scaffolder-backend-module-azure-repositories

Welcome to the Microsoft Azure repository actions for the scaffolder-backend.

This plugin contains a collection of actions:

• azure:repo:clone
• azure:repo:push
• azure:repo:pr

Getting started

Create your Backstage application using the Backstage CLI as described here: https://backstage.io/docs/getting-started/create-an-app.

Note: If you are using this plugin in a Backstage monorepo that contains the code for @backstage/plugin-scaffolder-backend, you need to modify your internal build processes to transpile files from the node_modules folder as well.

You need to configure the actions in your backend:

From your Backstage root directory

# From your Backstage root directory
yarn add --cwd packages/backend @parfuemerie-douglas/scaffolder-backend-module-azure-repositories

Configure the actions (you can check the docs to see all options):

// packages/backend/src/index.ts
const backend = createBackend();

// ...

backend.add(import('@parfuemerie-douglas/scaffolder-backend-module-azure-repositories'))

The Azure repository actions use an Azure PAT (personal access token) for authorization. The PAT requires Read permission for Code for the azure:repo:clone action. For the azure:repo:push action the PAT requires Read & write permission for Code. Simply add the PAT to your app-config.yaml:

# app-config.yaml

integrations:
  azure:
    - host: dev.azure.com
      credentials:
        - personalAccessToken: ${AZURE_TOKEN}

Read more on integrations in Backstage in the Integrations documentation.
