Reverse Proxy Documentation Update

[rphlwnk]

Hi there,

i just launched step-ca at our systems and everything is working as expected!

As i was setting up a reverse proxy (based on Production considerations ) for step-ca I was not able to get the originating client IP in the step-ca log. I also did not find anything in the documentation.

I then found #2002 where the Environment Variable STEP_LOGGER_LOG_REAL_IP is mentioned here

certificates/logging/handler_test.go

Line 148 in 47c08d5

// proxy IP when STEP_LOGGER_LOG_REAL_IP is set to true and specific headers are

as soon as I did set this in the step-ca.services I was able to get the client IP instead of the reverse proxy / 127.0.0.1 IP.

Maybe this could be added to the documentation somewhere.
