Custom webhook url has always the same port

[exArax]

Hi,

I am declaring a custom webhook url at the alertmanager-config.yaml and no matter what port I am declaring it always changes back to 3000. Do you have any what causes this ?

kind: ConfigMap
apiVersion: v1
metadata:
name: alertmanager-config
namespace: monitoring
data:
config.yml: |-
global:
route:
receiver: custom_webhook
group_by: ['alertname', 'priority']
group_wait: 10s
repeat_interval: 1m
routes:
- receiver: custom_webhook
match:
severity: deployed
group_wait: 10s
repeat_interval: 1m
receivers:
- name: custom_webhook
webhook_configs:
- url: 'http://0.0.0.0:4000/webhook'

This yaml is dynamically generated on make so your changes will be overridden. This config is generated by the ksonnet libs in prometheus-operator so you might need to override in your own config.
