support for proxy protocol (v2) ?

Open bcookatpcsd opened this issue 5 years ago • 6 comments

Does this support the proxy protcol (v2)?

If so, how do I use it?

I can't seem to find it if it does.

Can you tell what proxy protcol (v2) exactly is ?

https://docs.aws.amazon.com/elasticloadbalancing/latest/network/load-balancer-target-groups.html#proxy-protocol

in short it simply passes the connecting hosts ip information to the backend proxy..

so glider logs will show the client and not haproxy or whatever front end load balancer you might be using..

Is there any reason to use haproxy but not glider's built in scheduling algorithm?

With the proxy protocol, the glider would pass the client ip to the next server or if glider is the next host.

If glider(exit) is on 10.0.0.1 and client is 20.0.0.1 gliders log would show 20.0.0.1

If something is in front of glider, say haproxy or another glider instance.. haproxy or glider ( front ) is 30.0.0.1 and passes to glider (exit)

Client 20.0.0.1 would hit 30.0.0.1 and pass to exit. Exit would show client 20.0.0.1 even though it passed through 30.0.0.1 and then 10.0.0.1

The proxy protocol passes the client to servers that understand it.

If you can't explain it simply, you don't understand it well enough.

Thanks for your explanation, I know what the proxy protocol did, but I always use glider without haproxy in the front, glider has built in load balancing features, why do we need haproxy here?
