What? Please rephrase

I would like to include email configuration step in docker file

Please elaborate, what do you mean by email configuration?
What are you trying to achieve?

We have POD , if that POD is down we want to send email. so how we can configure email notification with in that POD. ?

A. That does not have anything to do with the dockerfile, rather with your deployment
B. Docker does not have pods, Podman and Kubernetes do. It would be better to ask in the forum relevant to the tool you’re using

As for docker, there’s no such native configuration, but there should be plenty of services that do that, like uptime kuma
