Install Plugins in Discourse

So you want to install a plugin on your Discourse instance? Great, let’s get started!

:warning: The below advice to self install plugins only applies to self-hosted Discourse instances. If you are using a managed hosting service, the available plugins will be controlled by your hosting provider. For example, on our hosting these specific plugins are available by hosting tier.

In this tutorial, we’ll install Discourse Spoiler Alert plugin.

  • Copy the plugin’s GitHub or Bitbucket git clone url.

  • Access your container’s app.yml file (present in /var/discourse/containers/)

    cd /var/discourse
    nano containers/app.yml
  • Add the plugin’s repository URL to your container’s app.yml file:

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

    (Add the plugin’s git clone url just below sudo -E -u discourse git clone

  • Rebuild the container:

    cd /var/discourse
    ./launcher rebuild app

    That’s it, you’ve successfully installed the Discourse Spoiler Alert plugin on your Discourse instance!

Installing plugins hosted in a private repo

Use an OAuth token to install your plugin

This way you can install your plugin in the same space as any other and you don’t need to create an ssh key.

    - exec:
        cd: $home/plugins
              - sudo -E -u discourse git clone https://<token>

:bookmark_tabs: An alternative method to install private plugins can be to use SSH keys. However, for most instances, OAuth tokens is the preferred method.

SSH Key Private Install Steps
  - exec: echo "Beginning of custom commands"
  - exec: cd /var/www/discourse && sudo -u discourse bundle install --deployment --without test --without development
  - exec: echo "Host\n\tStrictHostKeyChecking no\n" >> /user/.ssh/config
  - file:
      path: /user/.ssh/id_rsa
      chmod: 600
      contents: |
        -----BEGIN RSA PRIVATE KEY-----
           .... etc ....
        -----END RSA PRIVATE KEY-----
  - file:
      path: /user/.ssh/
      chmod: 600
      contents: ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAklOUpkDHrfHY17SbrmTIpNLTGK9Tj .... etc .... user@discourse
  - exec: cd $home/plugins && git clone
  - exec: cd $home && sudo -E -u discourse bundle exec rake db:migrate
  - exec: cd $home && rm -fr tmp/cache
  - exec: cd $home &&  sudo -E -u discourse bundle exec rake assets:precompile
  - exec: rm /user/.ssh/id_rsa
  - exec: rm /user/.ssh/

  - exec: echo "End of custom commands"
  • Rebuild the container:
cd /var/discourse
./launcher rebuild app

Your private plugin should be installed on your Discourse instance.

Thanks, but that also does not show an example of additional plugins.

This video does: Install Plugins in Discourse (Formatting Toolbar) - YouTube

So the code example should read (as it talks about the Spoiler Alert plugin:

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

Without that addition, the example is incomplete. Sorry, don’t want to be a pain, but hope this helps others. As this comment will be deleted after 6 months, an edit of the Original post is the only way.
