Installing Docker on RHEL 9: A Step-by-Step Guide

Introduction: Docker, a leading platform for containerization, has revolutionized the way applications are developed, shipped, and deployed. In this blog, we will walk you through the process of installing Docker on RHEL 9, enabling you to take advantage of the power of containerization. Let's get started!

Step 1: Removing Older Docker Versions Before we proceed, ensure that older versions of Docker, such as docker or docker-engine, are uninstalled along with associated dependencies. Use the following command to do so:

sudo yum remove docker-ce docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine

Step 2: Setting up the Docker Repository Next, we'll set up the Docker repository on RHEL 9. First, install the yum-utils package using the following command:

sudo yum install -y yum-utils

Then, add the Docker repository to your system:

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Step 3: Installing Docker Engine With the repository set up, it's time to install the Docker engine and other essential components:

sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Step 4: Starting Docker Services Now that Docker is installed, let's start the Docker services:

sudo systemctl start docker

Step 5: Testing Docker Installation Finally, let's test our Docker installation by running a simple container:

docker run hello-world

Conclusion: Congratulations! You have successfully installed Docker on RHEL 9. With Docker, you can easily create, deploy, and manage containers, making the process of application development and deployment more efficient and scalable. Now, you are all set to dive into the world of containerization and unlock the full potential of Docker for your projects. Happy containerizing! #Docker #RHEL9 #Containerization #DevOps #TechTutorial
