Beginners Guide to Install Discourse for Development using Docker

IMHO these related posts should be a separate topic so that it is not lost if these post become automatically deleted, but also because for those of us that developer or plan to develop plug-ins this is a howto (must know) topic.

Hi,

I have followed the instructions but app is not running rather its giving this error in browser console.
“ReferenceError: Discourse is not defined”
Looking for the solution.
Thanks

I’ve been running for 6 months or so in this configuration but today my usual workflow in docker fails with a message that Discourse can’t connect to the database.

Is there some issue caused by the recent Postgres 13 upgrade?

After many failed attempts I decided to re-do the boot init. I’ve removed all discourse_dev containers and have run:

bletch@BletchUbuntu:~/RubymineProjects/discourse$ git pull

I’ve tried entering the container as root and running psql but it yields.

root@discourse:/# psql 
psql: error: could not connect to server: No such file or directory
	Is the server running locally and accepting
	connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

The Postgres inside the container has indeed been updated.

root@discourse:/# psql -V
psql (PostgreSQL) 13.1 (Debian 13.1-1.pgdg100+1)

Any pointers?

Not sure if it is the same issue, but I got a similar problem and was due to permissions on some files in the container that postgres couldn’t access and, hence, wouldn’t start. The hint for that was on postgres logs — have a look at those perhaps?

Thanks for the suggestion @mentalstring . Oddly, the Postgres main log /var/log/postgresql/postgresql-13-main.log is empty.

But there is a clue in some of the other files under the /var/log/ structure. The file /var/log/postgres/current is completely filled with repeated errors like this.

2020-12-11 20:06:34.875 UTC [11680] FATAL:  database files are incompatible with server
2020-12-11 20:06:34.875 UTC [11680] DETAIL:  The data directory was initialized by PostgreSQL version 12, which is not compatible with this version 13.1 (Debian 13.1-1.pgdg1
00+1).

Some judicious Googling reveals that the raw DB format is incompatible and that a pg_upgrade command needs to be run.

I can’t see that command in PATH. Either way, a further bit of Googling reveals that Docker-based system struggle with this as both the old and new versions of Postgres need to be present for it to work.

Some further questions for anyone that can help

  • Is this a fundamental problem with using Docker in development for this upgrade?
  • Did I somehow miss a step?
  • Can I convert now?
  • Last resort how can I nuke the current data so boot_dev --init re-creates the database at Postgres 13?

Thanks in advance.

This bit is mentioned on the first post:

I followed this installation on a VPS, but I’m having trouble accessing the newly installed discourse. I tried accessing discourse from my VPS’ IP followed by the port 9292 with no luck. I believe the exposed port is different due to the docker interface.

Edit:
Nevermind I forgot to expose the ports globally on docker.

I set up a development environment at the beginning of this year to build a plugin. Now I want to make sure the plugin still works on the latest version of Discourse. Am I better off creating a new development environment from scratch (new docker container, database, etc.), or is it simple to get the latest version working from such an old build? I hear from time to time about database migrations in production environments, so that’s what I’m most unsure about. If I stick with my current environment, after I pull from git, what do I have to do?

bundle install
rake db:migrate

Should do it

I’m not able to get this working. I pulled the latest from the master branch, and then here’s what I did:

  1. d/boot_dev (works)
  2. d/bundle install (works)
  3. d/rails db:migrate RAILS_ENV=development as indicated in the OP, or d/rake db:migrate as you recommended (neither of them work)

Here’s the error I get for one of them (the other is basically the same):

rails aborted!

Tasks: TOP => db:migrate => db:load_config => environment

Besides it sounding like it can’t connect to the database, I have no idea what any of this means. I don’t even know how to tell if a database migration is even necessary, other than me assuming it is from chatter on the forums over the last year.

Once this failed I figured I’d try just running d/unicorn in case the database migration wasn’t relevant, but that also failed with the following error at the end:

/usr/local/lib/ruby/gems/2.7.0/gems/pg-1.2.3/lib/pg.rb:58:in `initialize': could not connect to server: No such file or directory (PG::ConnectionBad)
	Is the server running locally and accepting
	connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

So it seems to be the same issue effectively. Any suggestions for how to fix this connection issue or anything else that you may notice being wrong based on the traces?

See my post above.

It might be related.

My sense was that my problem was related to a migration to Postgres 13 that is automated on full installs but doesn’t get run on development. (an assumption).

See my followup post.

In the end I went nuclear, recreated the data and restored.

Yeah, I don’t really have any data worth keeping anyway. So clearing all the data is probably the simplest approach if that’ll work. Was just running sudo rm -fr data and d/boot_dev --init again sufficient to gets things back up and running? I’m not sure what you mean by “restored” though if you could clarify that part.

Yeah, I did have data I needed so cleared the data down and did a RESTORE from backup.

I did get my environment working again by deleting data and reinitializing, so now I can use the app including the plugin I was testing. However, I’m getting an error when I run tests against my plugin and another plugin that I tried to make sure it wasn’t just mine. I posted a separate topic about it, but I’m not sure if it’s related to my docker setup, so I wanted to cross-post here.

I am using Ubuntu WSL 2 in windows.

When I run:
d/boot_dev --init

nothing happens. It just starts a new line, with no execution signs. Any idea what’s going on here? Docker and git installed though.

Thank you.

  1. You installed Docker within WSL 2 and not on Windows itself, right?
  2. What directory are you running the command from? It should be from the top-level directory in the discourse repo.

Yes, I did install docker in both windows as well as inside Ubuntu WSL 2.
And I did run the command from /discourse directory.
But nothing shows up when I press return.

Not even any error logs or anything. So, it’s quite frustrating to know where to start from.

Hi all, question: if I use Digital Ocean’s one-click install (https://marketplace.digitalocean.com/apps/discourse) is this considered a developing environment? I’m sorry in advance for my ignorance, but I’m having trouble understanding what separates production from developing environments, and I’d like to start the long slow journey on learning plugin development.

A few things: (1) I have and old mac (2012) with an old OS (10.12.6), and I can’t manually install via terminal all that is needed for a local installation of discourse – I have to build much from source, and eventually I run into a “make” that never ends, and (2) I have successfully created discourse forums on one-click DO droplets in the past, but only for production – not development.

Any and all help/guidance/advice would be much appreciated!

Hello!

I have managed to install Discourse on Windows using WSL.

Prerequisites that i have done.

  • Enable WSL with version 2
  • I am using Ubuntu 20.04
  • Set up your distribution :slight_smile: Follow the given instructions and you are ready to go

In the distribution, under my home home folder, /home/cosmin.

  • Install Docker as instructed in the first post. The installation part of docker.io was not necessary for me. I only executed sudo usermod -a -G docker $USER
  • After the Docker installation is complete, start the service with sudo docker service start and check it
  • cd discourse
  • Run d/boot_dev --init and wait to finish
  • Run in discourse folder, run d/unicorn and you are ready yo go

Note:
If the commands are reporting permissions error, try with sudo

Hope this helps :slight_smile:
Have a nice day or evening!
Cosmin

Thanks for sharing your setup; however, I don’t have Windows. I’m specifically curious about the one-click Digital Ocean setup – is it suitable for development?
