I encountered a few issues. One was definitely something to do with older postgres. From memory, I tried downgrading it using apt, but then other things played up and I put the project aside.
I followed Sam's suggestions to regenerate the Dockerfile with dockerfile-rails (btw, thanks for your work on dockerfile-rails, super excited about it) and solved a couple more issues, but I again ran out of steam when new issues kept coming and coming. I'm sure when I'm more comfortable with docker these will become trivial to solve.
These were not super determined attempts by me, more playing around. I look forward to more serious attempts when I'm more capable with docker.
