Chapter 5. Enabling and configuring the Nexus Repository Manager plugin

The Nexus Repository Manager plugin displays the information about your build artifacts in your Developer Hub application. The build artifacts are available in the Nexus Repository Manager.

5.1. Enabling the Nexus Repository Manager plugin

The Nexus Repository Manager plugin is pre-loaded in Developer Hub with basic configuration properties. To enable it, set the disabled property 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
Copy to Clipboard Toggle word wrap

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). This format is only applicable for Community supported plugins.

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

        # 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`
