### Context
Wikibase docker bundle uses `wikibase.svc` as an alias for wikibase service. It is bound to port number 8181, and one can access wikibase instance locally
by navigating to `http://localhost:8181`, or after mapping wikibase.svc to loopback (in `/etc/hosts` in unix) by navigating to `http://wikibase.svc:8181`.
That alias `wikibase.svc` is used in other services in the bundle, like wdqs-frontend (https://github.com/wmde/wikibase-docker/blob/master/docker-compose.yml#L75) and wdqs (https://github.com/wmde/wikibase-docker/blob/master/docker-compose.yml#L87), to communicate with wikibase apis inside docker's internal network. That works because in the internal network, wikibase service is bound to port 80, so calling http://wikibase.svc would reach the backend successfully.
### Problem
As a result of configuring `WIKIBASE_HOST=wikibase.svc` on wdqs and wdqs-frontend services, the urls that are created for entities in query results are mapped to the domain `http://wikibase.svc/...`. Those urls, when clocked on, will not resolve properly as we are visiting them externally, and wikibase.svc is there's no service listening on port 80 that can capture that server name.
**Steps to reproduce**
1. check out https://github.com/wmde/wikibase-docker and boot it up with `docker-compose up -d`.
2. navigate to wikibase instance http://localhost:8181 and create a property and an entity.. attach that new property to the new entity with any value.
3. tear down the services with `docker-compose down` then boot them up again `docker-compose up -d`.
**note:** this is seems to be required for wdqs-updater if it was run first time with a wikibase instance that had no entities yet.. so in case you had already the bundle setup and wdqs-updater running properly you might not need this step.
4. navigate to query service front-end `http://localhost:8282` and run the following query (replace `<new property id>` with the new property id that you created in 2:
```
SELECT
?item ?itemLabel
WHERE
{
?item wdt:P<new property id> ?value
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}
LIMIT 10
```
5. you should see your new item appearing in the results
6. click on the item label/id in the results
**Suggested next steps**
* Check whether those links in query results come from wdqs-frontend or wdqs service (who generates them and how)
* Check if there's a reasonable way to make those links in query results resolve with the default setup. One possibility is to configuring the service generating those links with another variable that tells it what base url to use, and use it (for instance, one then can say WIKIBASE_EXTERNAL_URL=localhost:8181)
