CircleCI Plugin

Website: https://circleci.com/

Setup

1. If you have a standalone app (you didn't clone this repo), then do

# From your Backstage root directory
cd packages/app
yarn add @backstage/plugin-circleci

2. Add the EntityCircleCIContent extension to the entity page in your app:

// In packages/app/src/components/catalog/EntityPage.tsx
import {
  EntityCircleCIContent,
  isCircleCIAvailable,
} from '@backstage/plugin-circleci';

// For example in the CI/CD section
const cicdContent = (
  <EntitySwitch>
    <EntitySwitch.Case if={isCircleCIAvailable}>
      <EntityCircleCIContent />
    </EntitySwitch.Case>

4. Add proxy config:

# In app-config.yaml
proxy:
  '/circleci/api':
    target: https://circleci.com/api/v1.1
    headers:
      Circle-Token: ${CIRCLECI_AUTH_TOKEN}

5. Get and provide a CIRCLECI_AUTH_TOKEN as an environment variable (see the CircleCI docs).
6. Add a circleci.com/project-slug annotation to your respective catalog-info.yaml files, on the format // (https://backstage.io/docs/architecture-decisions/adrs-adr002#format).

# Example catalog-info.yaml entity definition file
apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
  # ...
  annotations:
    # This also supports bitbucket/xxx/yyy
    circleci.com/project-slug: github/my-org/my-repo
spec:
  type: service
  # ...

Features

• List top 50 builds for a project
• Dive into one build to see logs
• Polling (logs only)
• Retry builds
• Works for both project and personal tokens
• Pagination for builds

Limitations

• CircleCI has pretty strict rate limits per token, be careful with opened tabs
• CircleCI doesn't provide a way to auth by 3rd party (e.g. GitHub) token, nor by calling their OAuth endpoints, which currently stands in the way of better auth integration with Backstage (https://discuss.circleci.com/t/circleci-api-authorization-with-github-token/5356)
