Flink webui中不显示日志和输出

如题,我是通过docker-compose搭建的集群,用的是官方的docker-compose,改动了一下版本。

version: "2.1"
services:
  jobmanager:
    image: flink:1.9.2-scala_2.11
    expose:
      - "6123"
    ports:
      - "8081:8081"
    command: jobmanager
    environment:
      - JOB_MANAGER_RPC_ADDRESS=jobmanager

  taskmanager:
    image: flink:1.9.2-scala_2.11
    expose:
      - "6121"
      - "6122"
    depends_on:
      - jobmanager
    command: taskmanager
    links:
      - "jobmanager:jobmanager"
    environment:
      - JOB_MANAGER_RPC_ADDRESS=jobmanager

通过docker-compose启动,设置--scale taskmanager=3
测试通过了WordCount:

并且在shell中输入数据也没有报错(这里端口设置的是8888):

但是最后检查在所有的taskmanager中的log和stdout里面都没有输出:

求助是怎么回事呢?

容器部署的话日志是输出在console里的,所以webui看不到,可以通过docker logs -f [container] 或者docker-compose logs -f [SERVICE]的方式去查看。
