A bouncer key can be any string but we recommend an alphanumeric value for consistency with the crowdsec-generated keys and to avoid problems with escaping special characters.

## Environment Variables
Note for persistent configurations (i.e. bind mount or volumes): when a
variable is set, its value may be written to the appropriate file (usually
config.yaml) each time the container is run.

| __LAPI__ | | (useless with DISABLE_LOCAL_API) |
| `USE_WAL` | false | Enable Write-Ahead Logging with SQLite |
| `CUSTOM_HOSTNAME` | localhost | Name for the local agent (running in the container with LAPI) |
