Chapter 5. Enable and configure the Nexus Repository Manager plugin

Use the Nexus Repository Manager plugin to view build artifacts in your Developer Hub application. You can find this community-sourced plugin in the Community plugins migration table.

5.1. Enable the Nexus Repository Manager plugin

To enable the Nexus Repository Manager plugin, set the disabled property to false.

Procedure

  • Set the value to false as follows: 

    global:
  dynamic:
    includes:
      - dynamic-plugins.default.yaml
    plugins:
      - package: oci://ghcr.io/redhat-developer/rhdh-plugin-export-overlays/backstage-community-plugin-nexus-repository-manager:<tag>
        disabled: false

    The <tag> variable is your RHDH application's version of Backstage and the plugin version, in the format: bs_<backstage-version>__<plugin-version> (note the double underscore delimiter).

  • To find the correct image tag for <tag>:

    1. Look in the RHDH release notes preface for your Backstage version.
    2. Locate the plugin version for paths starting with oci://ghcr.io within one of the tables in the Dynamic Plugins Reference guide.

For example, because RHDH 1.9 is based on Backstage 1.45.3, the tag will have the format bs_1.45.3__<plugin-version>.

Tip

To ensure environment stability, use a SHA256 digest instead of a version tag. See Determining SHA256 Digests.

Procedure

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

    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

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

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

  3. Optional: Enable the following experimental annotations: 

    nexusRepositoryManager:
    experimentalAnnotations: true

  4. Annotate your entity using the following annotations: 

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