==========
|
||
Rancher service facilitating integration of rancher with F5 BIG-IP - external load balancer. This service updates F5 with services created in Rancher that ask to be load balanced using F5.
|
||
Initial version comes with support for an unpartitioned F5 BIG-IP installation
|
||
|
||
Design
|
||
==========
|
||
* The F5 service gets deployed as a Rancher service containerized app.
|
||
|
||
* It enables any other service to be registered to external F5 if the service has exposed a public port and has the label 'io.rancher.service.external_lb_endpoint'
|
||
|
||
* Value of this label should be equal to the VirtualServer Name on F5 BIG-IP
|
||
|
||
* The VirtualServer should be pre-configured on F5
|
||
|
||
* The rancher hosts on which the containers of the service are running, will be added to the F5 setup as nodes
|
||
|
||
* A new F5 pool will be created for the service, having the Rancher host_ip:port as pool members
|
||
|
||
* This F5 pool created will have a name of the pattern of"service.Name"_"environment_uuid"_"rancher.internal" - The suffix "rancher.internal" is configurable while launching the catalog template.
|
||
|
||
* This pool will be assigned to the F5 virtual server provided to Rancher via the above label
|
||
|
||
* After the F5 configuration is complete, the service on Rancher can be reached using the F5 vip:port
|
||
|
||
* Rancher’s F5 service will keep on synching new services to F5 and remove/scale up-scale down as changes are made on Rancher.
