How Discourse deals with upgrades

[Ed_Siror]

I am a happy discourse user.
I would like to know how Discourse deals with upgrades so that I can implement something similar.
I know it is Docker-based!
Is it watchtower?

Discourse has a web UI for updates located at /admin/upgrade

Additionally, ./launcher can be used to rebuild discourse with latest code using
./launcher rebuild app

Are asking about how you might be able to create base images and deploy updates? Or do you want to duplicate what Launcher does for a different application?

Either way, then there are many topics about the different approaches. Just search for “docker compose” in this forum. But the best topic for you on updating with Discourse Launcher may be this one:

Can Discourse ship frequent Docker images that do not need to be bootstrapped?

There is this open issue (which I just closed) on Discourse Docker repo asking Discourse should behave like a standard docker image a docker user excepts to be able to run discourse without a special launcher. to define multiple containers (redis, postgres, discourse,…), links and volumes, docker-compose should be used instead. Docker Compose overview | Docker Docs The question is somewhat misguided, but I would like to address a broader one of Can Discourse ship frequent Docker images …

@itsbhanusharma, yes i was trying to duplicate the launcher or updater. I just realized that it is not that hard especially using Golang.
