Upstream HTTP Basic Authentication

Kong Plugin to add HTTP Basic Authentication to the upstream request header.

Terminology

• plugin: a plugin executing actions inside Kong before or after a request has been proxied to the upstream API.
• Service: the Kong entity representing an external upstream API or microservice.
• Route: the Kong entity representing a way to map downstream requests to upstream services.
• upstream service: this refers to your own API/service sitting behind Kong, to which client requests are forwarded.
• API: a legacy entity used to represent your upstream services. Deprecated in favor of Services since CE 0.13.0 and EE 0.32.

Configuration

Enabling the plugin on a Service

With a database

Configure this plugin on a Service by making the following request:

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

Without a database

Configure this plugin on a Service by adding this section do your declarative configuration file:

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

In both cases, {service} is the id or name of the Service that this plugin configuration will target.

Enabling the plugin on a Route

With a database

Configure this plugin on a Route with:

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

Without a database

Configure this plugin on a Route by adding this section do your declarative configuration file:

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

In both cases, {route} is the id or name of the Route that this plugin configuration will target.

Enabling the plugin on an API

If you are using an older version of Kong with the legacy API entity (deprecated in favor of Services since CE 0.13.0 and EE 0.32.), you can configure this plugin on top of such an API by making the following request:

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

• api: either id or name of the API that this plugin configuration will target.

Global plugins

• Using a database, all plugins can be configured using the http://kong:8001/plugins/ endpoint.
• Without a database, all plugins can be configured via the plugins: entry on the declarative configuration file.

A plugin which is not associated to any Service, Route or Consumer (or API, if you are using an older version of Kong) is considered "global", and will be run on every request. Read the Plugin Reference and the Plugin Precedence sections for more information.
