Description Wenjing Zheng 2021-06-29 05:50:35 UTC 
This bug was initially created as a copy of Bug #1952610

I am copying this bug because: 



Description of problem:
When the cluster is installed in a new region that is unknown in the AWS SDK version being used, the image-registry pod crashes.


How reproducible:
100%


Steps to Reproduce:
1. Install a cluster in ap-northeast-3. Use custom endpoints for ec2 and elb so that the machine-api-operator can create the worker machines.
2. Note that the image-registry pods crashloop.

Actual results:

Expected results:
The image-registry will accept the new region as it matches the regular expression for a region in the default AWS partition.
