Configuration​

Application configuration YAML​

No action required

This plugin requires a backend proxy configuration to make calls to Harness APIs with authentication. The following configuration is set by default and you do not need to change anything:

proxy:
  "/harness/prod":
    target: "https://app.harness.io/"
    pathRewrite:
      "/api/proxy/harness/prod/?": "/"
    allowedHeaders:
      - authorization

Secrets​

No secrets are required for this plugin because both IDP and Feature Flags are part of the Harness software delivery platform.

Delegate proxy​

No action required

This plugin does not require a delegate proxy to be set up.

Layout​

No action required

This plugin exports a UI tab that you can use as a new Feature Flags tab for a service or for any other layout page. The following configuration is set by default in Layout under Admin for Service and you do not need to change anything:

- name: feature-flags
  path: /feature-flags
  title: Feature Flags
  contents:
    - component: EntityHarnessFeatureFlagContent

Also, you could add a conditional like isHarnessFeatureFlagAvailable which is met when the harness.io/project-url annotation is present in the software component's catalog-info.yaml definition file.

- name: feature-flags
  path: /feature-flags
  title: Feature Flags
  contents:
    - component: EntitySwitch
      specs:
        cases:
          - if: isHarnessFeatureFlagAvailable
            content:
              component: EntityHarnessFeatureFlagContent

Annotations​

To configure the plugin for a service in the software catalog, set one or both of the following annotations in its catalog-info.yaml definition file:

apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
  # ...
  annotations:
    # mandatory annotation
    harness.io/project-url: <harness_project_url>
spec:

  # ...
