2way-ssl certs working from same machine only but not from other machine #1739

Closed hegdemahendra closed 2 years ago

hegdemahendra commented 2 years ago

Hello Team,

This may not be an issue and just a question - I am using https://github.com/vdesabou/kafka-docker-playground/blob/master/environment/2way-ssl to setup broker with ssl.

It works well when kafka client is in same machine (I am using Apach Nifi to produce/consume messages) But when I try to connect to broker from different machine in same network it is not working.

I added below DNS/IPs : [alt_names] DNS.1 = $i DNS.2 = localhost DNS.3 = ip-.ec2.internal IP.1 = {my server ip} IP.2 = 0.0.0.0

What could be the possible reason ?

I am using ip:port to access broker from another machine and not dns name.

Thanks Mahendra

Hey @hegdemahendra

This playground is made to be used 100% within Docker, so what you're trying to do is not supported. In my examples, whenever I have a Java producer for example, I set it up within a container. Sorry but I won't be able to help here
