Background Info

With the implementation of OCM-1227, there is now a list of valid subnet IDs that the user can choose from for their VPC.

Today the user is expected to type these subnets into a free entry field, which isn't validated until the ROSA cluster is attempted to be created and if invalid, is surfaced as the preflight error PreflightMachineCIDRContainsSubnetCIDR, which is one of the top 5 most commonly occurring preflight ROSA errors.

This design will force the user to choose a valid subnet ID and thus reduce or remove the occurrence of that error from the UI, while OCM-1227 reduces or removes it from the CLI.

Goals

• Create mockup of the ROSA wizard networking step for VPC settings, where the user specifies subnet(s), and include the ability to pick from a list

Definition of Done - targeted for 237/238

• Create design deliverable(s) capturing Goal deliverables
• Link design in this story
• Review with all relevant stakeholders including Abhishek, Will, and UI engineering
