Install Docker Engine on RHEL 9.x

Introduction

As the official Docker repository for RHEL 9.x has not been updated, So you will face issues while installing it.

In this article I will tell you how to install Docker in RHEL 9.x with an alternate method.

Setting up Docker Repository

If you use the following commands from docker website link https://docs.docker.com/engine/install/rhel/

sudo yum install -y yum-utils
sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/rhel/docker-ce.repo

You might get the following error while trying to set up the official RHEL Docker repository in RHEL 9.x

To fix the above error, try to setup CentOS docker repository in RHEL 9.x by following the commands

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

Installing Docker

Use the following command to install Docker

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

This command installs the docker, but it does not start. So to start docker use the following command

sudo systemctl start docker

To verify Docker installation is successful try running hello-world image.

sudo docker run hello-world

This command runs the container and prints the message and exits.

Conclusion

By setting up CentOS Docker repository in RHEL 9.x you can install the Docker engine on RHEL 9.x.
