Hi all, I'm using pants 2.17 with

docker_environment()

to run a test in a container and pants fails to pull the image from a private registry. The image is available in a private JFrog Artifactory, with credentials set up in my

~/.docker/config.json

so that

docker pull

works. I don't have the pants docker backend enabled (since I don't intend to build an image via pants).

pants.toml

only contains one entry under

environments-preview.names

for connecting the test to the

docker_environment()

, which looks like this:

docker_environment(
    name="image_test_video_utils",
    image="<http://artifactory.mycorp.com/test_video_utils:0.1|artifactory.mycorp.com/test_video_utils:0.1>",
)

When the image is not yet available on the host (i.e. not listed by

docker image ls

) and I run

pants test ..

, pants fails to pull the image:

[INFO] Starting: Pulling Docker image `<http://artifactory.mycorp.com/test_video_utils:0.1|artifactory.mycorp.com/test_video_utils:0.1>` because the image is missing locally.
[INFO] Completed: Pulling Docker image `<http://artifactory.mycorp.com/test_video_utils:0.1|artifactory.mycorp.com/test_video_utils:0.1>` because the image is missing locally.
[ERROR] 1 Exception encountered:

IntrinsicError: Failed to pull image `<http://artifactory.mycorp.com/test_video_utils:0.1|artifactory.mycorp.com/test_video_utils:0.1>`: Failed to pull Docker image `<http://artifactory.mycorp.com/test_video_utils:0.1|artifactory.mycorp.com/test_video_utils:0.1>`: DockerResponseServerError { status_code: 500, message: "Head \"<https://artifactory.mycorp.com/v2/docker-local/test_video_utils/manifests/0.1>\": unknown: Authentication is required" }

However, when I pull the image manually via

docker pull

, there's no such error and it works as expected. Any idea how to fix that? Thank you!
