How to change Slack title url

[drsheff]

Hi, everyone. I can't find value to change url link in title. I've got url like - http://vmalertmanager-vm-operator-victoria-metrics-k8s-stack-0:9093/#/alerts?receiver=slack-monitoring

How I can change that?

Hello, can you elaborate what url is this? Seems like it's generated by alertmanager.

I've encounted a similar issue, although it seems related more to the vmalert.

In the PagerDuty incidents that were created by the victoria-metrics-k8s-stack the last line points to the source of the alert, e.g.

Source: http://vmalert-vm-victoria-metrics-k8s-stack-5b6d6964b9-p84xt:8080/vmalert/alert?group_id=6238890889951999981&alert_id=13875164060741052938

In my case what helped is pointing vmalert to the correct external domain explicitly:

vmalert:
  spec:
    extraArgs:
      external.url: https://my-domain.com

I also had the spec.image.externalURL set for alertmanager itself, but this wasn't enough on its own. In this case though I think that setting just the above would fix the issue, effectively telling alertmanager what URL it's running under.
