How to run a pulled discourse image on digitalocean docker?

[wythhh]

Hi, I’m a newbie in docker and discourse and today I encountered a problem. I follow these two posts to install docker and discourse: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-18-04, How To Install Discourse on Ubuntu 16.04 | DigitalOcean.

After I set up my discourse, I did some modification on it, committed it to a docker image and pushed the image to dockerhub. Then I tried to pull the image from dockerhub and run it to get my discourse, but after I typed docker run my_image in terminal, it seemed this did not work. I googled online but did not find a good answer. Anyone has the idea on how to run this image? Thank you.

Direct modification of the image isn’t supported. Discourse can be modified in a supportable fashion through the app.yml and through plugins.

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. Overview of Docker Compose | Docker Documentation The question is somewhat misguided, but I would like to address a broader one of Can Discourse ship frequent Do…

Community supported official docker image

I really would like to have an official helm chart for discourse with an official docker image. I just opened this issue. I’d like to have the consent of the discourse maintainers to make this happening. Hope you can help make this happen. All you need to do is to give a yes Thanks!

The way to build an image is following the install cloud document. You don’t want to make changes to the code by hand. You’ll need to make a plugin (but lots of stuffyou can do in a theme).

It’s possible to build an image, push it to docker hub, and run it elsewhere, but if you’re just starting auth discourse, you don’t want to do that.
