Hi, Jiangang Glad to hear that you are looking to run Flink on Kubernetes.
It just because you are using the new Kubernetes version.The extensions/v1beta1 has been removed since v1.16. Please use apps/v1 instead. The apps/v1 is introduced from v1.9.0. I will create a ticket fix the documentation. Before release-1.10, you could use standalone per-job or standalone session cluster on K8s. There are some existing K8s operators to manage the application lifecycle(e.g. google flink-on-k8s-operator, lyft flink-k8s-operator). Running Flink native on K8s is supported from 1.10. You could find it here . It aims at to make Flink users more convenient to deploy Flink workloads on K8s cluster. However, we only support session cluster now. The per-job mode is in development.  https://github.com/apache/flink/blob/release-1.9/flink-container/kubernetes/README.md#deploy-flink-job-cluster  https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/kubernetes.html#flink-session-cluster-on-kubernetes http://shzhangji.com/blog/2019/08/24/deploy-flink-job-cluster-on-kubernetes/  https://github.com/GoogleCloudPlatform/flink-on-k8s-operator  https://github.com/lyft/flinkk8soperator  https://ci.apache.org/projects/flink/flink-docs-master/ops/deployment/native_kubernetes.html Best, Yang 刘建刚 <liujiangangp...@gmail.com> 于2020年1月13日周一 下午12:14写道： > I fail to deploy flink on k8s referring to > https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/kubernetes.html > When I run the command 'kubectl create -f jobmanager-deployment.yaml', > following error is reported: > [image: image.png] > I am new to k8s.
