The equavelant to the non-conventional legacy settings:
```bash
DSPACE_UI_HOST => DSPACE_HOST
DSPACE_UI_PORT => DSPACE_PORT
DSPACE_UI_NAMESPACE => DSPACE_NAMESPACE
DSPACE_UI_SSL => DSPACE_SSL
```
The same settings can also be overwritten by setting system environment variables instead, E.g.:
```bash
export DSPACE_HOST=api7.dspace.org
export DSPACE_UI_PORT=4200
```
The priority works as follows: **environment variable** overrides **variable in `.env` file** overrides external config set by `APP_CONFIG_PATH` overrides **`config.(prod or dev).yml`**
