Join load balancers

You can easily join a local load balancer using the following syntax:

config.vm.provider :softlayer do |sl|
  ...
  sl.join_load_balancer :vip => "1.1.1.1", :port => 443 do |service|
    service.destination_port = 443
    service.weight = 2
  end
end

The join_load_balancer directive takes some arguments and a block. Arguments are for service group configuration, instead the block is for service configuration.

NOTE:

You can't join load balancers from private-only machines.

Available service group parameters are:

Parameter	Description	Possible Values	Default
:method	Routing method	Routing methods	Round Robin
:port	Virtual port	Any port number
:type	Routing type	Routing types	TCP
:vip	Virtual IP address	Any IP address

Available service parameters are:

Parameter	Description	Possible Values	Default
:destination_port	TCP port on the node	Any port number
:health_check	Service health check	Health checks	Ping
:weight	Service weight	0-100	1

The directive can be specified multiple times for joining the machine to multiple load balancers/service groups.

Allocation of connections

Currently allocations are equally balanced between service groups. Service groups are created on the fly when necessary, and removed when empty.
