WARNING: These instructions are for test environments only and not for production environments. This example uses bare minimum specifications for bare minimum test use.

NOTE: These instructions are provided as a courtesy. If you have issues, do not open a case, but rather use our forum to ask questions. These instructions demo one way to set up a testing environment, there are many ways that are documented by Red Hat.

Gateway Host
Server to contain the firewall, router, and DHCP (for DNS use).
1. Download PFSense and upload it to VSphere
  Note: If on a shared system it might already be uploaded
2. In VSphere, expand the CD/DVD menu for the gateway host
3. Select Datastore ISO File and check the Connected box
4. Click Browse and navigate to the PFSense ISO
5. Select connect at Power On
6. Select OK
7. Power on the Virtual Machine and make it boot from the CD/DVD
8. Configure IP addresses for WAN and LAN
9. Open a browser and open the PFSense WebUI at https://{PFSense IP}
10. Login with defaults user admin and password pfsense
11. Click Firewall, then NAT
12. Select Outbound
13. Select Manual Outbound NAT rule generation
14. Click Services, then DHCP Server
15. Select Enable DHCP server
16. Configure your LAN Range
17. Configure the DNS servers
18. Type in the Domain name
  WARNING: Assign a cluster name and a domain that is consistent. These settings cannot be changed later or the cluster might stop working.
19. TFTP Server put the Services host IP
20. Select Enables network booting
21. Next Server put the Services host IP
22. Default BIOS file name, type pxelinux0
23. Root path, type /var/lib/tftpboot
24. Configure static IP addresses for the MAC Address of the Bootstrap, Controllers, and Worker VMs
25. Select Save

Services Host
Used for BIND, Load Balancer, network repository, FTP server, and NFS server.
1. Expand the CD/DVD menu
2. Select Datastore ISO File and check the Connected box
3. Click Browse and navigate to the CentOS or RHEL ISO
4. Select connect at Power On
5. Select OK
6. Power on the virtual machine and make it boot from the CD/DVD
7. Follow installation prompts
8. Once installation is completed login
9. mkdir -p /root/openshift-upi
10. mkdir -p /root/openshift-upi/openshift-images/
11. mkdir -p /root/openshift-upi/files-openshift-install/
12. mkdir -p /root/openshift-upi/setupdir-openshift-install/

RHOCP Hosts
Distributed Hosts that set up and run CP4S. For now, we are installing RHOC on them.
- Boot Node
  1. In vSphere Client, under VMs and Templates, select your Bootstrap server
  2. Select Actions > Edit Settings
  3. Go to the tab VM Options
  4. Expand Boot Options
  5. Select Force BIOS setup
  6. Click OK
  7. Start the VM with the green arrow or Actions > Power > Power On
  8. In the boot tab, move Network boot to first instance
  9. Select Save and Exit
  10. After PXE boot loads the menu, select Bootstrap
    Note: The bootstrap updates itself to the latest. Despite the version provided, by default RHCOS updates itself.
    Some errors are expected due to components not being loaded.
    The VM reboots two or more times. Allow at least 20 minutes for this process.
  11. After restart is complete, bootstrap will show the login prompt.
  12. From the services host:
    ssh core@{bootstrap_FQDN}} "journalctl -b -f -u release-image.service -u bootkube.service"
    NOTE: core is default user for RHOC.
  13. Wait for logs to display four or more created yaml files:
    99_openshift-cluster-api_master-user-data-secret.yaml
    99_openshift-cluster-api_worker-user-data-secret.yaml
    99_openshift-machineconfig_99-master-ssh.yaml
    99_openshift-machineconfig_99-worker-ssh.yaml
  14. ssh core@{bootstrap_FQDN}} "openshift-install wait-for bootstrap-complete --log-level=debug"
  15. Wait for "INFO API v{version} up" to display
- Control Node
  1. In vSphere Client, under VMs and Templates, select your Control server
  2. Select Actions > Edit Settings
  3. Go to the tab VM Options
  4. Expand Boot Options
  5. Select Force BIOS setup
  6. Click OK
  7. Start the VM with the green arrow or Actions > Power > Power On
  8. In the boot tab, move Network boot to first instance
  9. Select Save and Exit
  10. After PXE boot loads the menu, select master
    Note: The bootstrap updates itself to the latest. Despite the version provided, by default RHCOS updates itself.
    Some errors are expected due to components not being loaded.
    The VM reboots two or more times. Allow at least 20 minutes.
  11. Wait for login prompt to display
  12. ssh core@{controller_FQDN}} "openshift-install wait-for bootstrap-complete --log-level=debug"
  13. Wait for "Bootstrap status: Complete"
  14. Repeat steps 1 - 13 for each Control Node in your environment
  15. Verify that all master nodes are in Ready state:
    oc login -u kubeadmin -p $(cat /root/openshift-upi/setupdir-openshift-install/auth/kubeadmin-password) https://console-openshift-console.apps.ejc-cp4s.oc.intranet:6443 --insecure-skip-tls-verify=true
    NOTE: The credentials for the default user, kubeadmin, and the password are stored in /root/openshift-upi/setupdir-openshift-install/auth/
  16. Verify all Cluster Operators:
    oc get clusteroperators AVAILABLE = True PROGRESSING = False DEGRADED = False
    NOTE: The pods for each Cluster Operator (co) can take few minutes to transition to the right state.
  17. oc whoami --show-console
  18. Save URL in notes
- Compute Node
  WARNING: DO NOT INSTALL WORKER NODES IN PARALLEL!
  1. In vSphere Client, under VMs and Templates, select your Compute server
  2. Select Actions > Edit Settings
  3. Go to the tab VM Options
  4. Expand Boot Options
  5. Select Force BIOS setup
  6. Click OK
  7. Start the VM with the green arrow or Actions > Power > Power On
  8. In the boot tab, move Network boot to first instance
  9. Select Save and Exit
  10. After PXE boot loads the menu, select worker
    Note: The bootstrap updates itself to the latest. Despite the version provided, by default RHCOS updates itself.
    Some errors are expected due to components not being loaded.
    The VM reboots two or more times. Allow at least 20 minutes.
  11. Once you see the login prompt, repeat steps 1 - 10 for each Compute Node
  12. Wait for all Compute Nodes to be in "Ready" state:
    oc get nodes If you don't see them or they are in "NotReady" state, wait 2 minutes and poll again: oc get csr oc get csr -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' | xargs --no-run-if-empty oc adm certificate approve oc get nodes
