What happened?

Trying to use docker images from an internal proxy e.g.

export TESTCONTAINERS_COMPOSE_CONTAINER_IMAGE=xxx.yy.zz.com/dockerhub/library/docker:24.0.3

(Notice I set the image value to end in 3)

but when I run the integration tests via Gradle it doesn't get picked up

I also tried creating a testcontainers.properties in the classpath (and recompile) and a .testcontainers.properties in my $HOME but I still see the same behavior

NOTE: Using ComposeContainer and not DockerComposeContainer as the latter is deprecated.

Relevant log output

Looks to be similar (different symptom but same underlying issue?) as https://github.com/testcontainers/testcontainers-java/issues/9222
