hooks for Discourse app.yml to load a custom Discourse repo into the docker image

hooks-app.yml

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/docker_manager.git
    - exec:
        cd: $home
        cmd:
          - git remote remove origin
          - git config --remove-section branch.master
          - git config --remove-section branch.tests-passed
          - git remote add origin https://github.com/scossar/discourse-custom
          - git fetch
          - git remote set-branches --add origin auto-rtl
          - git branch -u origin/auto-rtl
          - git reset --hard origin/auto-rtl

Replace 'hooks' section of /var/discourse/containers/app.yml with this to load a custom repo.
Change repo name https://github.com/scossar/discourse-custom and branch name auto-rtl to load your own repo. This repo will change soon.
Remember - no tabs in yaml - wrong indentation will break it!
