How To Install Docker On Fedora 38

install Docker on Fedora 13

In this short tutorial we will learn how to install Docker on Fedora 38 operating system. At least there are two options to install Docker, namely using OS repository and using source file.

Introduction

In the fast-paced world of software development, efficiency and scalability are paramount. Docker, a revolutionary containerization platform, has emerged as a game-changer, allowing developers to streamline their workflows, enhance collaboration, and deploy applications seamlessly across various environments. In this article, we’ll delve into the world of Docker, exploring its key features, benefits, and providing practical insights for beginners.

What is Docker?

Docker is an open-source platform that automates the deployment of applications inside lightweight, portable containers. These containers encapsulate all the dependencies and configurations needed to run an application, ensuring consistency across different environments.

Key Concepts

  • Containers: Lightweight, standalone, executable packages that include everything needed to run a piece of software.
  • Images: Snapshots of a container, containing the application and its dependencies.
  • Dockerfile: A script defining the steps to create a Docker image.

Advantages of Docker

  1. Portability. Docker containers run consistently across different environments, eliminating the common “it works on my machine” problem. This portability enhances collaboration and accelerates development.
  2. Efficiency. Docker’s lightweight nature ensures optimal resource utilization, allowing for the deployment of more applications on the same hardware than traditional virtualization methods.
  3. Scalability. Docker’s ability to scale applications effortlessly makes it a favorite among developers. Whether you’re handling a small project or a large-scale application, Docker’s scalability is unmatched.

How To Install Docker On Fedora 38

There are two methods of installing Docker, namely: using the Docker repository, installing from the rpm package. However, before the installation process can begin, there are prerequisites that must be met, namely: OS Fedora 38 and no Docker packages installed on the system.

Installing Docker using the RPM Repository

Installing Docker using RPM repository, we need to set up the Docker repository. Then can install and update Docker from the repository. For this purpose we will do following steps :

1. Set up the Repository

To setup Docker repository, we wil use the following command line :

$ sudo dnf -y install dnf-plugins-core
$ sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

Output :

ramansah@bckinfo ~]$ sudo dnf -y install dnf-plugins-core
Fedora 38 - x86_64                                                             386 kB/s |  83 MB     03:39    
Fedora 38 openh264 (From Cisco) - x86_64                                       419  B/s | 2.5 kB     00:06    
Fedora Modular 38 - x86_64                                                     644 kB/s | 2.8 MB     00:04    
Fedora 38 - x86_64 - Updates                                                   124 kB/s |  35 MB     04:46    
Fedora Modular 38 - x86_64 - Updates                                           171 kB/s | 2.1 MB     00:12    
Package dnf-plugins-core-4.4.0-1.fc38.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!
ramansah@bckinfo ~]$ sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

Adding repo from: https://download.docker.com/linux/fedora/docker-ce.repo

1. Install Docker

In this stage, we will install Docker Engine, containerd, and Docker Compose. We will execute the following command lines :

$ sudo dnf update
$ sudo dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Output :

2. Starting Docker

After Docker installation was completed done the Docker daemon will be started. We will submit command lines :

$ sudo systemctl start docker
$ sudo systemctl status docker

Output :

[ramansah@bckinfo ~]$ sudo systemctl start docker
[ramansah@bckinfo ~]$ sudo systemctl status docker

3. Verify Docker Installation

After Docker installation is completed done, then we will verify itu by submitting a command to download a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.

$ sudo docker run hello-world

Output :

[ramansah@bckinfo ~]$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
719385e32844: Pull complete 
Digest: sha256:c79d06dfdfd3d3eb04cafd0dc2bacab0992ebc243e083cabe208bac4dd7759e0
Status: Downloaded newer image for hello-world:latest

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

Share images, automate workflows, and more with a free Docker ID:

We have now successfully installed and started Docker Engine on Fedora 38 operating system.
