What happened?

Getting the following error when trying to run local test cases in Ubuntu. This is the same issue reported with Podman here.

com.example.db-utils-testExecution error (InternalServerErrorException) at org.testcontainers.shaded.com.github.dockerjava.core.DefaultInvocationBuilder/execute (DefaultInvocationBuilder.java:247).
Status 500: {"message":"failed to Lchown \"/etc/mysql/conf.d\" for UID 1467898976, GID 1467800513: lchown /etc/mysql/conf.d: invalid argument"}

This issue is happening for us with Ubuntu 22.04 with Clojure and kaocha where we are using testcontainer for running tests locally that spins up MySQL. It however works with Gitlab pipeline. This is really blocker for us. The same setup works on a mac.

I have tried overriding the MySQLContainer from Clojure side using proxy as mentioned in the linked bug, but it is not working. I don't get any error at this time, but the tests get stuck. I am also not able trace any logs because I couldn't find a way to enable printing logs in kaocha.

Kindly requesting your input on how to solve this. Thanks.

Research direction

Reproduce the failure with Ubuntu 22.04, Docker 27.0.3, and the MySQL module at version 1.19.8, then inspect MySQLContainer behavior around /etc/mysql/conf.d. Compare the linked Podman issue and verify that the rootless setup runs the local tests without the lchown error or a hang.
