How do I open the Rails console in Discourse Docker in production mode?

I have tried to use the following commands to get to the console, but I am encountering a lot of errors when I run the command. Here is the input:

  docker run -i -t local_discourse/app:latest bash
  cd /var/www/discourse/
  RAILS_ENV=production bundle exec rails c

And here is the shortened output:

  root@d19b0a20422c:/var/www/discourse# RAILS_ENV=production bundle exec rails c
  Rails Error: Unable to access log file. Please ensure that /var/www/discourse/log/production.log exists and is chmod 0666. The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

Run rails c instead - this will open the console as the correct user in the correct mode.

You can also do this with rake and discourse (for /var/www/discourse/script/discourse).

I didn’t know about the discourse command. That’s cool. But I still cannot get it to work. I get the same giant error complaining about the lack of the log file, and not being able to connect to the database server.

You’re launching the container running a single command only: bash

That’s analogous to booting a VM in single user mode.

As Sam says, launch it normally and then ssh in.

Just a correction:

cd /var/discourse/
./launcher enter app
rails c

I added the bellow in app. yml, but it fails, how can I run rails c with out interacting I need to run it once. (I am using ansible to automate installation)

run:
  - exec: echo "Beginning of custom commands"
  # If you want to set the 'From' email address for your first registration, uncomment and change:
  # After getting the first signup email, re-comment the line. It only needs to run once.
  - exec:   rails r "u = User.create!(username: '{{ discourse_developer_username }}', email: '{{ discourse_developer_emails }}', password: '{{ discourse_developer_password }}', admin: true)"
