The only officially supported installs of Discourse are the Docker based beginner and advanced installs. We regret that we cannot support any other methods of installation.

Why do you only officially support Docker?

Hosting Rails applications is complicated. Even if you already have Postgres, Redis and Ruby installed on your server, you still need to worry about running and monitoring your Sidekiq and Rails processes. Additionally, our Docker install comes bundled with a web-based GUI that makes upgrading to new versions of Discourse as easy as clicking a button.

Hardware Requirements

  • Dual core CPU recommended
  • 1 GB RAM minimum (with swap)
  • 64 bit Linux compatible with Docker

Software Requirements

  • Postgres 9.3+
  • Redis 2.6+
  • Ruby 2.0+ (we recommend 2.0.0-p353 or higher)
