chenyulin0719 opened a new issue, #4455:
URL: https://github.com/apache/gravitino/issues/4455
### Version
main branch
### Describe what's wrong
In the gravitino-playground, the catalog backend is MySQL. However, the
docker-compose file does not specify the dependency between MySQL and
Gravitino, which leads to the following issues:
1. Gravitino cannot be started using `./launch-playground.sh gravitino` (the
container is up, but Gravitino process is down)
2. When running `./launch-playground.sh`, there is no guarantee that MySQL
will start before Gravitino.
### Error message and/or stacktrace
In `/root/gravitino/logs/gravitino-server.out` after run
`./launch-playground.sh gravitino`
```

### How to reproduce
Run `./launch-playground.sh gravitino` in gravitino-playground main branch.
### Additional context
I will create a PR to fix the docker-compose file in gravitino-playground.
(Please let me know if I should create this issue in gravitino-playground
repository)
