Feature Overview (aka. Goal Summary)
Add OpenStackLoadBalancerParameters and add an option for setting the load-balancer IP address for only those platforms where it can be implemented.
Goals (aka. expected user outcomes)
As a user of on-prem OpenShift, I need to manage DNS for my OpenShift cluster manually. I can already specify an IP address for the API server, but I cannot do this for Ingress. This means that I have to:
- Manually create the API endpoint IP
- Add DNS for the API endpoint
- Create the cluster
- Discover the created Ingress endpoint
- Add DNS for the Ingress endpoint
I would like to simplify this workflow to:
- Manually create the API and Ingress endpoint IPs
- Add DNS for the API and Ingress endpoints
- Create the cluster
Requirements (aka. Acceptance Criteria):
Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed. Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.
| Deployment considerations | List applicable specific needs (N/A = not applicable) |
| Self-managed, managed, or both | |
| Classic (standalone cluster) | |
| Hosted control planes | |
| Multi node, Compact (three node), or Single node (SNO), or all | |
| Connected / Restricted Network | |
| Architectures, e.g. x86_x64, ARM (aarch64), IBM Power (ppc64le), and IBM Z (s390x) | |
| Operator compatibility | |
| Backport needed (list applicable versions) | |
| UI need (e.g. OpenShift Console, dynamic plugin, OCM) | |
| Other (please specify) |
Questions to Answer (Optional):
Out of Scope
- Although the Service API's loadBalancerIP API field was defined to be platform-agnostic, it wasn't consistently supported across platforms, and Kubernetes 1.24 has even deprecated it for this reason: https://github.com/kubernetes/kubernetes/pull/107235. We would not want to add a generic option to set loadBalancerIP given that it is deprecated and that it would work only on some platforms and not on others.
Background
- This request is similar to RFE-843 (for AWS), RFE-2238 (for GCP), RFE-2824 (for AWS and MetalLB, and maybe others), RFE-2884 (for AWS, Azure, and GCP), and RFE-3498 (for AWS). However, it might make sense to keep this RFE specifically for OpenStack.
