Configuration Reference

This plugin is not compatible with DB-less mode.

Enable the plugin on a service

For example, configure this plugin on a service by making the following request:

curl -X POST http://{HOST}:8001/services/{SERVICE}/plugins \
    --data "name=upstream-auth-basic"  \
    --data "config.username=kingkong" \
    --data "config.password=1-big-ape"

SERVICE is the id or name of the service that this plugin configuration will target.

First, create a KongPlugin resource:

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: <upstream-auth-basic-example>
config: 
  username: kingkong
  password: 1-big-ape
plugin: upstream-auth-basic

Next, apply the KongPlugin resource to a Service by annotating the Service as follows:

apiVersion: v1
kind: Service
metadata:
  name: {SERVICE}
  labels:
    app: {SERVICE}
  annotations:
    konghq.com/plugins: <upstream-auth-basic-example>
spec:
  ports:
  - port: 80
    targetPort: 80
    protocol: TCP
    name: {SERVICE}
  selector:
    app: {SERVICE}

{SERVICE} is the id or name of the service that this plugin configuration will target.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

For example, configure this plugin on a service by adding this section to your declarative configuration file:

plugins:
- name: upstream-auth-basic
  service: {SERVICE}
  config: 
    username: kingkong
    password: 1-big-ape

SERVICE is the id or name of the service that this plugin configuration will target.

Enable the plugin on a route

For example, configure this plugin on a route with:

$ curl -X POST http://{HOST}:8001/routes/{ROUTE}/plugins \
    --data "name=upstream-auth-basic"  \
    --data "config.username=kingkong" \
    --data "config.password=1-big-ape"

ROUTE is the id or name of the route that this plugin configuration will target.

First, create a KongPlugin resource:

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: <upstream-auth-basic-example>
config: 
  username: kingkong
  password: 1-big-ape
plugin: upstream-auth-basic

Then, apply it to an ingress (Route or Routes) by annotating the ingress as follows:

apiVersion: networking/v1beta1
kind: Ingress
metadata:
  name: {ROUTE}
  annotations:
    kubernetes.io/ingress.class: kong
    konghq.com/plugins: <upstream-auth-basic-example>
spec:
  rules:
  - host: examplehostname.com
    http:
      paths:
      - path: /bar
        backend:
          serviceName: echo
          servicePort: 80

ROUTE is the id or name of the route that this plugin configuration will target.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

For example, configure this plugin on a route by adding this section to your declarative configuration file:

plugins:
- name: upstream-auth-basic
  route: <route>
  config: 
    username: kingkong
    password: 1-big-ape

ROUTE is the id or name of the route that this plugin configuration will target.

Enable the plugin globally

A plugin which is not associated to any service, route, or consumer is considered global, and will be run on every request. Read the Plugin Reference and the Plugin Precedence sections for more information.

For example, configure this plugin globally with:

$ curl -X POST http://{HOST}:8001/plugins/ \
    --data "name=upstream-auth-basic"  \
    --data "config.username=kingkong" \
    --data "config.password=1-big-ape"

Create a KongClusterPlugin resource and label it as global:

apiVersion: configuration.konghq.com/v1
kind: KongClusterPlugin
metadata:
  name: <global-upstream-auth-basic>
  annotations:
    kubernetes.io/ingress.class: kong
  labels:
    global: \"true\"
config: 
  username: kingkong
  password: 1-big-ape
plugin: upstream-auth-basic

For example, configure this plugin using the plugins: entry in the declarative configuration file:

plugins:
- name: upstream-auth-basic
  config: 
    username: kingkong
    password: 1-big-ape
