########## File path: docs/ops/deployment/kubernetes.md ########## @@ -166,18 +249,34 @@ kind: Service metadata: name: flink-jobmanager spec: + type: ClusterIP ports: - name: rpc port: 6123 - name: blob port: 6124 - - name: query - port: 6125 - name: ui port: 8081 selector: app: flink component: jobmanager {% endhighlight %} +`jobmanager-rest-service.yaml`. Optional service, which is used to add a `NodePort` on the jobmanager rest service so that user could submit job via `<public-node-ip>:<node-port>`. Review comment: My reasoning, that there maybe two types of readers of this docs: * people like devs, who have a test K8s cluster and want to setup test/experimental Flink cluster. For this, I assume they can run `kubectl port-forward|proxy` and also create resources by `kubectl`. For them the existing means should be already enough to make Flink JM available from a local dev machine. Showing them method that exposes `NodePort` would be like giving a poor example; * people like ops, that operate production K8s cluster. In that case they are probably knowledgeable enough how to expose a service properly. There are some blog posts in internet, for example [this one](https://medium.com/google-cloud/kubernetes-nodeport-vs-loadbalancer-vs-ingress-when-should-i-use-what-922f010849e0) that give some information what are the different ways and in which situations to make service available outside of K8s cluster. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
