Compile utilities in openfoam4-linux docker image?
 

I've been playing around with the OpenFOAM-4.1 docker image. It works great. Paraview works great. BUT, how in the heck to I add new utilities (i.e. perturbU, swak4foam, etc.) to the image? If I can't add to it, how do I copy and modify it?

I'm an idiot
 

Ok. Nevermind. Turns out you just download everything to the correct folder and run wmake while in the docker image. If anyone has any tips/tricks for working with the OpenFOAM docker images, I would love to hear them. Ultimately, it would be really nice to have a custom image that I can distribute to all of my different machines and keep all of them updated with a simple "git pull" like statement.
