Rancher show alerting but email is not received?

I am using Rancher for Kubernetes deployment. I have setup alerts if pod are downs. If a pod is down then it shows alerting but email is never received. Kindly let me know what is the issue?

I have opened an issue on GitHub for same. https://github.com/rancher/rancher/issues/20492

Solution

  • As per attached issue on github

    Hello, I have resolved this issue. I have checked log for alertmanager AlertManager is found in CluserName ->System (DropDown) & there is AlertManager Pod.

    My issue was i have added the Non TLS enabled SMTP credentials though rancher validated non TLS enabled credentials & sent Test email but looks like rancher required a TLS enabled SMTP Credentials.
