How to Install Discourse Plugins Hosted in Private Repositories Using SSH Key?

[NateDhaliwal]

IIRC there are problems if you clone directly (I think this), that’s why using the tokens to clone are the recommended way.

But I think you may want to give this a shot, if you want to use SSH keys:

@Discourse

We strongly advise you to use OAuth tokens for plugins in private repositories. However, if you cannot, see below.

SSH Key Private Install Steps

• Assuming that your private git repo is hosted on GitHub, you need to add your server’s user public SSH key to GitHub repo Deploy keys (https://github.com/SecretOrg/secret-plugin/settings/keys).
• Modify app.yml file as shown in below example:

run:
  - exec: echo "Beginning of custom commands"
  
  - exec: cd /var/www/discourse && sudo -u discourse bundle install --deployment --without test --without development
  - exec: echo "Host github.com\n\tStrictHostKeyChecking no\n" >> /user/.ssh/config
  - file:
      path: /user/.ssh/id_rsa
      chmod: 600
      contents: |
        -----BEGIN RSA PRIVATE KEY-----
        MIIEogIBAAKCAQEArCQG213utzqE5YVjTVF5exGRCkE9OuM7LCp/FOuPdoHrFUXk
           .... etc ....
        -----END RSA PRIVATE KEY-----
  - file:
      path: /user/.ssh/id_rsa.pub
      chmod: 600
      contents: ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAklOUpkDHrfHY17SbrmTIpNLTGK9Tj .... etc .... user@discourse
  - exec: cd $home/plugins && git clone git@github.com:SecretOrg/secret-plugin.git
  - 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/id_rsa.pub

  - 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.
