What happened?

When trying to configure authentication, it seems that the documentation is misleading:

It says:

Use DOCKER_CONFIG_FILE environment variable.
export DOCKER_CONFIG_FILE=/some/location/config.json
Use dockerConfigFile java property
java -DdockerConfigFile=/some/location/config.json

here: https://java.testcontainers.org/modules/docker_compose/#using-private-repositories-in-docker-compose

But: dockerConfigFile is not used.
and it looks like you should not use DOCKER_CONFIG_FILE, but DOCKER_AUTH_CONFIG instead.

Not having the ability to use a system property is annoyng, since it makes it diffucult to configure docker authentication with java code directly.

That's what I infer from: https://github.com/testcontainers/testcontainers-java/blob/main/core/src/main/java/org/testcontainers/utility/RegistryAuthLocator.java and from my tests.

Relevant log output

Beginne mit core/src/main/java/org/testcontainers/utility/RegistryAuthLocator.java und vergleiche die Verarbeitung der Konfiguration dort mit der Docker-Compose-Dokumentation auf der referenzierten Seite. Ermittle, warum dockerConfigFile nicht verwendet wird, und überprüfe anschließend, ob die dokumentierten Konfigurationsoptionen, einschließlich der Konfiguration über Java-Systemeigenschaften, für die Docker-Authentifizierung konsistent funktionieren.
