Kong Service Manager Plugin

The Kong Service Manager plugin offers the facility to manipulate your service from different Kong environments, in your component, detailing information about the service, listing the routes it has and also offering the possibility of manipulating plugins without leaving the backstage.

Installation 🔧

If you are using yarn 3.x:

yarn workspace app add @veecode-platform/plugin-kong-service-manager

If you are using other versions:

yarn add --cwd packages/app @veecode-platform/plugin-kong-service-manager

Configuration ⚙️

1- Proxy

In the app-config.yaml file, add the proxy configuration:

proxy:
  endpoints:

   "/kong-manager/api":
        target: https://api.manager.apr.vee.codes/default
        allowedHeaders: ['Authorization', 'Content-Type']
        headers: 
          Accept: application/json
          Content-Type: 'application/json'

    "/kong-other-manager/api":          <<-- If you have more than one instance of Kong, we need to list it too, as long as the proxy endpoint is different
      target: https://api.manager.apr.vee.codes/default
      allowedHeaders: ['Authorization', 'Content-Type']
      headers: 
        Accept: application/json
        Content-Type: 'application/json'

2- Annotations

The Plugin recognizes 2 annotations for its operation, the first being kong-manager/service-name, which will identify the service that will be used as a parameter. In this annotation you can enter the name of the service or its id, preferably the name. It's also worth noting that each catalog-info.yaml can only receive one service. The other annotation will be kong-manager/instance, which will receive the instances in which the kong will make the calls, this one can receive more than one item, properly separated by commas and without spaces. It's important to note that the instances must be configured as endpoints in the app-config.yaml, as per the previous section, if they haven't been properly configured the calls won't be answered.

Here's an example:

apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
  name: "Component A"
  description: "An example"
  annotations:
    github.com/project-slug: test/ComponentA
    backstage.io/techdocs-ref: dir:.
+    kong-manager/service-name: nameservice_test_A01
+    kong-manager/instance: /kong-manager/test,/kong-manager/test1
   
spec:
  type: service
  lifecycle: prod
  owner: "devops"

UI 💻

Taking into account that the settings are ok, we now need to adjust our EntityPage.tsx to render the plugin correctly. To do this, we'll change the following file packages > app > src > components > catalog > EntityPage.tsx:

... 
+ import { KongServiceManagerPage, isKongServiceManagerAvailable } from '@veecode-platform/plugin-kong-service-manager';

...

const serviceEntityPage = (
  <EntityLayout>
    <EntityLayout.Route path="/" title="Overview">
      {overviewContent}
    </EntityLayout.Route>

    <EntityLayout.Route path="/ci-cd" title="CI/CD">
      {cicdContent}
    </EntityLayout.Route>

+    <EntityLayout.Route
+      if={isKongServiceManagerAvailable}
+      path="/kong-service-manager" title="Kong">
+      <KongServiceManagerPage/>
+    </EntityLayout.Route>

  </EntityLayout>
);

...

ℹ️ We've used the ServiceEntityPage component for the example, but it can be replicated for any of the existing types in the EntityPage.

Now that the plugin is properly configured, let's take a look at the screens it offers:

👉 About Page:

Here we've highlighted all the information about the service referenced in the component, note that in the top right corner we have a combobox where we can navigate between the available kong instances:

👉 All Routes:

On this screen, we list all the routes that the service has:

Also noteworthy is the behavior of the tags field, which expands when triggered:

👉 All Plugins:

Finally, we have the list of plugins:

• List of all plugins eligible for your Kong instance; ✅
• Installing / Removing and Editing a plugin at your Service; ✅
• Plugin search field; ✅
• Filtering by the plugins installed in the service; ✅

Listing of all plugins:

Installing a plugin

For the example, we'll use the rate limiting plugin:

When you install it, it will appear on the Associated Plugins tab:

From then on, the plugin will already be configured in your service:
