WEBHOOK_URL pointing to an cluster service svc.cluster.local fail

[zaggash]

Keel: 0.16.1
WEBHOOK_URL configured to reach an internal service: http://myservice.namespace.svc.cluster.local:5000

The logs reports failed to send the notification message with:

 Could not dial broker: dial tcp: lookup myservice.namespace.svc.cluster.local device or resource busy

However, if I set the same webhook service as a sidecar along with keel, and WEBHOOK_URL=http://127.0.0.1:5000, it works like a charm.

Could it be possible the issue below is related?

This is alpine issue.
I found workaround.
Add these to keel deployment:

command: ['/bin/sh', '-c', 'apk add bind-tools && /bin/keel']

env:
- name: GODEBUG
   value: netdns=go

dnsConfig:
  options:
  - name: ndots
    value: '2'

bind-tools: stackoverflow
