Rebuilding the container is constantly failing after following the standard instructions on plugin install

We are running standard install of Discourse on DO. Everything was ok. then we decided to add 1 plugin by following this

by adding line

    - exec:
        cd: $home/plugins
          - sudo -E -u discourse git clone && sudo -E -u discourse git clone

container is failing to be rebuilt.

Pups::ExecError: echo "End of custom commands failed with return #<Process::Status: pid 5121 exit 2>
Location of failure: /usr/local/lib/ruby/gems/3.2.0/gems/pups-1.2.1/lib/pups/exec_command.rb:132:in `spawn'
exec failed with the params "echo \"End of custom commands"
bootstrap failed with exit code 2

all commands were ran as root. I think that there the issue is

I, [2024-04-18T04:28:49.985355 #1]  INFO -- : > cd /var/www/discourse/plugins && sudo -E -u discourse git clone && sudo -E -u discourse git clone
Cloning into 'docker_manager'...
warning: unable to access '/root/.config/git/attributes': Permission denied

Please advise here

Try it without this.

I just have - git clone ...

… and that’s worked for years!

It says access denied. Are you sure you’re running as root?

I am following the install guide that published here as official Discourse plugin install guide. All plugins have a link to this guide. In my case it destroyed our install and we even can not recover it, rebuilt it even under initial yml settings.

I am pretty sure that we ran it under root. After following the instruction our install was killed and we can not rebuild it even under initial yml settings.

A failed build should not destroy anything, it will just take you offline for a bit.

The database will still be intact.


Will a

 ./launcher start app

get the forum running?

My best guess is that you inserted a tab or something else that makes the yml invalid.

The error is about the “echo” at the very end of the yml file, which suggests that there’s a formatting issue somewhere before that.

Did you save a copy of the file before you edited it, or have you attempted to edit it to restore it to what you think its state was before you edited it?

A thing you can try is to rename your app.yml, take note of the values (especially the SMTP stuff) and run ./discourse-setup again. That’ll give you a working app.yml.


this starts the forum.
Will running ./discourse-setup keep the existing forum data or I should backup first and restore it? Many thanks for your support

Yes. The existing database and such will stay in place. This is just a way to make a new app.yml.

Dear @pfaffman and @merefield thank you for your support.
there were 2 issues:

  1. critical - mistake in YML syntax, fixed by YML validator
  2. less critical - replacing sudo -E -u discourse with just git clone (under root)

that helps us to rebuild and install plugin

thanks you so much,
