We are seeing test flakes with the error message mysql.Endpoint() = port not found. The code we use to create the container is attached below. In particular, we use both wait.ForListeningPort("3306/tcp") and wait.ForLog("port: 3306") to make sure we wait until the container is running and available. However, it seems even with that, GenericContainer will occasionally return without being ready, as evidenced by the fact that Endpoint returns an error about the port not being found.
