it worked, there seems to be some parameters in our haproxy.cfg which is
upsetting this extension. On using default haproxy.cfg.template, it worked!
:-)
Can someone confirm, if following understanding that ports from port
mapping section of autoscaled cartridge are used by haproxy extension in
the following fashion -
"portMapping":[
{
"protocol":"http", // protocol
"port":"80", // port on autoscaled cartridge
"proxyPort":"8280" // port on haproxy / loadbalancer
cartridge
}
]
Thank you for all your quick support
Parvez
