HAProxy OSS v1.8 does not include add/remove commands in Runtime API, but you can achieve similar functionality by using ready/disabled state commands.
- Add server(s) config in haproxy.cfg in
disabledstate:server-template websrv 1-100 192.168.122.1:8080 check disabled//This adds 100 servers (websrv1...websrv100) in disabled state
- Enable server (similar to
addfeature):set server be_template/websrv1 state ready
- Disable server (similar to
removefeature):set server be_template/websrv1 state maint
Address and port can be changed using Runtime API as usual: set server be_template/websrv1 addr 192.168.50.112 port 8000

One of the solution to use consul, the cost - reload service after some change.

If you use their ALOHA Load Balancer, there is an API to do this actions here :
