For administrators

Installation and configuration

1. Install the Nexus Repository Manager plugin using the following command:

   yarn workspace app add @janus-idp/backstage-plugin-nexus-repository-manager

2. Set the proxy to the desired Nexus Repository Manager server in the app-config.yaml file as follows:

   proxy:
     endpoints:
       '/nexus-repository-manager':
         target: 'https://<NEXUS_REPOSITORY_MANAGER_URL>'
         headers:
           X-Requested-With: 'XMLHttpRequest'
           # Uncomment the following line to access a private Nexus Repository Manager using a token
           # Authorization: 'Bearer <YOUR TOKEN>'
         changeOrigin: true
         # Change to "false" in case of using self hosted Nexus Repository Manager instance with a self-signed certificate
         secure: true

3. Optional: Change the base URL of Nexus Repository Manager proxy as follows:

   nexusRepositoryManager:
     # default path is `/nexus-repository-manager`
     proxyPath: /custom-path

4. Optional: Enable experimental annotations:

   nexusRepositoryManager:
     experimentalAnnotations: true

   Replace the isNexusRepositoryManagerAvailable import with isNexusRepositoryManagerExperimentalAvailable when adding the <NexusRepositoryManagerPage /> component.

   NOTE: The annotations mentioned in this step are not thoroughly tested.

5. Enable an additional tab on the service entity page in packages/app/src/components/catalog/EntityPage.tsx:

   /* highlight-add-next-line */
   import {
     isNexusRepositoryManagerAvailable,
     NexusRepositoryManagerPage,
   } from '@janus-idp/backstage-plugin-nexus-repository-manager';
   
   const serviceEntityPage = (
     <EntityLayout>
       {/* ... */}
       {/* highlight-add-next-line */}
       <EntityLayout.Route
         if={isNexusRepositoryManagerAvailable}
         path="/build-artifacts"
         title="Build Artifacts"
       >
         <NexusRepositoryManagerPage />
       </EntityLayout.Route>
     </EntityLayout>
   );

   You may also wish to add the route to other component types, such as librarys.

6. Annotate your entity with any of the following annotations:

   metadata:
     annotations:
       # insert the chosen annotations here
       # example
       nexus-repository-manager/docker.image-name: `<ORGANIZATION>/<REPOSITORY>`,

   For more information about annotations, see the annotation file.
