Connector resource

A connector binds a local workload to listeners in remote sites. Listeners and connectors are matched by routing key.

On Kubernetes, a Connector resource has a selector and port for specifying workload pods.

On Docker, Podman, and Linux, a Connector resource has a host and port for specifying a local server. Optionally, Kubernetes can also use a host and port.

Examples

A connector in site East for the Hello World backend service:

apiVersion: skupper.io/v2alpha1
kind: Connector
metadata:
  name: backend
  namespace: hello-world-east
spec:
  routingKey: backend
  selector: app=backend
  port: 8080
