Is it possible to assign TCP (no HTTP) connections to a backend based on an
alias haproxy has?
For example:
HAProxy has 3 alias names, server01.example.com, server02.example.com and
server03.example.com.
The haproxy.conf file defines a front end and 3 back ends:
frontend static-svc
bind *:80
mode tcp
option tcplog
default_backend svc-svc-default
backend stactic-svc01
balance source
option tcplog
server server01 127.0.0.1 check
backend static-svc02
balance source
option tcplog
server server02 127.0.0.2 check
backend static-svc03
balance source
option tcplog
server server03 127.0.0.3 check
The idea being that each static-service should only service in coming
requests thru a specific alias; therefore, requests coming from the
internet looking for server01.example.com would be sent to the static-svc01
back end. I have seen tons of examples on how to do this with HTTP, but I
can't find any that focus on pure TCP. My application does not use HTTP at
all.
Thanks.
Hmmm in case of ssl you could do something like this using the sni
extension:
tcp-request inspect-delay 5s
tcp-request content accept if { req_ssl_hello_type 1 }
use_backend sratic-svc01 if { req.ssl_sni -i server01.example.com }
otherwise not sure how can you access the host header in the tcp stream.
