Docker Compose dev service follow-container-logs logs almost everything to error

[LarsSven]

Describe the bug

When using the quarkus.compose.devservices.follow-container-logs=true property with docker compose dev services, certain services are almost entirely printed to log-level ERROR in Quarkus, which is especially an issue in test mode because ERROR messages are printed twice due to stderr + log ERROR, so it's making the logs extremely verbose.

Quarkus produces a lot of logs like for example:

2025-11-26 15:08:58,919 ERROR [io.qua.dev.dep.com.ComposeProject] (docker-java-stream-287857620) [kubernetes-1] : time="2025-11-26T14:08:58Z" level=info msg="Datastore connection validated successfully, proceeding with bootstrap data generation"

Where the log is printed within the container as info, but is printed as ERROR by Quarkus

Expected behavior

Quarkus would not print info logs of followed containers into its own ERROR log level

Actual behavior

Quarkus prints info logs into the ERROR log level

How to Reproduce?

1. Clone https://gitlab.com/l.s.andringa1/quarkus-compose-reproducer.git
2. Run ./gradlew test or ./gradlew quarkusDev (test shows the duplicated logs the best)
3. Observe that everything from the kubernetes service is printed on ERROR

Output of uname -a or ver

Ubuntu 25.10

Output of java -version

Quarkus version or git rev

3.29.4

Build tool (ie. output of mvnw --version or gradlew --version)

@geoand would it be possible to have a look into this? This makes it very hard to not be overwhelmed by a ton of logs when trying to use the compose dev service.

I tried this, but I think there is something wrong with my Docker setup, because I got the following:

Yeah I don't know what that is, never seen that before

Right, first time I've seen as well...
