qlever: RPT/qlever with a docker-in-docker setup

[Aklakan]

I started this task some time ago but did not get it working.
The last commands in my personal history indicate that I tried to use --privileged and mounting the socket. I guess there were permission problems - but need to investigate closer and track progress here.

docker run --privileged=true -v /var/run/docker.sock:/var/run/docker.sock -v "$(pwd):/data" -w '/data/' -it aksw/rpt:latest-unstable integrate -e qlever --server --port 8888 dbpedia-1.0.0-dbpedia_2015-10.nt
