Kong rate limit plugin to multiple services

Question

I'm using rate limiting plugin by Kong, I'm using the declarative mode with a config file like:

_format_version: "3.0"
_transform: true

services:
- name: service1
  url: https://example.com/api/endpoint1
  routes:
  - name: route1
    paths:
    - /path1
- name: service2
  url: https://example.com/api/endpoint2
  routes:
  - name: route2
    paths:
    - /path2

plugins:
- name: rate-limiting
  service: service1
  config:
    second: 5
    policy: local
    limit_by: service
- name: rate-limiting
  service: service2
  config:
    second: 5
    policy: local
    limit_by: service

for the rate limiting plugin I'm also using the attribute limit_by: service, because I want to rate limit all the requests arriving for that service not just by grouping by IP.

I have more or less 12 endpoints like the above conf. and for every endpoint I want to apply, up to now, the same rate limit, every time there is the need to add a block like that:

- name: rate-limiting
  service: serviceN
  config:
    second: 5
    policy: local
    limit_by: service

is it possible to specify a rate-limit for every service globally but still groupyng by the service name?

In the docs is written:

so it seems that every time we need to add the limit_by property otherwise it should group requests by IP.

Is there any way to do it without repeating every tie the plugin block?

Thanks

You can use the following to configure the plugin globally:

plugins:
- name: rate-limiting
  config:
    second: 5
    policy: local
    limit_by: service

The parameter limit_by configured to the value service defines the scope of the rate limit buckets by service id. There is no need to explicitly specify service names or ids.
