hcp-consul

This is a frontend plugin for viewing Hashicorp Cloud Platform(HCP) consul overview and service instances of a services. This plugin has a corresponding backend plugin required to call the HCP consul's API: @hashicorp/plugin-hcp-consul-backend.

Introduction

HCP Consul Central

HCP Consul Central is a management plane service hosted by HashiCorp that enables you to monitor and manage multiple Consul server clusters regardless of where the clusters are hosted.

Features

This plugin provides two items:

• a plugin page to view overview of the project
• a service instance component table

Getting started

Requirements

You will need to have the backend HCP consul plugin, @hashicorp/plugin-hcp-consul-backend, installed and running. See its README for set up instructions.

You will need clusters added in HCP Consul central. Learn more about HCP Consul Central.

You need to generate a service principal key. You can follow this tutorial to generate the clientID and client Secret.

Installation

# From your Backstage root directory
yarn add --cwd packages/app @hashicorp/plugin-hcp-consul

Configuration

Add configuration to your app-config.yaml. For example:

consul:
  clientID: abcdefabcdefabcdefabcdefabcdef
  clientSecret: xyxy111xyxy111xyxy111xyxy111xyxy111xyxy111xyxy111
  organizationID: ff14c2a2-a937-4240-bf11-9d23ca01761d
  projectID: f3945084-71ac-495c-84b3-371100d27279

HCP overview page

The snippet below adds the plugin page to the /hcp-consul path . The page shows overall overview of the clusters.

// In packages/app/src/App.tsx

import { HcpConsulPluginPage } from '@hashicorp/plugin-hcp-consul';

const routes = (
  <FlatRoutes>
    ...
    <Route path="/hcp-consul" element={<HcpConsulPluginPage />} />
);

Requirements

• clientID, clientSecret and organizationID should be provided in the config file
• Default projectID can be provided in the config file. To override it, the projectID can be added as part of props of the component. <HcpConsulPluginPage projectID="f3945084-71ac-495c-84b3-371100d27279"/>

Service Instance Table Component

The snippet below adds a /hcp-consul-instances tab to the EntityPage that displays all service instances of the service

// In packages/app/src/components/catalog/EntityPage.tsx

import { EntityServiceInstancesTable, isHcpConsulServiceAvailable } from '@hashicorp/plugin-hcp-consul';

const serviceEntityPage = (
    ...
    <EntityLayout.Route
        if={isHcpConsulServiceAvailable}
        path="/hcp-consul-instaces"
        title="Instances"
    >
      <EntityServiceInstancesTable />
    </EntityLayout.Route>
)

Requirements

The component should have the necessary annotations:

• consul.io/cluster_resource_name annotation's value is the cluster resource name in HCP. It is required.
• consul.io/name annotation's value is the service name. It is required
• consul.io/namespace is the Namespace of the service. If omitted, it defaults to default
• consul.io/partition is the Partition of the service. If omitted, it defaults to default
