Agent-based Installer for OpenShift Container Platform
Learn about using Red Hat's Agent-based Installer to provision OpenShift Container Platform on OCI.
The Agent-based Installer is provided for advanced users who need customized infrastructure configurations, and for users working in disconnected environments. Installing a cluster using this method requires prior knowledge OCI infrastructure services including Networking, Load Balancer, DNS, Compute, Object Storage, IAM and Tagging. Expect the agent-based installer to take more time than the Assisted Installer.
Provisioning Resources for the Agent-based Installer
For the OCI resources required by the OpenShift cluster (for example, the Compute instances, VCN, load balancers, and other infrastructure), you can provision these resources with an OCI-provided Terraform script, using the OCI Resource Manager service, or you provision the resources manually. If you're in a disconnected environment, or you need to configure a firewall or do other advanced configuration, you must provision resources manually.
Option 1: Using Terraform to Provision Resources
OCI provides a Terraform script for provisioning new compute nodes, which you download from the page in GitHub. The script is in the Assets section of the release, in a .zip folder named create-cluster-v1.x.x.zip, where "1.x.x" refers to the version number. For example, version 1.0.0 of the script is in a zip folder named create-cluster-v1.0.0.zip
Option 2: Provisioning Resources Manually
See Provisioning OCI Resources for the Agent-based Installer in Disconnected Environments for details on the resources you need to provision if you are not using the Terraform script.
Getting Started
Start by reading Installing a cluster on Oracle Cloud Infrastructure (OCI) by using the Agent-based Installer in the Red Hat documentation.
To begin provisioning resources, use the instructions for either Terraform provisioning or manual provisioning, depending on your use case:
- Terraform provisioning: See Provisioning Cluster Infrastructure Using Terraform
- Manual provisioning: See Provisioning OCI Resources for the Agent-based Installer in Disconnected Environments
