How to Install Docker CE and Docker-Compose on CentOS 8

Docker is a set of Platform as a Service (PaaS) products that uses operating system level virtualizations to deliver software in the form of containers. Docker CE (Community Edition) is the strip down version of Docker EE (Enterprise Edition). Docker CE is free and open source and distributed under Apache License 2.0.

In Red Hat Enterprise Linux (RHEL) 8 / CentOS 8, Support of Docker has been removed by the vendor. Whereas a new containerization platform libpod (Podman’s Container Management Library) has been introduced inplace of Docker.

However, we can still install Docker and it’s dependencies on CentOS 8 / RHEL 8 from third party yum repositories.

In this article, we are installing Docker CE and docker-compose on CentOS 8.


  • You must have Alibaba Cloud Elastic Compute Service (ECS) activated and verified your valid payment method. If you are a new user, you can get $450 — $1300 worth in Alibaba Cloud credits for your new account. If you don’t know how to setup your ECS instance, you can refer to this tutorial or quick-start guide.
  • A domain name registered from Alibaba Cloud. If you have already registered a domain from Alibaba Cloud or any other host, you can update its domain nameserver records.
  • Domain name must be pointed to your Alibaba Cloud ECS’s IP address
  • Access to VNC console in your Alibaba Cloud or SSH client installed in your PC
  • Set up your server’s hostname and create a user with root privileges.

Environment Specification

We have configured a CentOS 8 virtual machine with following specifications.

  • CPU — 3.4 Ghz (2 cores)
  • Memory — 2 GB
  • Storage — 40 GB
  • Operating System — CentOS 8.0
  • Hostname —
  • IP Address —

Adding Docker CE yum Repository on CentOS 8:

Connect with using ssh as root user.

Docker CE is available to download from Docker’s Official Website However, we can also install it from Docker CE yum repository.

Add Docker CE yum repository using dnf command.

[root@docker-01 ~]# dnf config-manager --add-repo=
Adding repo from:

Build cache for Docker yum repository.

[root@docker-01 ~]# dnf makecache
CentOS-8 - AppStream 7.0 kB/s | 4.3 kB 00:00
CentOS-8 - Base 2.2 kB/s | 3.9 kB 00:01
CentOS-8 - Extras 1.7 kB/s | 1.5 kB 00:00
Docker CE Stable - x86_64 6.5 kB/s | 21 kB 00:03
Metadata cache created.

Installing Docker CE on CentOS 8:

After addition of Docker CE yum repository, we can now easily install Docker CE on CentOS 8 by using a dnf command.

Docker CE requires–3 (or later) package, which is blocked in CentOS 8. Therefore, we have to use an earlier version of package.

Install docker-ce with an earlier version of using following command.

[root@docker-01 ~]# dnf -y install --nobest docker-ce

Docker CE has been installed on CentOS 8.

Create a Container using Docker in CentOS 8:

Let’s put Docker into action by creating a simple container.

For this purpose, we are using official image of Alpine Linux from Docker Hub.

[root@docker-01 ~]# docker search alpine --filter is-official=true
alpine A minimal Docker image based on Alpine Linux⦠5945 [OK]

Pull Alpine Linux image from Docker Hub.

[root@docker-01 ~]# docker pull alpine
Using default tag: latest
latest: Pulling from library/alpine
e6b0cf9c0882: Pull complete
Digest: sha256:2171658620155679240babee0a7714f6509fae66898db422ad803b951257db78
Status: Downloaded newer image for alpine:latest

List locally available docker images.

[root@docker-01 ~]# docker images
alpine latest cc0abc535e36 23 hours ago 5.59MB

Create and run a container using Alpine Linux image.

[root@docker-01 ~]# docker run -it --rm alpine /bin/sh
/ # cat /etc/os-release
NAME="Alpine Linux"
PRETTY_NAME="Alpine Linux v3.11"
/ # uname -a
Linux c0089c037e24 4.18.0-80.11.2.el8_0.x86_64 #1 SMP Tue Sep 24 11:32:19 UTC 2019 x86_64 Linux
/ # exit

Installing Docker-compose on CentOS 8:

Additionally, we are installing docker-compose on our CentOS 8 server, so we can create and run multiple containers as a single service.

Download docker-compose package from GitHub.

[root@docker-01 ~]# curl -L`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 617 0 617 0 0 546 0 --:--:-- 0:00:01 --:--:-- 546
100 16.2M 100 16.2M 0 0 184k 0 0:01:29 0:01:29 --:--:-- 276k

Grant execute permissions to docker-compose command.

[root@docker-01 ~]# chmod +x /usr/local/bin/docker-compose

Check docker-compose version.

[root@docker-01 ~]# docker-compose version
docker-compose version 1.25.1-rc1, build d92e9bee
docker-py version: 4.1.0
CPython version: 3.7.4
OpenSSL version: OpenSSL 1.1.0l 10 Sep 2019

We have successfully installed Docker CE and Docker-Compose on CentOS 8. We have only explored the installation of Docker CE here
