## Tips & Tricks
- If logs show permission errors, it may be required that the local folders need write permissions.
the easiest thing to do is to run the following, in the same directory as the `docker-compose.yml` file:
```sh
chmod -R 777 ./config ./data ./logs ./plugins ./client-plugins ./bleve
```
