// qingcloud loadBalancer and instance have a default strict Security Group(firewall),
// its only allow SSH and PING. So, first of all, you shoud manually add correct rules
// for all nodes and loadBalancers. You can simply add a rule by pass all tcp port traffic.
// The loadBalancers also need at least one EIP before create it, please allocate some EIPs,
// and set them in service annotation ServiceAnnotationLoadBalancerEipIds.
