haproxy_check.py does not validate SSL config correctly #12591
Description
problem
When using LB in SSL mode, CloudStack adds the following to the HAProxy config:
bind x.x.x.x:443 ssl crt /etc/cloudstack/ssl/x_x_x_x-443.pem alpn h2,http/1.1 ssl-min-ver TLSv1.2 no-tls-tickets ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-GCM-SHA256 ciphersuites TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256
Which is a valid HAProxy configuration, but the health check for the VR is failing at haproxy_check.py advanced check, because of this:
Maybe it is better to ignore all options after IP:PORT and rely on the haproxy config validation output?
/usr/sbin/haproxy -c -f /etc/haproxy/haproxy.cfg
