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 Chaos Engineering 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

This plugin exports a UI tab that you can use as a new "Chaos Experiments" tab for Chaos Engineering Experiments or for any other layout page. Go to Admin > Layout, select Service in the dropdown menu, and then add the following YAML code as a new section as we do for the CI/CD section:

- name: chaos
  path: /chaos
  title: Chaos Experiments
  contents:
    - component: EntitySwitch
      specs:
        cases:
          - if: isHarnessChaosAvailable
            content:
              component: EntityHarnessChaosContent

The isHarnessChaosAvailable condition is met when harness.io/project-url and harness.io/network-map-tags annotations are present in the software components's catalog-info.yaml definition file.

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:
    harness.io/project-url: <harness_project_url>
    harness.io/network-map-tags: |
      <nm-name_1>: <nm-label_1>
      <nm-name_2>: <nm-label_2>
spec:
  type: service
  # ...
