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

This plugin contains a collection of actions:

• azure:pipeline:create
• azure:pipeline:run
• azure:pipeline:permit

It utilizes Azure DevOps REST APIs to create, run, and authorize Azure pipelines.

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-pipelines

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

// packages/backend/src/plugins/scaffolder.ts

import {
  createAzurePipelineAction,
  permitAzurePipelineAction,
  runAzurePipelineAction,
} from "@parfuemerie-douglas/scaffolder-backend-module-azure-pipelines";

const actions = [
  createAzurePipelineAction({ integrations }),
  permitAzurePipelineAction({ integrations }),
  runAzurePipelineAction({ integrations }),
  ...createBuiltInActions({
    containerRunner,
    catalogClient,
    integrations,
    config: env.config,
    reader: env.reader,
  }),
];

return await createRouter({
  containerRunner,
  catalogClient,
  actions,
  logger: env.logger,
  config: env.config,
  database: env.database,
  reader: env.reader,
});

The Azure pipeline actions use an Azure PAT (personal access token) for authorization. The PAT requires Read & execute permission for Build for the azure:pipeline:create and azure:pipeline:run actions. For the azure:pipeline:permit action the PAT requires Read, query, & manage permission for Service Connections. Simply add the PAT to your app-config.yaml:

# app-config.yaml

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

Read more on integrations in Backstage in the Integrations documentation.

Using the template

After loading and configuring the Azure pipeline template actions, you can use the actions in your template:

        project: ${{ (parameters.repoUrl | parseRepoUrl)['owner'] }}
        folder: "my-azure-pipelines-folder"

    - id: register
      name: Register
      action: catalog:register

        catalogInfoPath: "/catalog-info.yaml"

  output:
    links:
      - title: Repository
        url: ${{ steps.publish.output.remoteUrl }}
      - title: Pipeline
        url: ${{ steps.createAzurePipeline.output.pipelineUrl }}
      - title: Open in catalog
        icon: catalog
        entityRef: ${{ steps.register.output.entityRef }}

Note: The azure:pipeline:permit action authorizes/unauthorizes a pipeline for a given resource. To authorize a pipeline for a service endpoint set resourceType to endpoint, provide resourceId with the service endpoint ID (replace <serviceEndpointId> in the example code above), and set authorized to true.

You can find a list of all registred actions including their parameters at the /create/actions route in your Backstage application.
