Discourse does not officially provide a Docker image to run their forum software, which makes it harder to install on Coolify.

Solution:

Use the Bitnami Discourse Docker Image with a custom docker-compose file.

⚠️
Make sure to replace the following placeholders👇
PASSWORD_YOUR_DISCOURSE_PASS (all occurrences)
PASSWORD_YOUR_PG_PASS (all occurrences)

Passwords placeholders

  - DISCOURSE_HOST=yourdomain.com (all occurrences)
  - [email protected]
  - DISCOURSE_SITENAME=Forum

Branding placeholders

  - DISCOURSE_SMTP_HOST=in-v3.mailjet.com
  - DISCOURSE_SMTP_PORT=587
  - DISCOURSE_SMTP_USER=YOUR_MAILJET_USER
  - DISCOURSE_SMTP_PASSWORD=YOUR_MAILJET_PASSWORD

Email/SMTP placeholders
