Docker Container for QGC Development

I’m trying to setup a docker container on Linux for QGC development. There is a github repo here which provides Dockerfiles for creating docker container. But when I try Dockerfile for Linux, it get stuck at Welcome Page.

$ git clone
$ cd containers
$ docker build -t qgc_dev -f Dockerfile_qgc-build-linux .


I’m not sure what to do at this stage!!

Any help is highly appreciated.
