Create and manage Coder workspaces from Backstage.

Screenshots

Features

• Users link their Coder accounts with Backstage via tokens
• Associate Coder workspaces with catalog items in Backstage
• Workspace list component for viewing and managing workspaces

Setup

This assumes you already have a Coder deployment running. Replace https://coder.example.com with your Coder deployment access URL. This also assumes you have a template that has a parameter for a git repository URL (e.g. git_repo_url) that auto-clones the repository or uses envbuilder to build the Dev Container.

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

   yarn --cwd packages/app add @coder/backstage-plugin-coder
   

2. Add the proxy key to your app-config.yaml:

   proxy:
     endpoints:
       '/coder':
         # Replace with your Coder deployment access URL and a trailing /
         target: 'https://coder.example.com/'
         changeOrigin: true
         allowedMethods: ['GET']
         allowedHeaders: ['Authorization', 'Coder-Session-Token']
         headers:
           X-Custom-Source: backstage
   

3. Add the CoderProvider to the application:

   // In packages/app/src/App.tsx
   import {
     type CoderAppConfig,
     CoderProvider,
   } from '@coder/backstage-plugin-coder';
   
   const appConfig: CoderAppConfig = {
     deployment: {
       accessUrl: 'https://coder.example.com',
     },
   
     // Set the default template (and parameters) for
     // catalog items. This can be overridden in the
     // catalog-info.yaml for specific items.
     workspaces: {
       templateName: 'devcontainers',
       mode: 'manual',
       // This parameter is used to filter Coder workspaces
       // by a repo URL parameter.
       repoUrlParamKeys: ['custom_repo', 'repo_url'],
       params: {
         repo: 'custom',
         region: 'eu-helsinki',
       },
     },
   };
   
   // ...
   
   export default app.createRoot(
     <CoderProvider appConfig={appConfig}>
       <AlertDisplay />
       <OAuthRequestDialog />
       <AppRouter>
         <Root>{routes}</Root>
       </AppRouter>
     </CoderProvider>,
   );
   

   Note: You can also wrap a single page or component with CoderProvider if you only need Coder in a specific part of your app. See our API reference (particularly the section on the CoderProvider component) for more details.

4. Add the CoderWorkspacesCard card to the entity page in your app:

   // In packages/app/src/components/catalog/EntityPage.tsx
   import { CoderWorkspacesCard } from '@coder/backstage-plugin-coder';
   
   // ...
   
   <Grid item md={6} xs={12}>
     <CoderWorkspacesCard readEntityData />
   </Grid>;
   

Roadmap

This plugin is in active development. The following features are planned:

• Add support for only rendering component if catalog-info.yaml indicates the item is compatible with Coder
• OAuth support (vs. token auth) for linking Coder accounts
• "Open in Coder" button/card component for catalog items
• Example creating workspaces with Backstage Scaffolder
• Example dedicated "Coder" page in Backstage
