Currently, this is only supported for `NEXTCLOUD_ADMIN_PASSWORD`, `NEXTCLOUD_ADMIN_USER`, `MYSQL_DATABASE`, `MYSQL_PASSWORD`, `MYSQL_USER`, `POSTGRES_DB`, `POSTGRES_PASSWORD`, `POSTGRES_USER`, `REDIS_HOST_PASSWORD`, `SMTP_PASSWORD`, `OBJECTSTORE_S3_KEY`, and `OBJECTSTORE_S3_SECRET`.
If you set any group of values (i.e. all of `MYSQL_DATABASE_FILE`, `MYSQL_USER_FILE`, `MYSQL_PASSWORD_FILE`, `MYSQL_HOST`), the script will not use the corresponding group of environment variables (`MYSQL_DATABASE`, `MYSQL_USER`, `MYSQL_PASSWORD`, `MYSQL_HOST`).
# Make your Nextcloud available from the internet
Until here, your Nextcloud is just available from your docker host. If you want your Nextcloud available from the internet adding SSL encryption is mandatory.
