For GCE, this means creating a forwarding rule and a matching target pool, then adding the members to the target pool. :param name: Name of the new load balancer (required) :type name: ``str`` :param port: Port or range of ports the load balancer should listen on, defaults to all ports. Examples: '80', '5000-5999' :type port: ``str`` :param protocol: Load balancer protocol. Should be 'tcp' or 'udp', defaults to 'tcp'. :type protocol: ``str`` :param members: List of Members to attach to balancer. Can be Member objects or Node objects. Node objects are preferred for GCE, but Member objects are accepted to comply with the established libcloud API. Note that the 'port' attribute of the members is ignored. :type members: ``list`` of :class:`Member` or :class:`Node` :param algorithm: Load balancing algorithm. Ignored for GCE which uses a hashing-based algorithm. :type algorithm: :class:`Algorithm` or ``None`` :keyword ex_region: Optional region to create the load balancer in. Defaults to the default region of the GCE Node Driver. :type ex_region: C{GCERegion} or ``str`` :keyword ex_healthchecks: Optional list of healthcheck objects or names to add to the load balancer. :type ex_healthchecks: ``list`` of :class:`GCEHealthCheck` or ``list`` of ``str`` :keyword ex_address: Optional static address object to be assigned to the load balancer. :type ex_address: C{GCEAddress} :keyword ex_session_affinity: Optional algorithm to use for session affinity. This will modify the hashing algorithm such that a client will tend to stick to a particular Member. :type ex_session_affinity: ``str`` :return: LoadBalancer object :rtype: :class:`LoadBalancer` r r �namer z%s-tp)r � healthchecks�nodesZsession_affinity)r �protocolZ port_range�address) �hasattr�extrar r r r r Z ex_get_nodeZex_create_targetpoolZex_create_forwarding_rule� Exception�destroyr )r r! �portr$ � algorithm�membersr Zex_healthchecksZ ex_addressZex_session_affinityZ node_list�memberZtp_name� targetpool�forwarding_ruler r r �create_balancer[ s. 6 �� zGCELBDriver.create_balancerc C s, |j d �� }|r$|j d �� }|S |S dS )ar Destroy a load balancer.
