Avi Vantage Platform Load Balancer Provider
========
#### About Avi Vantage Platform
The Avi Vantage Platform is built on software-defined architectural principles to create a centrally managed pool of distributed load balancers to deliver application services close to the applications.
#### About this provider
This provider load balances Rancher services using Avi Vantage Platform Load Balancer. It uses REST API to update the Avi controller which enables the Avi Service Engines to load balance the Rancher Services.
#### Usage
1. Deploy the stack for this provider from Rancher Community Catalog.
While deploying, you need to give the username, password (optional,
read below), Avi Controller IP address, Avi Controller Port, the
Cloud name where Virtual Services and Pools are created.
2. Create Virtual Services using Avi Controller console. Make sure you
create VS in given cloud in Avi. Leave the Virtual Service pool as
empty. Configure any policies or rules for Virtual Service.
3. Create services in Rancher with public host port mapping and adding
label `io.rancher.service.external_lb.endpoint` with value as Virtual
Service name created in previous step. You can scale out/in the
service or stop the service and the changes will get reflected on Avi
Controller and Service Engine.
Environment Variables
========
| Variable Name | Description | Default Value | Optional |
|--------------------------|-----------------------------------------------------------------------------------------------|--------------------|-----------------------------------|
| AVI_USER | User name to log into Avi Controller | | No |
| AVI_PASSWORD | Password for Avi user. This is optional if you are using Rancher Secrets to provide password. | | Yes (if using Rancher Secrets) |

Using Rancher Secrets for Avi Password
----
Optionally, you can use the Rancher Secrets to pass the Avi controller
password instead of using environment variable.
1. Run the Rancher Secrets service before deploying this provider stack.
2. Create a secret named "avi-creds".
3. While deploying the Avi provider stack, use the "avi-creds" secret
for Avi Provider service.
