Deploy a QoS ruled load balancer
--------------------------------
This solution limits the bandwidth available through the Load Balancer's VIP by
applying a Neutron Quality of Service(QoS) policy to the VIP, so Load Balancer
can accept the QoS Policy from Neutron; Then limits the vip of Load Balancer
incoming or outgoing traffic.
.. note::
Before using this feature, please make sure the Neutron QoS externsion(qos)
is enabled on runing OpenStack environment by command
.. code-block:: console

**Scenario description**:
* QoS-policy created from Neutron with bandwidth-limit-rules by us.
* Back-end servers 192.0.2.10 and 192.0.2.11 on subnet *private-subnet* have
been configured with an HTTP application on TCP port 80.
* Subnet *public-subnet* is a shared external subnet created by the cloud
operator which is reachable from the internet.
* We want to configure a basic load balancer and want to limit the traffic
bandwidth when web traffic reaches the vip.
**Solution**:
1. Create QoS policy *qos-policy-bandwidth* with *bandwidth_limit* in Neutron.
2. Create load balancer *lb1* on subnet *public-subnet* with the id of
*qos-policy-bandwidth*.
3. Create listener *listener1*.
4. Create pool *pool1* as *listener1*'s default pool.
5. Add members 192.0.2.10 and 192.0.2.11 on *private-subnet* to *pool1*.
**CLI commands**:
::
openstack network qos policy create qos-policy-bandwidth
openstack network qos rule create --type bandwidth_limit --max-kbps 1024 --max-burst-kbits 1024 qos-policy-bandwidth
openstack loadbalancer create --name lb1 --vip-subnet-id public-subnet --vip-qos-policy-id qos-policy-bandwidth
# Re-run the following until lb1 shows ACTIVE and ONLINE statuses:
openstack loadbalancer show lb1
openstack loadbalancer listener create --name listener1 lb1 --protocol HTTP --protocol-port 80
openstack loadbalancer pool create --name pool1 --lb-algorithm ROUND_ROBIN --listener listener1 --protocol HTTP
openstack loadbalancer member create --subnet-id <private_subnet_id> --address 192.0.2.10 --protocol-port 80 pool1
openstack loadbalancer member create --subnet-id <private_subnet_id> --address 192.0.2.11 --protocol-port 80 pool1
Deploy a non-terminated HTTPS load balancer

A non-terminated HTTPS load balancer acts effectively like a generic TCP load
