Newline in Alert description

[Guna Kambalimath]

Hello,

I have my alert configuration written like the following:

- name: pod-status

    groups:

      - name: pod not in expected state

        rules:

          - alert: microservice_status_alert

            expr: kube_pod_container_status_running == 0

            for: 2m

            labels:

              severity: critical

            annotations:

              description: "microservice {{ $labels.container }} is not running.\nPod: {{ $labels.pod }}.\nInstance: {{ $labels.instance }}

Alert that I received on email looks like this:

Labels
alertname = microservice_restart_alert
cbacid = cbac1
Annotations
description = some microservice has restarted 3 times. Pod-name: some-5cb95695c-cpgvk. Instance: x.x.x.1:<port>

Question:

The new line "\n" given is not getting interpreted in mail received. I want description look like this:

description = some microservice has restarted 3 times 

Pod-name: some-5cb95695c-cpgvk.  

Instance: x.x.x.1:<port>

The above looks more neat. 

Please help with the same.

Thanks,

Guna

Is it a HTML mail?  Have you tried inspecting the HTML?  A newline in HTML doesn't render as a line break, except with certain CSS styles.
