v1.0.0 release preview

[dfoster-oracle]

What's Changed

• Upgraded OCI CCM and CSI driver versions to v1.30
  • Adds support for using Bare Metal instances as OpenShift cluster nodes
  • Adds support for provisioning Raw Block Volumes (no filesystem)
• Major Terraform refactor
  • Instead of one infrastructure.tf file that can only create a cluster, we now have the terraform-stacks directory which contains individual Terraform stacks, each with a specific purpose:
    • add-nodes
    • create-cluster
    • create-tags
  • Use shared_modules across all Terraform stacks
  • Packaging of stacks into versioned and distributable zip files
• Terraform improvements
  • Instances are now distributed across Availability and Fault Domains if available
  • create-cluster stack can be used for a connected Agent-based installation
  • Stacks now output a dynamic_custom_manifest which contains all custom manifests necessary for OpenShift installation, pre-formatted with OCI CCM and CSI secrets, and condensed into a single manifest for easy uploading/pasting
• New custom manifests
  • All necessary custom manifests are now formatted and output by the Terraform stacks
  • oci-eval-user-data.yml executes scipts uploaded during instance creation
    • iscsi-oci-configure-secondary-nic.sh evaluates and configures the instance network settings for iSCSI boot volumes (Bare Metal)
  • cluster-network.yml modifies the default cluster Network subnet to avoid conflicts with iSCSI boot volumes in OCP 4.17+
• Versioned OCI CCM and CSI manifests
  • Allows for upgrading of CCM and CSI drivers on an existing cluster

@dfoster-oracle I see a mention of create-cluster stack can be used for a connected Agent-based installation

Will the disconnected Agent-based installation be covered in a seperate PR?

We haven't yet done enough modifications to create-cluster to work with disconnected agent based, but it's on the list.
