  1. install Docker and docker-compose

    apt-get update
apt-get install docker docker.io containerd docker-compose

  2. create the jobs directories. All docker compose files will be under /home/jobs/scripts/by-user/root/docker/${project_name}

    mkdir -p /home/jobs/scripts/by-user/root/docker
chmod 700 /home/jobs/scripts/by-user/root/docker

  3. make sure that Docker containers uses network addresses from a known range. Edit the Docker daemon file

    /etc/docker/daemon.json#
    1{
2  "default-address-pools":
3  [
4   {"base": "172.16.0.0/12", "size": 24}
5  ]
6}

  4. restart Docker

    systemctl restart docker.service docker.socket

  5. check that the Docker daemon is still working

    systemctl status docker docker.socket

Nota

If you installed docker-compose using the root user from pip you must first manually remove docker-compose and all its dependencies from /usr/local/lib/python3.*/dist-packages/ using pip uninstall as command.
