discourse – blank page after update

Yah! that’s it.
I’v performed a discourse update and now my client’s discourse it’s blank page.
Source it’s there…. browser just shows a blank page.

Yah! Shitty plugin was my issue.
I/we are using babble – small chat plugin, lowly maintained -.
After disabling it on app.xml and rebuilt the app, it worked.

Install a plugin on discourse


One of my clients needs a plugin on his discourse installation!
First you need to update your discourse installation!

Then grab the GIT url from the plugin.


Let’s edit app.yml

nano /var/discourse/containers/app.yml

and add the url of plugin’s git (author recommends, for those with discourse running the latest version to use -b beta)

- git clone -b beta https://github.com/gdpelican/babble.git


Rebuild the container!

cd /var/discourse
./launcher rebuild app




discourse & cloudflare – show real users IP address

Discourse has a recent (5month old?) template to handle with this.

Lets add   – “templates/cloudflare.template.yml” to our templates scheme…

nano containers/app.yml

Save it and rebuild the app! 🙂

./launcher rebuild app

Discourse – email and Job exception: Net::ReadTimeout



For a Discourse instance to function properly Email must be set up. Use the SMTP_URL env var to set your SMTP address, see sample templates for an example. The Docker image does not contain postfix, exim or another MTA, it was omitted because it is very tricky to set up correctly.

Source: https://github.com/discourse/discourse_docker

Yah! Discourse doesn’t came with any MTA (mail transfer agent).
I had to install Postfix so that Discourse could send out emails.

My emails weren’t getting delivered…
I was getting the following error on discourse logs(/var/discourse/shared/standalone/log/rails/production.log)….

Job exception: Net::ReadTimeout

After a few tweaks… I got it working…
This is my /var/discourse/containers/app.yml excerpt….

## TODO: List of comma delimited emails that will be made admin and developer
 ## on initial signup example '[email protected],[email protected]'
 DISCOURSE_DEVELOPER_EMAILS: '[email protected]'

## TODO: The SMTP mail server used to validate new accounts and send notifications
 DISCOURSE_SMTP_ADDRESS: mail.domain.com
 DISCOURSE_SMTP_USER_NAME: [email protected]
Rebuild the APP
cd /var/discourse/
./launcher rebuild app
