Need advice how to make Spinnaker work with aws ecr?
Got the answer from an official Spinnaker slack channel. That adding an iam policy to the clouddriver pod won't work unfortunately since it uses the docker client instead of the aws client. The workaround to make it work can be found here
Note* Ecr support currently is broken in halyard.This might get fixed in future after halyard migrates from the kubernetes v1 -> v2 or earlier so please verify with community or docs.
