 Tenant Image Types
-------------------
+==================
 
 For BIG-IP Next on rSeries, there is a single tenant image type that can be obtained from downloads.f5.com. On the downloads site, you will see a tar.bundle file which you can download and verify using one of the available signature files. In the example below the file **BIG-IP-NEXT-20.1.0-2.279.0+0.0.75.tar.bundle** is the image file that you will use to deploy BIG-IP Next tenants on rSeries appliances or VELOS chassis.

 Tenant creation via the API is as simple as defining the parameters below and sending the POST to the rSeries out-of-band IP address. The API call below will create a tenant; many of the fields are defined as variables in Postman. That way the API calls don't have to be rewritten for different tenant names or IP addressing, or images, and they can be reused easily and adapted to any environment. In the example below, the **running-state** will be set for **Configured** and then a subsequent API call will set it to **Deployed**, but this could all be done via a single API call. This is done to show how changes can be made to the tenant status after its created.

 rSeries tenants have static vCPU and memory allocations just like vCMP. These can be changed after a tenant has been deployed, but the tenant will have to be suspended (put in the **Provisioned** state), then the change to CPU and or memory allocation can be made. A tenant can be expanded assuming adequate resources are available. Once the changes are completed the tenant can be put into the **Deployed** state and returned to service.
