Documentation on router sharding

Issue

• In the release notes we read about router sharding, this is feature that we would like to use. However I cannot find any reference about router sharding in the documentation nor in the knowledge base.

Using router sharding, you can specify a selection criteria for either namespaces (projects) or labels on routes. This enables you to select the routes a router would expose, and you can use this functionality to distribute routes across a set of routers, or shards.

https://docs.openshift.com/enterprise/3.2/release_notes/ose_3_2_release_notes.html

Could you please point us to (or provide us with) information on how to implement this feature?

• As it is not specifically mentioned in the documentation I want to verify that the following assumption is correct:

If we use two router shards (first with selector 'env=development' and the other with 'env=production') two router shards will be created. Is it correct to assume that on the 'env=development' shards only routes will be know that have the 'env=development' label? So we can use these router shards to "secure" our production routes (no production routes will be known by the development router shards)?
