How to change the host that is used for entities in WDQS? Default is wikibase.svc, I want it to be localhost

The context

I'm running Wikibase locally for experimentation purposes. In this section, I describe the installation process that I followed for getting it running.

I downloaded the files in the example directory from the main branch as of the time of this writing (permalink to commit). I didn't made a single modification to these files.

• example/docker-compose-extra.yml (permalink)
• example/docker-compose.yml (permalink)
• example/extra-install.sh (permalink)
• example/jobrunner-entrypoint.sh (permalink)
• example/template.env (permalink)

I then ran the docker-compose command as shown below.

$ docker-compose -f docker-compose.yml -f docker-compose.extra.yml up -d

At this point, I could

• Create items in http://localhost/wiki/Special:NewItem (I created one to check)
• Create properties in http://localhost/wiki/Special:NewProperty (I created one to check)
• Visit WDQS in http://localhost:8834. Execute queries there (see screenshot below) and query the SPARQL endpoint with curl (see code block below).

$ curl \
  -G 'http://localhost:8834/proxy/wdqs/bigdata/namespace/wdq/sparql' \
  -H 'Accept: text/csv' \
  --data-urlencode query='
SELECT ?a ?b ?c {
  ?a ?b ?c.
}'

The problem

As you can see in the screenshot below, the URLs for the entities use wikibase.svc instead of localhost.

When I click in the link http://wikibase.svc/entity/P1 (second row in the results in the screenshot above), I see the following in Firefox.

When I click in the link http://wikibase.svc/entity/Q1 (third row in the results in the screenshot above), I see the following in Firefox.

The question

How to change the HOST that is used for the entities in WDQS?

I would expect these URLs to be http://localhost/entity/Q1 and http://localhost/entity/P1 instead of http://wikibase.svc/entity/P1 and http://wikibase.svc/entity/Q1.
