+## Docker Secrets
+
+The following variables support the use of [Docker secrets](https://docs.docker.com/engine/swarm/secrets/) for additional security.
+
+To use any of these, replace the regular environment variable with the equivalent `_FILE` environment variable. The value of
+the `_FILE` variable should be set to the path of a file containing the variable value.
+
+|  Regular Variable  | Equivalent Docker Secrets '\_FILE' Variable |
+| :----------------: | :-----------------------------------------: |
+|   `DB_HOSTNAME`    |      `DB_HOSTNAME_FILE`<sup>\*1</sup>       |
+| `DB_DATABASE_NAME` |    `DB_DATABASE_NAME_FILE`<sup>\*1</sup>    |
+|   `DB_USERNAME`    |      `DB_USERNAME_FILE`<sup>\*1</sup>       |
