TeamCity: push docker image to AWS ECR

Question

Running TeamCity 2019.1.4 with one server and three separate agents. Both agents and the server are running in their respective server/agent containers in separate EC2 instances. I want the build artifact (docker image) to be pushed to the ECR. Permission is configured via IAM role. I am getting Unauthorized error when pushing/pulling. Manually pulling image from the agent EC2 host works. But manually pulling from within the agent EC2 container gives the same error. How do I configure the TeamCity agent container to identify itself as the host machine?

PS: An option I am trying to avoid is to run TeamCity agents in a classic mode (manual installation) which will most likely work.

did you tired to login first before pull or push image? `$(aws ecr get-login --no-include-email --region us-west-2)` — Adiii, Oct 16 '19 at 11:07
you can find a solution in this [document](https://ngeor.com/2017/12/30/using-aws-ecr-as-a-docker-registry.html) about `teamcity` push to ecr repository. — GNOKOHEAT, Oct 16 '19 at 11:35

Do the following:

in TeamCity project configuration, add ECR connection.
then, in the build configuration, add build feature, add "Docker Support".
make sure the choice "Log in to the Docker registry before the build" is checked and you choose the ECR connection from the project configuration.

But your not in luck if you want to log into several registries simultaneously. This does not seem to be supported. – Paul Michalik Apr 11 '20 at 11:59
Well, it does actually work with the latest TeamCity. I have got multiple ECR connections on a build config. – naimdjon Jun 25 '20 at 09:42
Interesting... I'll give it a try. For now I log into different registries manually. – Paul Michalik Jun 26 '20 at 10:37
