I’m looking at automating upgrades of discourse. This is for the most basic single container install. Trying to keep things simple. The most basic would be to setup up this to run via cron: cd /var/discourse git pull ./launcher rebuild app Problem is you take the service offline for the rebuild e…

I’d suggest looking into how GitHub - discourse/docker_manager: Plugin for use with discourse docker image works. It compares the running version to GitHub, and updates with close to no downtime. Perhaps you can automate that instead of doing a full rebuild each time?

You might check out having separate data and web containers. That way you don’t need to take the site down to build a new image.

Yes, very good point. Thank you!
