Hi, I'm trying to reproduce this Nginx configuration with HAProxy: https://memz.co/reverse-proxy-nginx-docker-microservices/
Where it's possible to use DNS as dynamic list to proxy to the right server. Our use case isn't container-related, but simply to move easily a customer from a backend server to another one, without to change the HAproxy configuration. The closest feature in HAProxy seems to be option http_proxy, however, no DNS lookup is performed: http://cbonte.github.io/haproxy-dconv/configuration-1.7.html#4.2-option%20http_proxy I have tried to use a resolver in haproxy configuration + in backend section: server XXXXXX %[hdr(host)]:8888 resolvers dns check inter 1000 init-addr last,libc,127.0.0.1 However, it doesn't work. Maybe with a lua script it's possible to implement that, but I would prefer to have a simple configuration like with Nginx. Do I missed something ? BTW, thanks for HAProxy, I like a lot this product ;-) Regards. -- Ludovic Gasc (GMLudo)
