Issue connecting to ECR using Spinnaker on Kubernetes
Update for anyone else who runs into this issue, when Spinnaker is installed using helm it's using an older version of the Halyard container which doesn't have the AWS CLI tool. This seems to be hard to resolve as just updating the values file for helm to the latest version doesn't seem to work and I didn't dig much into the specifics as didn't want to go down that rabbit hole.
