I have a running node server which listens on 3 different ports. I have three different subdomains of a url pointing to port 80 of the server on which node is running/listening.
What I am trying to do is proxy pass a request from a sub-domain to its respective port using haproxy.
My node server is dockerized with the ports exposed on the host. I can hit them individually using the server's IP address on their port so they seem to be running fine.
My haproxy will also be running inside a docker container. I am completely new to haproxy though I am fairly confident with dockers. I wrote my haproxy configuration via onine articles and blogs but as soon as I start my docker container using:
docker run --name my-running-haproxy \ -v ./haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg:ro \ haproxy:1.6.2 I get the following error:
Error response from daemon: ./haproxy.cfg includes invalid characters for a local volume name, only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed
So I tried debugging by removing configuration options until I had a very minimalistic config:
haproxy.cfg
global maxconn 256 debug defaults mode http timeout connect 5000ms timeout client 50000ms timeout server 50000ms frontend http-in bind *:80 default_backend default-server backend default-server server s0 127.0.0.1:3000 But still I am getting the same error.
Can anyone help me in this?
