OC Cluster creating on on AWS

[Anantha J]

Pls direct if the similar issue was reported earlier.

While creating OC  cluster on AWS domain, getting the following (US EAST is default)

Any idea how to clean required in AWS

Anantha,

Yes this issue has been covered extensively in previous threads. If you're deploying to us-east-1 (which has 6 AZ's) it will attempt to create 1 Elastic IP address per AZ. The EIP limit in AWS is 5, and to go beyond that limit you have to fill out a form and submit it for approval.

The workaround for this is to use a region which has fewer AZs, such as us-east-2 (which has only has 3, meaning the installer will only create 3 EIPs which is under the AWS limit of 5).

Hope this helps,

-Josh

Since 0.16.1 you can reduce installer-created subnets by explicitly
setting zones in your install-config.yaml [1,2], so using us-east-1
without bumping limits is possible.

Cheers,
Trevor

Hello Josh,

Thanks a lot. I opted on London and worked perfect !!! Hope fully can replicate all the use cases of OS on AWS without incrementing further capacity. Truly an example of Cloud Interoperability

Cheers
