Because the testserver requires some services (such as solr, sablon, etc), it should be run with docker compose.
The docker compose.yml in the root of opengever.core includes the necessary definitions
for running the testserver in docker.
Start testserver:
$ cd opengever.core
$ docker compose up testserver
$ bin/testserverctl isolate
You can also run testserverctl from within docker:
docker compose exec testserver bin/testserverctl isolate
After executing the isolate command you can open http://localhost:55001/plone
$ cd opengever.core
$ docker compose build testserver
The image needs to be built manually at the moment. Published images may not be up to date.
