USER STORY:

• As an developer, I would like to deploy ultra-low-latency sensitive applications in Wavelength Zones without needing an external load balancer to ingress traffic to edge nodes, so I can expand my application coverage using OCP
• As an OCP administrator, I would like to create machine sets to deploy instances in Wavelength Zones in public subnets using, so I can quickly develier nodes to developers deploy applications to that zones
• As an OCP developer, I would like to support MAPI to assign carrier public IP address when launching nodes in subnets in Wavelength Zones, so administrators can use the same interface as regular zone to extend worker nodes to edge zones.

Goal:

Wavelength Zones operates in Carrier Network, to ingress traffic to instances running into that zones, the Carrier IP Address must be assigned. The Carrier IP address is assigned to the instance when the network interface flag AssociateCarrierIpAddress must be set to when provisioning the instance.

The PublicIP is the existing flag available in the MachineSet to assign public IP address to node running in regular zone, the goal of this card is to teach MAPI AWS provider to look at the zone type for the subnet, and when the value is 'wavelength-zone' the flag AssociateCarrierIpAddress must be set to true, instead of the default AssociatePublicIpAddress, allowing EC2 service to assign public IP address in the carrier network.

Required:

• MAPI AWS provider must support public IP assignment by discovering the zone type without changing the API
•  

ACCEPTANCE CRITERIA:

• MAPI AWS Provider PR must be created
• PR must be passing unit tests
• PR must be approved
