IBM Cloud 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 https://access.redhat.com/support/offerings/techpreview/.
Before installing OpenShift Container Platform on IBM Cloud VPC, you must create a service account and configure an IBM Cloud account. See Configuring an IBM Cloud account for details about creating an account, enabling API services, configuring DNS, IBM Cloud account limits, and supported IBM Cloud VPC regions.
You must manually manage your cloud credentials when installing a cluster to IBM Cloud VPC. Do this by configuring the Cloud Credential Operator (CCO) for manual mode before you install the cluster. For more information, see Configuring IAM for IBM Cloud VPC.
You can install OpenShift Container Platform on IBM Cloud VPC 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 Cloud VPC using user-provisioned infrastructure is not supported at this time.
See Installation process for more information about installer-provisioned installation processes.
You can install a cluster on IBM Cloud VPC infrastructure that is provisioned by the OpenShift Container Platform installation program by using one of the following methods:
Installing a customized cluster on IBM Cloud VPC: You can install a customized cluster on IBM Cloud VPC 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 Cloud VPC with network customizations: You can customize your OpenShift Container Platform network configuration during installation, so that your cluster can coexist with your existing IP address allocations and adhere to your network requirements.
