TESTCONTAINERS_HUB_IMAGE_NAME_PREFIX should first try to pull images using docker rather than https

[ashmeet-kandhari]

Expected Behaviour
Whenever testcontainers try to pull images it should pull using docker pull <image> rather than using http(s).
Because incase of private repositories like AWS ECR access is configured via IAM roles and for http request it requires explicit setting of creds

Actual Behaviour
Testcontainers use https to pull the images

Testcontainer Logs
console.log

Error:     2025-04-17T10:25:57.625Z testcontainers [ERROR] Failed to pull image "<AWS_ACCOUNT_ID>.dkr.ecr.eu-west-1.amazonaws.com/testcontainers/docker.io/testcontainers/ryuk:0.11.0": Error: (HTTP code 500) server error - Head "https://<AWS_ACCOUNT_ID>.dkr.ecr.eu-west-1.amazonaws.com/v2/testcontainers/docker.io/testcontainers/ryuk/manifests/0.11.0": no basic auth credentials

Steps to Reproduce

1. Run it in a server where AWS private repository is set via TESTCONTAINERS_HUB_IMAGE_NAME_PREFIX
2. Try to run the testcontainers test

Environment Information

• Operating System: ubuntu
• Docker Compose Version: 2.32.4

@ashmeet-kandhari This shouldn't be an issue. The reason you're able to pull an image using docker pull is because there'll be a credential provider set up which has been configured for your AWS account. You should be able to see this in your ~/.docker/config.json. Testcontainers uses this same mechanism to authenticate with container registries.

If there is an issue could you please share (with details redacted) your ~/.docker/config.json file, or provide more info regarding why your docker pull works.
