Crossplane Claim Updater Plugin

Welcome to the crossplane-claim-updater plugin!

The Crossplane Claim Updater plugin provides a form component for updating Crossplane claim manifests in Git repositories. It uses the OpenAPI schema from the corresponding XRD to generate a dynamic form for updating claim specifications.

Features

• Dynamic form generation based on XRD OpenAPI schemas
• Support for GitHub repositories through Backstage's SCM integration
• Automatic PR creation with changes
• Support for both entity annotations and manual URL input
• Preserves file paths and directory structure

Installation

From your Backstage root directory, run:

yarn add --cwd packages/app @terasky/backstage-plugin-crossplane-claim-updater

Adding the plugins field extension to your Backstage apps scaffolder route:

// packages/app/src/App.tsx
import { GitClaimUpdaterExtension } from '@terasky/backstage-plugin-crossplane-claim-updater';
import { ScaffolderFieldExtensions } from '@backstage/plugin-scaffolder-react';

const routes = (
  <FlatRoutes>
    ...
    <Route path="/create" element={<ScaffolderPage />}>
      <ScaffolderFieldExtensions>
        <GitClaimUpdaterExtension />
      </ScaffolderFieldExtensions>
    </Route>
    ...
  </FlatRoutes>
);

Integrate the plugin with the entity scaffolder plugin:

// packages/app/src/components/catalog/EntityPage.tsx
import { GitClaimUpdaterExtension } from '@terasky/backstage-plugin-crossplane-claim-updater';
import { ScaffolderFieldExtensions } from '@backstage/plugin-scaffolder-react';

const crossplaneEntityPage = (
  <EntityLayout>
    ...
    <EntityLayout.Route path="/scaffolder" title="Entity Scaffolder">
        <EntityScaffolderContent
          templateGroupFilters={[
            {
              title: 'Management Templates',
              filter: (entity, template) =>
                template.metadata?.labels?.target === 'component' &&
                entity.metadata?.annotations?.['backstage.io/managed-by-location']?.split(":")[0] === 'cluster origin',
            },
          ]}
          buildInitialState={entity => ({
              entity: stringifyEntityRef(entity)
            }
          )}
          ScaffolderFieldExtensions={
            <ScaffolderFieldExtensions>
              <RepoUrlPickerFieldExtension />
              <EntityPickerFieldExtension />
              <GitClaimUpdaterExtension />
            </ScaffolderFieldExtensions>
          }
        />
    </EntityLayout.Route>
    ...
  </EntityLayoutWrapper>
);
