Run Docker locally

When some "strange" pipelines fail building/testing cfs, it can make sense to run the docker images locally. This is a very brief howto:

  • install docker according the instructions for your OS

  • get the images from https://gitlab.com/openCFS/build-environment

  • go to the directory of the Dockerfile of interest (here centos7/intel) and build the image

    docker build --tag 'centos7_intel' . This does not create files in the present directory.

  • start the container for interactive use (user gitlab-runner, add --user root in case) via

    docker run -it 'centos7_intel' bash

  • within the virtual system you can e.g. git clone https://github.com/openCFS/cfs.git cfs then checkout your branch and build cfs

  • you can check running docker containers via

    docker ps

  • you can log into a running container via

    docker exec -it <hash> bash where the hash is from the docker ps output.
