我想部署一个服务，允许我在Jupiter笔记本中使用Spark和MongoDB。
我使用docker-compose来构建服务，如下所示：

version: "3.3"

volumes:
    shared-workspace: 
    networks:
    spark-net:
        driver: bridge

services:   
  spark-master:
    image: uqteaching/cloudcomputing:spark-master-v1
    container_name: spark-master
    networks:
        - "spark-net"
    ports:
        - "8080:8080"
        - "7077:7077"
    environment:
        - INIT_DAEMON_STEP=setup_spark
        - "PYSPARK_PYTHON=/usr/bin/python3"
        - "PYSPARK_DRIVER_PYTHON=/usr/bin/python3"

  spark-worker-1:
    image: uqteaching/cloudcomputing:spark-worker-v1
    container_name: spark-worker-1
    depends_on:
        - spark-master
    networks:
        - "spark-net"
    ports:
        - "8081:8081"
    environment:
        - "SPARK_MASTER=spark://spark-master:7077"
        - "PYSPARK_PYTHON=/usr/bin/python3"
        - "PYSPARK_DRIVER_PYTHON=/usr/bin/python3"

  spark-worker-2:
    image: uqteaching/cloudcomputing:spark-worker-v1
    container_name: spark-worker-2
    depends_on:
        - spark-master
    networks:
        - "spark-net"
    ports:
        - "8082:8082"
    environment:
        - "SPARK_MASTER=spark://spark-master:7077"
        - "PYSPARK_PYTHON=/usr/bin/python3"
        - "PYSPARK_DRIVER_PYTHON=/usr/bin/python3"

  mongo:
    image: mongo
    container_name: 'mongo'
    networks:
            - "spark-net"
    ports:
            - "27017:27017"

  mongo_admin:
    image: mongo-express
    container_name: 'mongoadmin'
    networks:
            - "spark-net"
    depends_on:
            - mongo
    links:
            - mongo
    ports:
            - "8091:8091"

  jupyter-notebook:
    container_name: jupyternb
    image: jupyter/all-spark-notebook:42f4c82a07ff
    depends_on:
        - mongo
        - spark-master
    links:
        - mongo
    expose:
        - "8888"
    networks:
        - "spark-net"
    ports:
        - "8888:8888"
    volumes:
        - ./nbs:/home/jovyan/work/nbs
        - ./events:/tmp/spark-events
    environment:
        - "PYSPARK_PYTHON=/usr/bin/python3"
        - "PYSPARK_DRIVER_PYTHON=/usr/bin/python3"
    command: "start-notebook.sh \
              --ip=0.0.0.0 \
              --allow-root \
              --no-browser \
              --notebook-dir=/home/jovyan/work/nbs \
              --NotebookApp.token='' \
              --NotebookApp.password=''
             "

结果是这样的：

我使用t know why. Even I set these 2服务来侦听不同的端口。 它们同时使用8081/tcp`，这导致它们都崩溃了。
我想解决这个问题。
