How to install docker on Redhat Linux (RHEL) and CentOS? How to setup the docker environment to start the first container to start exploring the container world? In this article, we are going to demonstrate the docker community edition deployment on RHEL/CentOS. We will also launch the Docker containers to test the deployment.

Step 3: Install Docker CE Engine on AlmaLinux 8 or Rocky Linux 8. Now that we've added the Docker repository to our system, we can install Docker-CE, as well as its command-line tool and containerd.io, to manage the container lifecycle of its host system using dnf. $ sudo dnf install docker-ce docker-ce-cli containerd.io. Hi GuysThis video belongs to Docker Installation in RedHat 8 System. I have given Docker repo configuration which is mention below!!!! If you face Any prob. Home » Articles » Linux » Here. Docker: Install Docker on Oracle Linux 8 (OL8) This article demonstrates how to install Docker on Oracle Linux 8 (OL8). RHEL8, and therefore OL8, have switched their focus from Docker and on to Podman for containers, so this installation uses the Docker CE installation from the Docker repository. Installing Docker: Once the repo is configured successfully, we are good to install docker community edition. # yum install docker-ce. Running transaction Installing: libcgroup-0.41-15.el7.x8664 1/11 Installing: pigz-2.3.3-1.el7.centos.x8664 2/11 Installing: audit-libs-python-2.8.1-3.el7.x8664 3/11 Installing: libtool-ltdl-2.4.2-22.el73.

Docker glossary

  • Docker Image: Docker images are the basis of containers. An Image is an ordered collection of root filesystem changes and the corresponding execution parameters for use within a container runtime. An image typically contains a union of layered filesystems stacked on top of each other. An image does not have state and it never changes.
  • Docker container: A container is a runtime instance of a docker image.
  • Docker registry: A Registry is a hosted service containing repositories of images which response to the Registry API. The default registry can be accessed using a browser at Docker Hub or using the docker search command.

Pre-requisites:

1. Docker supports only x86_64 (64-bit architecture). It also required Linux kernel version 3.8 and above. You could verify the system architecture and kernel version using the following command.

2. Ensure that system is installed with following packages.

  • device-mapper-libs
  • device-mapper
  • lvm2-libs
  • lvm2
  • device-mapper-persistent-data
  • yum-utils

If not, please install the missing packages using yum command.

Setting up the Docker Repository:

Install Docker On Redhat Linux 8

Configure the docker repository by pulling the repo file form docker website and save it in /etc/yum.repos.d directory. The following command does all the actions for you.

Note: Docker community edition is not available for RHEL. However, Docker provides the community edition for Centos which also can be installed on RHEL. But it’s unsupported.

Installing Docker:

Once the repo is configured successfully, we are good to install docker community edition.

Install Docker On Redhat Linux 8

You might get following errors on Redhat Enterprise Linux (RHEL)

Error: Package: docker-ce-18.03.1.ce-1.el7.centos.x86_64 (docker-ce-stable)
Requires: pigz
Error: Package: docker-ce-18.03.1.ce-1.el7.centos.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2.9
You could try using –skip-broken to work around the problem
You could try running: rpm -Va –nofiles –nodigest

To fix above mentioned error,

Redhat Linux (RHEL 7) requires extra rpms. Enable the extras RHEL repository. This ensures access to the container-selinux package which is required by docker-ce. It requires a Red hat subscription.

Start the Docker service

Once the installation is done, you need to start the docker service manually.

To start the docker service on startup,

Install Docker On Rhel 8.4

Verify the docker Installation:

The most common way to test the docker is, running image “hello-world” .
