I pushed the image on Docker Hub, so that deploying it is now as easy as:
docker pull phocean/msf
It is an automatic build based on the Github repository.
It means that the image is built by Docker, not by me. For this task, they simply have a read access to the Dockerfile on Github.
Thus, you may place in this image the same level of trust than the one you have in Docker (I cannot interfere in the process and mess with the image).
I say it because I am myself reluctant of installing third-party images. While I prefer to rebuild everything from Dockerfiles, I am fine with automatically built images if I am in a hurry and for non sensitive data.
