The user willing to make use of the Octavia service needs to send an email to superc@cineca.it asking for the tenant to be enabled to the service. Once the tenant is enabled to the service by the User Support Team, all users of the tenant will be able to use the service.
2. Create a Load Balancer.
| Code Block |
|---|
openstack loadbalancer create --name <loadbalancer_name> --vip-subnet-id <subnet_id> |
...
Note: Wait until the creation is completed. It will take a while and the next steps will return an error if the load balancer is not available.
3. Create a Listener.
| Code Block |
|---|
openstack loadbalancer listener create --name <listener_name> --protocol HTTP --protocol-port 80 <loadbalancer_name> |
4. Create a Pool.
| Code Block |
|---|
openstack loadbalancer pool create --name <pool_name> --lb-algorithm <algorithm_e.g.ROUND_ROBIN> --listener <listener_name> --protocol HTTP |
5. Add Members to the pools.
| Code Block |
|---|
openstack loadbalancer member create --subnet-id <subnet_id> --address <ip_vm_1> --protocol-port 80 <pool_name> openstack loadbalancer member create --subnet-id <subnet_id> --address <ip_vm_2> --protocol-port 80 <pool_name> |
...
You can find the <port_id> if you navigate to the description of your load balancer on the ADA Cloud Dashboard. Select the Network → Load Balancers section on the left-hand menu of the dashboard. Then, click on your load balancer and go to the Overview tab. You can also use the CLI to identify the value of the <port_id>.
7. Test your load balancer.
Finally, use this floating-IP to reach the nginx servers (see figure bellow). The traffic will be managed by the load balancer following the algorithm <algorithm_e.g.ROUND_ROBIN> (see Step 3).
