The MariaDB container fails to start with 'Bad magic header in tc log' error
when the data directory has incorrect permissions or was previously corrupted.
This occurs during first-time setup of the AVideo lab environment.
The fix:
- Creates a custom entrypoint script that detects and removes corrupted tc.log
files by checking the magic header (should be 01 00 00 00)
- Modifies Dockerfile.mariadb to integrate the fix script into the original
MariaDB entrypoint using sed
- Ensures the fix runs automatically before MariaDB initialization
This allows the lab to start successfully on first run without manual intervention.
