Provide credentials for base image different from the image to be built

[chbiel]

Hi,
i have the following setup:

Dockerfile of "child" image

FROM quay.io/team/base
...do something...

quay.io need authentication and the following would work as expected.

- name: docker-image-tools
    type: docker-image
    icon: docker
    source:
      repository: quay.io/team/base
      username: ((quay_username))
      password: ((quay_password))

Now I want to build the "child" image above, but push it to AWS ECR:

- name: docker-image-child
    type: docker-image
    icon: docker
    source:
      repository: account.dkr.ecr.region.amazonaws.com/child

When I execute that I get an error that authentication for quay.io is missing (what is basically OK).

But now the question:
Can I provide different credentials for the base image and the image to created/push? Or do i have to ensure that the base image and the target image are in the same repo?
I did not find anything related in the docs

Thanks in advance!

I have the same issue and I am wondering why this issue does not affect many more people?

Would it somehow be possible to provide the content of the '.docker/config.json' file to the resource? This way one could craft such a config.json file that contains all needed credentials.

This makes this resource completely unusable when pushing to a different repository now that dockerhub pretty much requires authentication due to rate limiting as you can't authenticate to dockerhub to build the image and push to any different repository
