This is a small Docker container with openSUSE 13.2 as base system and everything for using the Open Build Service command line tool (OSC).
To use this container simply pull it from the docker repository:
docker pull jaltek/docker-opensuse-osc-client
followed by
docker run -ti --name=osc jaltek/docker-opensuse-osc-client /bin/bash
to enter the container. As OSC is already installed you are now able to interact with OBS.
