How to set up SSL passthrough with multiple domains with HAproxy?
How does one set up HAproxy for multiple domains, to multiple backends while passing through SSL? I would also be open to an nginx solution
Example in diagram for a better explanation:
backend_domain_a domain-a.com-. .-> 18.104.22.168 | | +-> haproxy -+ | | backend_domain_b domain-b.com-' '-> 789.789.789.789
Note Each backend server will be issueing their own certificate. Hence the need for SSL passthrough.
I have this configuration, but doesn’t work for multiple reasons (the key one being the missing port number):
frontend www bind *:80 bind *:443 option tcplog acl host_domain_a hdr(host) -i domain-a.com acl host_domain_b hdr(host) -i domain-b.com use_backend backend_domain_a if host_domain_a use_backend backend_domain_b if host_domain_b backend backend_domain_a server web_a 22.214.171.124 check backend backend_domain_b server web_b 789.789.789.789 check
In others words, I want Haxproxy to not terminate the SSL.
I initially wanted to do this with
Nginx but apparently it can’t act as a non-terminating point while reading the host details (though might be available in future versions with ssl preread)
