Docker Container for QGC Development

Hello,
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 https://github.com/mavlink/containers.git
$ cd containers
$ docker build -t qgc_dev -f Dockerfile_qgc-build-linux .

qgc_docker

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

Any help is highly appreciated.
