What happened?
I want to set up channel alerts in RocketChat. But it seems technically impossible at the moment.
What you expected to happen?
My config:
apiVersion: monitoring.coreos.com/v1alpha1
kind: AlertmanagerConfig
spec:
...
receivers:
- name: "rocketchat-warnings"
rocketchatConfigs:
- tokenID:
name: rocketchat-token
key: MyChannel-Alerts-tokenid
token:
name: rocketchat-token
key: MyChannel-Alerts-token
channel: "#MyChannel-Alerts"
apiURL: "https://rocketchat.mysite.com"
title: "🔥 Alert from Alertmanager"
text: test
Output file (cat /etc/alertmanager/config_out/alertmanager.env.yaml):
...
- name: monitoring/alermanagerconfig/rocketchat-warnings
rocketchat_configs:
- token_id: superSecretTokenID
token: superSecretToken
short_fields: false
link_names: false
...
How to reproduce it?
No response

No response
