How to install Docker on Fedora 31 step by step instructions

  1. Revert back to cgroup v1. Please consider whether this step does not negatively affect your any of the other services running on your system:
    $ sudo dnf install -y grubby
    $ sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0"
    $ sudo reboot
    
  2. Next, step is to enable 3rd-party docker repository:
    $ sudo dnf config-manager --add-repo=https://download.docker.com/linux/fedora/docker-ce.repo

  4. Once the Docker repository is enabled enter the following command to install the docker-ce package:
    $ sudo dnf install docker-ce
    
  5. Start and enable Docker on your Fedora 31 system:
    $ sudo systemctl enable --now docker
    Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
    
  6. Confirm that Docker is up and running:
    $ systemctl enable --now docker
    Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
    [root@localhost ~]# systemctl status docker

  7. Enable regular user to perform Docker administration tasks. First, create the docker group:
    $ sudo groupadd docker
    
    Once the group is created give your user administrative privileges:
    $ sudo usermod -aG docker USERNAME
