OpenShift OPCT - Sprint 253
Description
Epic Goal
- Implement support in openshift-install to install OpenShift clusters using CAPI with user-provided Public IPv4 Pool ID and create resources* which consumes Public IP when publish strategy is "External".
*Resources which consumes public IPv4: bootstrap, API Public NLB, Nat Gateways
Why is this important?
- The default OpenShift installation on AWS uses multiple IPv4 public IPs which Amazon will start charging for starting in February 2024.
Scenarios
- As a customer with BYO Public IPv4 pools in AWS, I would like to install OpenShift cluster on AWS consuming public IPs for my own CIDR blocks, so I can have control of IPs used by my the services provided by me and will not be impacted by AWS Public IPv4 charges
Acceptance Criteria
- CI - MUST be running successfully with tests automated
- Release Technical Enablement - Provide necessary release enablement details and documents.
- ...
Dependencies (internal and external)
- ...
Previous Work (Optional):
- …
Open questions::
- Is there a method to use the pool by default for all Public IPv4 claims from a given VPC/workload? So the implementation doesn't need to create EIP and associations for each resource and subnet/zone.
