Fronting mailpit with AWS NLB running in k8s

[pureiboi]

Hi,

Wonder if anyone had a similar setup using MailPit?

Currently, I'm running MailPit service in AWS EKS

the flow
client -> nlb -> eks pod

Strange enough the mailpit works if i do port-forward, while it is not working when traffic starts from nlb

Edit:

Looks like I'm missing out on some critical information on the setup.

This perfectly working

client -> nlb -> MailPit (eks pod)

After further investigation of the setup I have. Looks like it's an issue with Linkerd unable to forward the request to the downstream service.

While it's not issue due to MailPit, I'm still curious if anyone actually set it up this way.

Finally figured out that linkerd proxy is blocking the traffic becos of the protocol detection,
