Tech Insights

The Tech Insights integration plugin for Soundcheck exposes facts from Tech Insight backend, allowing them to be used in Soundcheck checks.

Prerequisites​

Add the TechInsightsHubFactCollector to Soundcheck​

First, add the @spotify/backstage-plugin-soundcheck-backend-module-techinsights package:

yarn workspace backend add @spotify/backstage-plugin-soundcheck-backend-module-techinsights

Legacy Backend​

If you are still using the legacy backend, in packages/backend/src/plugins/soundcheck.ts, add the TechInsightsFactCollector:

  import { SoundcheckBuilder } from '@spotify/backstage-plugin-soundcheck-backend';
  import { Router } from 'express';
  import { PluginEnvironment } from '../types';
+ import { TechInsightsFactCollector } from '@spotify/backstage-plugin-soundcheck-backend-module-techinsights';

  export default async function createPlugin(
    env: PluginEnvironment,
  ): Promise<Router> {
    return SoundcheckBuilder.create({ ...env })
+     .addFactCollectors(
+       TechInsightsFactCollector.create({
+         discovery: env.discovery,
+         tokenManager: env.tokenManager,
+         logger: env.logger,
+       }),
+     )
      .build();
  }

New Backend System​

If you are using the New Backend System, you can just add the following:

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

backend.add(import('@spotify/backstage-plugin-soundcheck-backend'));
backend.add(import('@spotify/backstage-plugin-soundcheck-backend-module-techinsights'));
// ...

backend.start();

Consult the Soundcheck Backend documentation for additional details on setting up the Soundcheck backend.

Rate Limiting (Optional)​

This fact collector can be rate limited in Soundcheck using the following configuration:

soundcheck:
  job:
    workers:
      techinsights:
        limiter:
          max: 1000
          duration: 60000

In this example, the fact collector is limited to 1000 executions per minute.

This fact collector handles 429 rate limit errors from Tech Insights. Soundcheck will automatically wait and retry requests that are rate limited.

Using TechInsight facts in Soundcheck​

Soundcheck fact references for this plugin follow the format techinsights:default/<id> where <id> is the fact retriever identifier from Tech Insights.

For example, if there is a Tech Insights fact retriever with an ID of entityOwnershipFactRetriever, its Soundcheck fact reference would be techinsights:default/entityOwnershipFactRetriever.

Soundcheck fact references enable facts from Tech Insights to be used in Soundcheck check. Here is an example of a Soundcheck check that makes use of a fact from Tech Insights.

id: has-owner
rule:
  factRef: techinsights:default/entityOwnershipFactRetriever
  path: $.hasOwner
  operator: equal
  value: true

When this check is executed, it will pull the fact(s) with a fact retriever identifier of entityOwnershipFactRetriever from Tech Insights and perform the specified check logic on it.

Currently, the collection of facts from Tech Insights is not scheduled or cached. Tech Insights facts are only collected on demand, when a check using a Tech Insights fact is executed (which can be scheduled).
