Chapter 4. Installing a cluster 4.1. Cleaning up installations In case of an earlier failed deployment, remove the artifacts from the failed attempt before trying to deploy OpenShift Container Platform again. Procedure Power off all bare-metal nodes before installing the OpenShift Container Platform cluster by using the following command: USD ipmitool -I lanplus -U <user> -P <password> -H <management_server_ip> power off Remove all old bootstrap resources if any remain from an earlier deployment attempt by using the following script: for i in USD(sudo virsh list | tail -n +3 | grep bootstrap | awk {'print USD2'}); do sudo virsh destroy USDi; sudo virsh undefine USDi; sudo virsh vol-delete USDi --pool USDi; sudo virsh vol-delete USDi.ign --pool USDi; sudo virsh pool-destroy USDi; sudo virsh pool-undefine USDi; done Delete the artifacts that the earlier installation generated by using the following command: USD cd ; /bin/rm -rf auth/ bootstrap.ign master.ign worker.ign metadata.json \ .openshift_install.log .openshift_install_state.json Re-create the OpenShift Container Platform manifests by using the following command: USD ./openshift-baremetal-install --dir ~/clusterconfigs create manifests 4.2. Deploying the cluster via the OpenShift Container Platform installer Run the OpenShift Container Platform installer: USD ./openshift-baremetal-install --dir ~/clusterconfigs --log-level debug create cluster 4.3. Following the progress of the installation During the deployment process, you can check the installation's overall status by issuing the tail command to the .openshift_install.log log file in the install directory folder: USD tail -f /path/to/install-dir/.openshift_install.log 4.4. Verifying static IP address configuration If the DHCP reservation for a cluster node specifies an infinite lease, after the installer successfully provisions the node, the dispatcher script checks the node's network configuration. If the script determines that the network configuration contains an infinite DHCP lease, it creates a new connection using the IP address of the DHCP lease as a static IP address. Note The dispatcher script might run on successfully provisioned nodes while the provisioning of other nodes in the cluster is ongoing. Verify the network configuration is working properly. Procedure Check the network interface configuration on the node. Turn off the DHCP server and reboot the OpenShift Container Platform node and ensure that the network configuration works properly. 4.5.
