Mia-Platform Backstage Plugin Backend

@mia-platform/backstage-plugin-backend is a plugin for the Backstage backend app. It updates and inserts on the catalog of your Backstage application all the entities that can be found on your Mia-Platform console such as components, resources, systems etc. It also displays all these information on a dedicated page of the plugin.

Requirements

This plugin requires @mia-platform/backstage-plugin-frontend to display all the information retrieved by the backend plugin on a dedicated page.

Configuration

New backend system

• Install the plugin to your Backstage app:

yarn workspace backend add @mia-platform/backstage-plugin-backend

• In packages/backend/src/index.ts import the plugin and add it to the backend:

import miaPlatformModule from '@mia-platform/backstage-plugin-backend';

// ...

backend.add(import('@backstage/plugin-catalog-backend-module-scaffolder-entity-model'));
backend.add(import('@backstage/plugin-catalog-backend/alpha'));

// ...

backend.add(miaPlatformModule());

• Add to your app-config.yaml file the section for the configuration of support button and the Mia-Platform console

Under app add the configuration for the support button

support:
    url: https://github.com/mia-platform/backstage-plugin/blob/main/README.md
    items: 
      - title: Documentation
        icon: docs
        links:
          - url: https://github.com/mia-platform/backstage-plugin/blob/main/README.md
            title: Repository

And then the configuration for the Mia-Platform console:

miaPlatform:
  baseUrl: ...
  gitBaseUrl: ...
  authorizations:
    - authMode: 'BASIC'
      clientId: ...
      clientSecret: ...
      companyId: ...
    - authMode: 'JWT'
      clientId: ...
      kid: ...
      privateKeyPath: ...
      expirationTime: ...
      companyId: ...

• baseUrl: Mia Platform console url
• authorizations: array of service accounts to use to retrieve projects information

Legacy backend system

• Install the plugin to your Backstage app:

yarn workspace backend add @mia-platform/backstage-plugin-backend

• Create a new file packages/backend/src/plugins/mia-platform.ts with content:

import { MiaPlatformEntityProvider, createRouter } from '@mia-platform/backstage-plugin-backend/legacy';
import { Router } from 'express';
import { PluginEnvironment } from '../types';
import { CatalogBuilder, CatalogEnvironment } from '@backstage/plugin-catalog-backend';
import { ScaffolderEntitiesProcessor } from '@backstage/plugin-catalog-backend-module-scaffolder-entity-model';

export default async function createPlugin(
  env: PluginEnvironment,
  catalogEnv: CatalogEnvironment
): Promise<Router> {
  const builder = await CatalogBuilder.create(catalogEnv);

  builder.addProcessor(new ScaffolderEntitiesProcessor());

  const miaPlatformProvider = MiaPlatformEntityProvider.create(env.config, env.logger);
  builder.addEntityProvider(miaPlatformProvider);

  const { processingEngine } = await builder.build();

  await processingEngine.start();

  return await createRouter({
    logger: env.logger,
    miaPlatformEntityProvider: miaPlatformProvider,
  });
}

• In packages/backend/src/index.ts import the plugin and add the route to the plugin:

import miaPlatform from './plugins/mia-platform'

// ...

const miaPlatformEnv = useHotMemoize(module, () => createEnv('mia-platform'));

// ...

apiRouter.use('/mia-platform', await miaPlatform(miaPlatformEnv, catalogEnv));

• Add to your app-config.yaml file the section for the configuration of support button and the Mia-Platform console

Under app add the configuration for the support button

support:
    url: https://github.com/mia-platform/backstage-plugin/blob/main/README.md
    items: 
      - title: Documentation
        icon: docs
        links:
          - url: https://github.com/mia-platform/backstage-plugin/blob/main/README.md
            title: Repository

And then the configuration for the Mia-Platform console:

miaPlatform:
  baseUrl: ...
  gitBaseUrl: ...
  authorizations:
    - authMode: 'BASIC'
      clientId: ...
      clientSecret: ...
      companyId: ...
    - authMode: 'JWT'
      clientId: ...
      kid: ...
      privateKeyPath: ...
      expirationTime: ...
      companyId: ...

• baseUrl: Mia Platform console url

[!WARNING] The base URL must not end with a /

• authorizations: array of service accounts to use to retrieve projects information

Authorization

The authorization elements inside the array should match one of the following:

BASIC

• authMode: 'BASIC'
• clientId: clientId used by the service account
• clientSecret: clientSecret used by the service account
• companyId: companyId related to the service account

JWT

• clientId: clientId used by the service account
• kid: kid related to the service account to use
• privateKeyPath: path to the file with the private key
