Down after Docker Update

Just tried to update Docker in the Discourse admin area. I got an error and now my site is down. I haven’t made any changes to the site recently, so I’m a little confused as to what happend. What is the best way to recover in this situation? I have automated Discourse backups saved in the cloud, should I just reinstall Discourse and load my backup or is there an easier way to fix this?

I strongly suspect you ran out of memory here. Try making the instance larger or add some swap.

Try upgrading from the console first:

We are definitely seeing a number of “killed” out of memory support problems due to the latest Docker Manager changes w/r/t forking @sam… how do you want to handle this?

Derp, I should have thought of that. I just rebuilt and my site is back up, thanks!

cd /var/discourse
./launcher rebuild app

Maybe so, but I’ve never had that issue before. I’ve had this site for over a year on 1024 MB of memory.

Check dmesg to see if your oom-killer ran, that’ll let you know for sure.

How about we make the new upgrade behavior gated on an environment variable, set by ./discourse-setup for systems with >3GB RAM?

templates/web.template.yml:
env:
  DISCOURSE_GRACEFUL_UPGRADE: false

containers/app.yml:
env:
  # Set to true on systems with at least 3GB RAM.
  DISCOURSE_GRACEFUL_UPGRADE: false
