How to Install Docker on CentOS 8

Install Docker on CentOS 8

In this article, we will have explained the necessary steps to install Docker on CentOS 8. Before continuing with this tutorial, make sure you are logged in as a user with sudo privileges. All the commands in this tutorial should be run as a non-root user.

Docker is an open-source project which allows the creation and distribution of applications inside containers, which are standardized environments that can be easily replicated, independently from the host system.

Install Docker on CentOS 8

Step 1. The first command will update the package lists to ensure you get the latest version and dependencies.

sudo dnf install epel-release
sudo dnf update

Step 2. Install Docker on CentOS.

Now, we add the Docker repository:

sudo dnf config-manager --add-repo=

Verify that the repository has been enabled by typing the following dnf command:

$ sudo dnf repolist -v


Repo-id      : docker-ce-stable
Repo-name    : Docker CE Stable - x86_64
Repo-revision: 1567619328
Repo-updated : Mon 11 Nov 2019 05:46:36 PM UTC
Repo-pkgs    : 51
Repo-size    : 1.1 G
Repo-baseurl :
Repo-expire  : 146,600 second(s) (last: Mon 04 Oct 2019 09:46:36 PM UTC)
Repo-filename: /etc/yum.repos.d/docker-ce.repo

Install Docker using the following command:

sudo dnf -y  install docker-ce --nobest

Now we must enable docker service:

sudo systemctl enable --now docker

You can check the Docker service status using the following systemctl command:

sudo systemctl status docker

The output should be similar to the following, showing that the service is active and running:

docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor pres>
   Active: active (running) since Sun 2019-11-11 18:00:45 UTC; 1min 32s ago
 Main PID: 2856 (dockerd)
    Tasks: 24
   Memory: 53.2M
   CGroup: /system.slice/docker.service
           ├─2826 /usr/bin/dockerd -H fd://
           └─2823 containerd --config /var/run/docker/containerd/containerd.tom>

Finally, add your user to the docker group with the command:

sudo usermod -aG docker $USER
