Ghost Discourse integration

Support
1

I am grappling with establishing an integration between Ghost and Discourse.

Discourse is: 2.8.0.beta1, docker on Ubuntu - no nginx

I’m using traefik on a standalone system behind a single ip router - in a natted home lan. Traefik allows http/s routing.

Traefik is configured with a traefik_dynamic.toml rather than docker labels. There is no shared docker network. (If anyone is interested in the traefik config - please ping me - it works quite nicely as a reverse proxy).

Ghost is also the latest version ( 4.6.4) and runs on a separate host (both hosts are ubuntu VMs- VERSION="20.04.2 LTS (Focal Fossa), running on proxmox.

I have followed the variety of tutorial pages that are available on Ghost Doc site and Discourse forum.

Firefox web developer tools indicate that the page returns the following page source:

<div class="comment container small">

<div class="discourse-comments"></div>
    <script type="text/javascript">
     if (window.location.pathname.indexOf('/p/') < 0) {
      DiscourseEmbed = { discourseUrl: 'https://discourse.mydomain/', discourseEmbedUrl: 'https://ghost.mydomain/testing-new-stuff/' };

  (function() {
    var d = document.createElement('script'); d.type = 'text/javascript'; d.async = true;
    d.src = DiscourseEmbed.discourseUrl + 'javascripts/embed.js';
    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(d);
  })();
}
</script>
</div>

But no actual comments are returned. I can see that my discourse host returns embed.js but nada on the page. (sorry I’m not a web developer person).

So it seems that the script is getting through and returning nothing

Its a new discourse install and its still on training wheels (bootstrap mode). So there are hardly any topics yet

app.yml is appended below.

embedded host settings are ok I believe with discourse adminuser as username for topic creation, path allowlist is currently “”
I created a category testing and it is added to the Post to category.

Also added DISCOURSE_ENABLE_CORS: true to app.yml because that might help. I added the proxy and http://ghost.mydomain and http://ghost.mydomain to the cors origins.

Anybody able to offer advice on how might I debug this?

app.yml:

## The Docker container is stateless; all data is stored in /shared
volumes:
  - volume:
      host: /var/discourse/shared/standalone
      guest: /shared
  - volume:
      host: /var/discourse/shared/standalone/log/var-log
      guest: /var/log

## Plugins go here
## see https://meta.discourse.org/t/19157 for details
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git

## Any custom commands to run after building
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 "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"
