[Bug]: Fully qualified image names are considered "incompatible"

Module

PostgreSQL

Testcontainers version

1.17.6

Using the latest Testcontainers version?

Yes

Host OS

n/a

Host Arch

n/a

Docker version

n/a

What happened?

Trying to use fully qualified names makes Testcontainers think it's an incompatible image

Relevant log output

IllegalStateException: Failed to verify that image 'docker.io/postgres:16-alpine' is a compatible substitute for 'postgres'.



IllegalStateException: Failed to verify that image 'docker.io/library/postgres:16-alpine' is a compatible substitute for 'postgres'.



IllegalStateException: Failed to verify that image 'library/postgres:16-alpine' is a compatible substitute for 'postgres'.

Additional Information

Testcontainers should be using docker.io/library/postgres as the actual expected image name.

Shorthand image names should be handled by adding the default docker.io/library/ prefix

library/postgres is a valid image. Take into account version 1.17.6 is an old version.

Just encountered this issue. As a Podman user, I use the full image name (docker.io/postgres:18-alpine) which is considered incompatible. Testcontainers should ignore the docker.io part
