Goreplay

Golang 1.7 has a DNS problem of resolving hosts like **.local. This is important in kubernetes. So a fix is raised and released in Golang 1.7.1.

When testing goreplay, you should not port forward the source pod. For example,

--input-raw k8s://pod/fastapi-strawberry-example-64cdf67bf-nlcxj:8123

if you do k forward-port fastapi-strawberry-example-64cdf67bf-nlcxj 8123:8123, then goreplay will not receive traffic from this pod.
