flink- Could not acquire the minimum required resources

问题 Could not acquire the minimum required resources

taskmanager.numberOfTaskSlots

首先修改 taskmanager.numberOfTaskSlots: 4 属性，将其调大，结果还是没用

Available Task Slots都显示始终是0

查看flink-taskmanager 日志

发现并不能和 flink-jobmanager 进行通信

flink-taskmanager与flink-jobmanager 是通过 jobmanager.rpc.address: flink-jobmanager 指定的地址通信的

查看 k8s ,发现少了 jobmanager-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: flink-jobmanager
spec:
  type: ClusterIP
  ports:
  - name: rpc
    port: 6123
  - name: blob-server
    port: 6124
  - name: webui
    port: 8081
  selector:
    app: flink
    component: jobmanager

重启 flink, 解决

太坑了！！
