**Motivation**
A 3rd party running their instance of Wikibase may want to dump RDFs from that instance for exporting it to another system.
**Problem**
Running the RDF export command described in the repo
```
docker-compose exec wikibase php ./extensions/Wikibase/repo/maintenance/dumpRdf.php
```
`conceptUri`s use hash-based in the ttl that is based on the docker container hash ID. see e.g. output in original description.
**Suggested Solution**
https://phabricator.wikimedia.org/T227643#5320426
>The solution is to add #wgServer with the proper value in LocalSettings.php
> To do that you need to add an entry such as ${DOLLAR}wgServer = "${SERVER}"; in the LocalSettings.php.template file as described here
> and add SERVER as an environment variable in the compose file
NOTE: The suggested solution above fixed the problem for the author. We want to include this in the image itself so that it is fixed for all future users.
