Plugin with same ID but different attached entities causes failure in postprocess after syncing to Kong gateway #272
Description
When we sync Kong configuration with a plugin having the same ID but different attached entities (combination of service, route, consumer, consumer group) with an existing plugin, the plugin is updated successfully but error happens on post process like:
Error: 1 errors occurred:
while post processing event: inserting plugin response-transformer for service a872ace2-7d61-4c74-abec-092b308cbff4: entity already exists
The minimal reproduce scenario:
Run a Kong gateway with DB backed and then run deck sync with the following config file:
_format_version: "3.0"
services:
- name: service-1
host: "example.com"
- name: service-2
host: "konghq.com"
plugins:
- name: "response-transformer"
config:
add:
headers:
- 'X-Test-Header: added'
id: 3a3e4bea-ef66-42c2-a528-68b6cfab0ef1
service: service-1 # change to service-2 and run `deck sync` again will trigger the issue.
