I finally upgraded our discourse server (including OS & Docker).
I had to destroy and bootstrap again because of problems. It’s running v1.6.0.beta1 +178 now but I still see only this image:
root@disc:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE local_discourse/app latest 370fea60556d 36 minutes ago 1.635 GB samsaffron/discourse 1.0.8 76762729d2a1 13 months ago 1.143 GB
Is this correct?
