Kubernetes External Service

Kubernetes External Service

To make a local service in a Kubernetes cluster, which points to an address on a remote system, you can use the following yaml as example:

apiVersion: v1 kind: Service metadata: name: local-service namespace: my-namespace spec: externalName: remote-service.somewhere.com ports: - port: 8080 protocol: TCP targetPort: 80 sessionAffinity: None type: ExternalName
Code language: YAML (yaml)

This probably (will test this some time later) will also work if you want to move a service from “namespace-a” to “namespace-b”, and want to keep a reference inside “namespace-a” for other pods which depend on it:

apiVersion: v1 kind: Service metadata: name: the-service namespace: namespace-a spec: externalName: the-service.namespace-b ports: - port: 8080 protocol: TCP targetPort: 8080 sessionAffinity: None type: ExternalName
Code language: YAML (yaml)
