Looking for Production Discourse Instructions

(Dan Healy) #1

I’m already running the following and need to understand how to configure a Discource container with a production environment:
-Postgres Server
-Nginx (reverse proxy for all sites)
-Docker cluster

My intention is to run a Discourse container and scale as needed. However, I need to protect data as done in production.

(Joshua Rosenfeld) #2

You will get most of the information you need from the Discourse Github repo and Discourse Docker Repo:
discourse/INSTALL.md at master · discourse/discourse · GitHub

I’d suggest reading through both in detail, then asking specific questions if you get stuck on something.

(Dan Healy) #3

I’ve read both pages in detail, as well as a ton of other information. Just a couple of points I’ll make:

  • In a production HA environment, it is not acceptable to have a single container run Rail,Redis, Postgresql, and Nginx.
  • It’s not clear to me if the current Discourse Docker solution will run properly on an existing Docker Cluster with many other containers already running
  • Our environment already has HA Postgresql, Redis, and a Docker Cluster - These should be leveraged
  • The Discourse rails app should have the ability to start with a ‘docker stack deploy’ function, not a ./launcher script.

I’ve run many rails containers before for enterprise applications. What I’m looking for is to understand if I’m going to need to build my own Discourse container (I hope not). And if not, where can I get the Discourse container (preferably from a ‘docker pull’ command) and start it with ‘docker stack deploy’ with a matching docker-compose.yml file.

I also need to know exactly what folders and files from inside the container I need to mount to the host (all our persistent data runs from a very fast NFS mount).

So, to recap, I intend to have a docker-compose.yml file that contains all the information to start the Discourse Rails app, including mounts, and the ability to scale replicas.

Sure, and we do not do that in our production instances, see: discourse_docker/samples at master · discourse/discourse_docker · GitHub

Runs fine for us

Nothing stopping you leveraging that pg and redis location are passed in via environment vars

This did not exist 3 years ago. So, yeah … maybe … but it would require a ton of new work.

Feel free to read through: Can Discourse ship frequent Docker images that do not need to be bootstrapped?

(Dan Healy) #5

Sam, I appreciate the info. I’ll read through all of it and let you know shortly.
Note: It seems to me that the work required here to make this type of solution available is to carefully read through ‘launcher’ and produce deployment instructions that include the creation process and docker-compose.yml. I plan on doing this because I need it for myself. I’ll host my instructions on my own github repo for this (which doens’t exist yet) and link it back here.


Did you get the chance to create that github repo with instructions?
