### Reading secrets from a file (`_FILE` suffix)
For any variable marked "Supports `_FILE`" above, you can set `<VARIABLE>_FILE` instead of `<VARIABLE>` to a path on disk, and Pangolin will read that file and use its (trimmed) contents as the value. This is the standard way to consume [Docker/Swarm secrets](https://docs.docker.com/engine/swarm/secrets/) — for example a secret mounted at `/run/secrets/server_secret` — without ever putting the raw value in `config.yml`, a `.env` file, or the container's visible environment.
Setting both `<VARIABLE>` and `<VARIABLE>_FILE` at the same time is an error.

## Environment Variables
Some configuration values can be set using environment variables for enhanced security:
| Name | Variable | Config | Supports `_FILE` |
|------|----------|--------|:---:|
| Redis Password | `REDIS_PASSWORD` | `redis.password` | ✅ |
Any variable marked "Supports `_FILE`" can also be set as `<VARIABLE>_FILE`, pointing to a file on disk whose (trimmed) contents are used as the value instead — see [Reading secrets from a file](/self-host/advanced/config-file#reading-secrets-from-a-file-_file-suffix) in the main configuration file docs for details and a Docker Compose example.
