This section describes how to install and run the original Docker CE on RedHat Linux RHEL 8 by using the official Docker repository for CentOS7:
Note: FOR ALL 3 SERVERS MASTERBOOT WORKERNODE AND PROXYNODE! In the IBM Cloud Private installation referenced in section 4.5.1.
Docker version 18.09.2
- Install the yum-utils package which contains the yum-config-manager utility:
[wasadm@ECMUKDEMO2022 bin]$ su – root

[root@ECMUKDEMO2022 ~]# yum install yum-utils
Updating Subscription Management repositories.
Last metadata expiration check: 3:31:49 ago on Tue 25 Jan 2022 06:28:40 AM PST.
Dependencies resolved.
Enter y at the prompt. - Add the repository for the docker software:
yum-config-manager –add-repohttps://download.docker.com/linux/centos/docker-ce.repo - View the updated repository list and install docker:
yum list docker-ce –showduplicates | sort -r
yum install docker-ce –nobest –skip-broken - Start and enable the docker daemon:
Once docker-ce is installed, the docker daemon can be started and enabled so that it will be also launched automatically at boot.
Note: On the current system, the Red Hat podman equivalent to Docker was already installed so podman replaced docker in the following commands:
[root@ECMUKDEMO2022 ~]# systemctl enable –now podman
Created symlink /etc/systemd/system/multi-user.target.wants/podman.service → /usr/lib/systemd/system/podman.service.
And check that podman is loaded and enabled on a reboot:
[root@ECMUKDEMO2022 ~]# systemctl is-enabled podman
enabled
