Chapter 1. Preparing to install on {ibmpowerProductName} Virtual Server The installation workflows documented in this section are for IBM Power Virtual Server infrastructure environments. 1.1. Prerequisites You reviewed details about the OpenShift Container Platform installation and update processes. You read the documentation on selecting a cluster installation method and preparing it for users . Important IBM Power Virtual Server using installer-provisioned infrastructure is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope . 1.2. Requirements for installing OpenShift Container Platform on IBM Power Virtual Server Before installing OpenShift Container Platform on IBM Power Virtual Server, you must create a service account and configure an IBM Cloud account. See Configuring an IBM Cloud account for details about creating an account, configuring DNS and supported IBM Power Virtual Server regions. You must manually manage your cloud credentials when installing a cluster to IBM Power Virtual Server. Do this by configuring the Cloud Credential Operator (CCO) for manual mode before you install the cluster. 1.3. Choosing a method to install OpenShift Container Platform on IBM Power Virtual Server You can install OpenShift Container Platform on IBM Power Virtual Server using installer-provisioned infrastructure. This process involves using an installation program to provision the underlying infrastructure for your cluster. Installing OpenShift Container Platform on IBM Power Virtual Server using user-provisioned infrastructure is not supported at this time. See Installation process for more information about installer-provisioned installation processes. 1.3.1. Installing a cluster on installer-provisioned infrastructure You can install a cluster on IBM Power Virtual Server infrastructure that is provisioned by the OpenShift Container Platform installation program by using one of the following methods: Installing a customized cluster on IBM Power Virtual Server : You can install a customized cluster on IBM Power Virtual Server infrastructure that the installation program provisions. The installation program allows for some customization to be applied at the installation stage. Many other customization options are available post-installation . Installing a cluster on IBM Power Virtual Server into an existing VPC : You can install OpenShift Container Platform on IBM Power Virtual Server into an existing Virtual Private Cloud (VPC). You can use this installation method if you have constraints set by the guidelines of your company, such as limits when creating new accounts or infrastructure. Installing a private cluster on IBM Power Virtual Server : You can install a private cluster on IBM Power Virtual Server. You can use this method to deploy OpenShift Container Platform on an internal network that is not visible to the internet. Installing a cluster on IBM Power Virtual Server in a restricted network : You can install OpenShift Container Platform on IBM Power Virtual Server on installer-provisioned infrastructure by using an internal mirror of the installation release content. You can use this method to install a cluster that does not require an active internet connection to obtain the software components. 1.4. Configuring the Cloud Credential Operator utility The Cloud Credential Operator (CCO) manages cloud provider credentials as Kubernetes custom resource definitions (CRDs). To install a cluster on IBM Power Virtual Server, you must set the CCO to manual mode as part of the installation process. To create and manage cloud credentials from outside of the cluster when the Cloud Credential Operator (CCO) is operating in manual mode, extract and prepare the CCO utility ( ccoctl ) binary. Note The ccoctl utility is a Linux binary that must run in a Linux environment. Prerequisites You have access to an OpenShift Container Platform account with cluster administrator access. You have installed the OpenShift CLI ( oc ). Procedure Obtain the OpenShift Container Platform release image by running the following command: USD RELEASE_IMAGE=USD(./openshift-install version | awk '/release image/ {print USD3}') Obtain the CCO container image from the OpenShift Container Platform release image by running the following command: USD CCO_IMAGE=USD(oc adm release info --image-for='cloud-credential-operator' USDRELEASE_IMAGE -a ~/.pull-secret) Note Ensure that the architecture of the USDRELEASE_IMAGE matches the architecture of the environment in which you will use the ccoctl tool. Extract the ccoctl binary from the CCO container image within the OpenShift Container Platform release image by running the following command: USD oc image extract USDCCO_IMAGE --file="/usr/bin/ccoctl" -a ~/.pull-secret Change the permissions to make ccoctl executable by running the following command: USD chmod 775 ccoctl Verification To verify that ccoctl is ready to use, display the help file. Use a relative file name when you run the command, for example: USD ./ccoctl.rhel9 Example output OpenShift credentials provisioning tool Usage: ccoctl [command] Available Commands: alibabacloud Manage credentials objects for alibaba cloud aws Manage credentials objects for AWS cloud gcp Manage credentials objects for Google cloud help Help about any command ibmcloud Manage credentials objects for IBM Cloud nutanix Manage credentials objects for Nutanix Flags: -h, --help help for ccoctl Use "ccoctl [command] --help" for more information about a command.
