Phusion provides really awesome docker for the community. I used its baseimage as well as the passenger-full, which I later ran into some problems. I reckon that it'd be good to share some lessons that I learnt.

It can be various issues
It's just a document issue. The user need to be unlocked before you can login using a private key file. Otherwise sshd won't let you in.
RUN usermod -U app
appaccess even though it shows accessible mode. Deleting and re-add it will address the issue.
The overall part is
RUN usermod -U app ADD authorized_keys /tmp/authorized_keys RUN rm -rf /home/app/.ssh RUN install -m 700 -g app -o app -d /home/app/.ssh RUN install -m 600 -g app -o app /tmp/authorized_keys /home/app/.ssh/authorized_keys RUN install -m 600 -g root -o root /tmp/authorized_keys /root/.ssh/authorized_keys
