Configuring auto discovery for your organization

Published on May 10th, 2022

Introduction

Roadie loads your catalog-info.yaml files automatically from GitHub. This document explains how to specify where those files are loaded from, how to decorate entities automatically with additional metadata, and how to support multiple organizations.

Prerequisites

  • You must have installed the Roadie GitHub app in your organisation as described here
  • You must be an Admin of Backstage

Steps to add new auto discovery paths

  1. Visit the Administration > Settings page and click on GitHub under Integrations
  2. Scroll down to the Automatically add and remove entities from your Catalog section. add and remove
  3. Press the + ADD URL button.
  4. In the input that appears enter a url that you’d like to have Roadie to listen for additions and deletions. This url accepts regex in every segment
  5. Press ADD

Steps to remove auto discovery paths

  1. Visit the Administration > Settings page and click on GitHub under Integrations
  2. Scroll down to the Automatically add and remove entities from your Catalog section. add and remove
  3. Press the DELETE sign next to the url under the actions column.
  4. Press DELETE

Example configs

Exact url

If you do not specify any wildcards it will load only the specified exact path.

https://github.com/RoadieHQ/roadie-backstage-plugins/blob/main/catalog-info.yaml

In this example, Roadie will only load a catalog-info.yaml file from the main branch when it gets added/removed from the repo roadie-backstage-plugins in the RoadieHQ organization.

Using the default branch

If you have default branch configured differently for your repos you can use the - sign as a substitution in your url and it will get replaced by your repo’s default branch.

https://github.com/RoadieHQ/roadie-backstage-plugins/blob/-/catalog-info.yaml

In this example, Roadie will only load a catalog-info.yaml file from the default branch when it gets added/removed from the repo roadie-backstage-plugins in the RoadieHQ organization.

Using wildcards

If you would like to catalog a file from all of your repos you can use the * as a wildcard in any of the segmenets.

https://github.com/RoadieHQ/*/blob/-/catalog-info.yaml

In this example, Roadie will load a catalog-info.yaml file from the default branch when it gets added/removed from any repo in the RoadieHQ organization.

Putting your catalog files inside a folder

You can specify a folder in the resource part of the URL any depth you would like. This gives the possibility to specify the following url.

https://github.com/RoadieHQ/*/blob/-/.roadie/*.yaml

In this example, Roadie will load any .yaml file inside a root level .roadie folder from the default branch when it gets added/removed from any repo in the RoadieHQ organization.

Confirming it worked

Add a Backstage component file to a repository which matches the configured discovery url. After committing it to the correct branch, you should see it almost immediately in your catalog.

Decorating Catalog Entities

You can add the primary language used by a repository as a tag or label to the Roadie Backstage entity without updating your yaml files by turning on the decoration feature in /administration/settings/catalog.

There will be a lag of a round 10 minutes for all entities to be tagged, and when turning it off, there will be a similar lag for the tags to be removed.

NB: This feature only adds the tag/label in Roadie’s representation of your catalog files, and does not modify the base yaml files in your repos.
