How to secure the kafka-pixy? #160

Closed amitgurav04 closed 5 years ago

amitgurav04 commented 5 years ago

How can I enable the HTTPS/SSL in kafka-pixy so that the request/response between client and kafka-pixy become secure.

Please suggest if any configurations are available to do the same.

Thanks in advance.

There is no way to do that. We never needed that. But, it should be relatively easy to implement. A gRPC listener should be started with TLS config. And then client would be able to use secure channel. If you want you can suggest a PR.

This is how to start a TLS enabled gRPC server

Thanks for giving the way to do this . I will implement this.

hey there, i'm very interested in working on this capability. i sketched out a little proposal, would you let me know what you think generally so we can agree on how best to structure things?

i'd propose:

small section in config, grpc, that contains paths to server certificates
add this to the config.go code
add method in config.go capable of producting grpc.ServerOpt struct (either insecure, the default, or TLS if detected in config)
use this method when creating gRPC server throughout the code

what are your thoughts? if it looks good i'll start implementing it like that.

Thank you @maxthomas, your proposal seems reasonable. I would suggested to call the section tls though. And if you could make sure that both gRPC and HTTP servers use TLS if configured that would be great.

thanks @horkhe ! i'll start working on this and push up an MR when it's ready for your review!
