker command.

docker compose version
Docker Compose version v2.21.0

If you still want to use the python version of docker-compose you’ll need to downgrade the docker sdk for python to version 6.1.3.

pip3 list | egrep docker
docker                    7.0.0
pip3 install docker==6.1.3
Collecting docker==6.1.3
.
