Attached connectors

• An attached connector is one not directly in the site namespace but in a peer namespace.
• Useful for sharing services across networks.
• Requires the router namespace and the workload namespace to opt in to the attachment.
• The router side controls the routing key. The workload side controls the selector.
• siteNamespace and connectorNamespace must correspond.
• AttachedConnector and AttachedConnectorBinding must have matching names.
• The connector side is responsible for selecting pods, while the binding side controls the routing key.
• If you want to expose a workload (say a database) in multiple networks, you need multiple AttachedConnectors, one for each corresponding binding that resides in a particular site belonging to a network.
• You can't create attached connectors with the CLI. You have to use YAML resources.

An attached connector is a connector in a peer namespace.
