✨ New Features

Trunk Sub-Port Creation

• Sub-ports can be added to trunk ports for OpenStack Machines

📋 Technical Details

API Changes

• Added SubportOpts and ResolvedSubportSpec types to API
• Since sub-ports and ports are essentially the same entities
  CommonPortOpts and CommonResolvedPortSpec types were introduced as a
  basis for regular ports and trunk subports
• Added SubPortStatus to keep track of ports which are associated with
  trunk

Compatibility

• Base: Kubernetes Cluster API v1.8+
• OpenStack: Pike+ (same as upstream)
• Kubernetes: v1.28+ (tested with v1.33)

🚀 Container Images

docker pull ghcr.io/mirantis/cluster-api-provider-openstack:v0.12.5-mirantis.1

Supported platforms:

• linux/amd64
• linux/arm
• linux/arm64
• linux/ppc64le
• linux/s390x

🔄 Upgrade Notes

This release is based on the stable v0.12.4 upstream version and can be used as a drop-in replacement. The new properties for ports in OpenStackMachine and OpenStackMachineDeployment just set to nil value on migration and do not affect existing entitites

🤝 Contributing

This release represents Mirantis's enterprise hardening of the upstream project while maintaining full compatibility. Features developed here are also contributed back to the upstream project.
