The installation workflows documented in this section are for IBM Cloud VPC infrastructure environments. IBM Cloud Classic is not supported at this time. For more information about the difference between Classic and VPC infrastructures, see the IBM documentation.
Prerequisites
You reviewed details about the OKD installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.
Requirements for installing OKD on IBM Cloud VPC
Before installing OKD 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.
Choosing a method to install OKD on IBM Cloud VPC
You can install OKD on IBM Cloud VPC using installer-provisioned infrastructure. This process involves using an installation program to provision the underlying infrastructure for your cluster. Installing OKD 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.
Installing a cluster on installer-provisioned infrastructure
You can install a cluster on IBM Cloud VPC infrastructure that is provisioned by the OKD 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 OKD network configuration during installation, so that your cluster can coexist with your existing IP address allocations and adhere to your network requirements.
Installing a cluster on IBM Cloud VPC into an existing VPC: You can install OKD on an existing IBM 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 an existing VPC: You can install a private cluster on an existing Virtual Private Cloud (VPC). You can use this method to deploy OKD on an internal network that is not visible to the internet.
