4.6.3 Updating of libraries and X-Window installs
For the x-windows GUI, we can install the Linux X-Windows libraries, as follows, in the procedure. See the following link from Pages 40 to 45:

4.6.4 Environment
The following section covers the outline procedure to install the xorg-x11-apps package for xterm on an RHEL 8.0 system.
The xorg-x11-apps package is no longer available in RHEL8.0. (xclock is not supported). Use xterm or any other GUI application to test SSH X11 Forwarding. See Appendix A of the ResearchGate publication:

Conclusion
In this chapter, we described the installation of IBM Software Products on the following system platforms; the Docker Container system with the use and function of the main docker commands; The RedHat OpenShift system; The IBM Cloud Private system covering the installation of IBM Cloud Private 3.2.0 (Community Edition). The download and installation of the RedHat 8.0 operating system disk image on VMware Workstation Pro. The set-up and use of IBM Cloud for on-premises DB2Graph installation.
In the next chapter, the procedure is described for the installation and configuration of IBM software on an IBM Cloud Private Cluster and IBM Cloud.
Points to remember
• The Docker install should be run for the original Docker CE on RHEL 8 by using the official Docker repository for CentOS7 on all three cluster servers for IBM Cloud Private.
• The Red Hat podman equivalent to Docker is already installed so podman replaces docker on the latest Red Hat RHEL 8.x upgrade (all the Docker commands are emulated automatically).
• Red Hat subscription-manager uses port 443 to register the RHEL 8.0 Linux server after naming the server using the hostnamectl so the port 443, firewall port, needs to be open.
• The SSH public key should have already been copied to the other cluster node servers as a prerequisite to running the OpenShift 4.x ISO Boot image file.
• For a standard or Community Edition environment, you can have only one node in the master section.
• If there is a single computer used for multiple nodes in the cluster, the server IP address must be defined in each related node section of the cluster host’s file. (Do not include any server names in this file, just the IP addresses of each server node)
