HAProxy

Be careful to always indent HAProxy configuration with tabs!

Example (frontend/backend) configuration (here cookies are just for tests purpose):

frontend f.8082
        bind :8082
        default_backend b.8082

backend b.8082
        balance roundrobin
        http-response   set-header      X-Server        %s
        http-response   set-header      Set-Cookie      server=%s
        server kube-1   10.0.3.101:8082 check
        server kube-2   10.0.0.187:8082 check
        server kube-3   10.0.0.204:8082 check

Edit and apply configuration:

sudo nano /etc/haproxy/haproxy.cfg
sudo service haproxy restart
