Install Docker and Docker Compose on Linux Fedora

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.

Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

Fedora Linux is a Linux distribution developed by the Fedora Project which is sponsored primarily by Red Hat (an IBM subsidiary) with additional support and sponsors from other companies and organizations. Fedora contains software distributed under various free and open-source licenses and aims to be on the leading edge of open-source technologies. Fedora is the upstream source for Red Hat Enterprise Linux.

Install Docker

To get started with Docker Engine on Fedora, make sure you meet the prerequisites, then install Docker.

Prerequisites

OS requirements

To install Docker Engine, you need the 64-bit version of one of these Fedora versions:

  • Fedora 34

  • Fedora 35

Install using the repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

Set up the repository

Install the dnf-plugins-core package (which provides the commands to manage your DNF repositories) and set up the stable repository.

Install Docker Engine

  1. Install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:
1
[root@fedora ~]# sudo dnf install docker-ce docker-ce-cli containerd.io
  1. Start Docker.
1
[root@fedora ~]# sudo systemctl start docker
  1. Verify that Docker Engine is installed correctly by running the hello-world image.

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Install Docker Compose

On Linux, you can download the Docker Compose binary from the Compose repository release page on GitHub. Follow the instructions from the link, which involve running the curl command in your terminal to download the binaries. These step-by-step instructions are also included below.

Run this command to download the current stable release of Docker Compose:

1
$ sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Apply executable permissions to the binary:

1
$ sudo chmod +x /usr/local/bin/docker-compose

Test the installation.
