daytona

Welcome to the daytona plugin!

This plugin was created through the Backstage CLI

Description

The Daytona plugin provides frontend components to connect to the Daytona API backend and view the workspaces for the authenticated user. You can create new Daytona workspaces directly from Backstage.

Features

• Authenticate the user with Daytona Keycloak
• List all the workspaces for the authenticated user
• List workspaces of a specific repository for the authenticated user with appropriate annotations
• Create a new workspace by navigating to the Daytona instance

Installation

The package shall be installed in the Backstage root directory as below.

yarn --cwd packages/app add @adityasinghal26/backstage-plugin-daytona

Setup

Standalone App requirements

1. Install the plugin dependency in your Backstage app package:

   # From your Backstage root directory
   yarn add --cwd packages/app @adityasinghal26/backstage-plugin-daytona

2. Add to the app EntityPage component. Make sure to add DaytonaOverviewComponent right after EntityAboutCard under overviewContent. This will get the repository URL automatically from the entity location metadata to create the Daytona workspaces. Along with that, it will also list all the workspaces, specific to the repository.

   import { DaytonaOverviewContent } from '@adityasinghal26/backstage-plugin-daytona';
   
   // Add the DaytonaOverviewContent to show the workspaces for that entity
   const overviewContent = (
     <Grid container spacing={3} alignItems="stretch">
       <Grid item md={6}>
         <EntityAboutCard variant="gridItem" />
       </Grid>
       <Grid item md={6}>
         <DaytonaOverviewContent />
       </Grid>
       {/* other grid items here*/}
     </Grid>
   );

3. Annotate your component with a valid Git repository if you wish to override the automatically configured repository URL for creating Daytona workspaces.

   The annotation key is daytona.io/repo-url.

   Example:

   apiVersion: backstage.io/v1alpha1
   kind: Component
   metadata:
     name: backstage
     description: backstage.io
     annotations:
       daytona.io/repo-url: https://github.com/daytonaio-templates/go
   spec:
     type: website
     lifecycle: production
     owner: user:guest

App Menu requirements

Ensure that the package is installed as mentioned in the Installation section.

1. Add to the app App.tsx component:

   // In packages/app/src/App.tsx
   import { DaytonaPage } from '@adityasinghal26/backstage-plugin-daytona';
   
   // Add the route to the App path routes
   const routes = (
     <FlatRoutes>
     {/* other routes here */}
         <Route path="/daytona" element={<DaytonaPage />} />
     </FlatRoutes>
   );

2. Add to the app Root.tsx component:

   // In packages/app/src/components/Root/App.tsx
   import { DaytonaIcon } from '@adityasinghal26/backstage-plugin-daytona';
   
   // Add the menu to the Root menu sidebar
   export const Root = ({ children }: PropsWithChildren<{}>) => (
     <SidebarPage>
       <Sidebar>
       {/* other sidebar items here */}
       {/* add inside "Menu" SidebarGroup */}
         <SidebarItem icon={DaytonaIcon} to="daytona" text="Daytona" />
       {/* other sidebar items here */}
       </Sidebar>
       {children}
     </SidebarPage>
   );

Configuration

This plugin requires the domain URL for your Daytona instance. This can be configured in app-config.yaml file as per below snippet.

daytona:
  domain: daytona.domain.com

CORS Configuration for connecting Daytona APIs with Backstage

Below configurations need to be added in the 'watkins' ingress YAML which allows CORS connectivity. It allows Daytona URL along with Backstage URL for CORS policy.

    nginx.ingress.kubernetes.io/cors-allow-credentials: "true"
    nginx.ingress.kubernetes.io/cors-allow-headers: Authorization, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Origin, Content-Type, Accept, X-Requested-With

   auth:
    environment: production
    providers:
      daytona:
        production:
          clientId: <daytona-client-id>
          clientSecret: <daytona-client-secret>
