为什么我的火花网页界面不活跃？

Question

我创建了一个docker compose-file，其中定义了Spark、Airflow、Postgres和Flower。在我的docker-compose up -d中执行cmd之后，我得到以下输出：

[+] Running 11/11

一切似乎都运行正常。所以，当我冲浪到localhost:5555时，我得到了UI of Flower，当我冲浪到localhost:8080时，我得到了Airflow的UI。但当我在localhost:4141上冲浪时，我会得到谷歌Chrome版的This page is not working。火花是怎么回事？

Spark服务是如何在我的docker-compose file中定义的

  #Spark 
  spark:
    image: docker.io/bitnami/spark:3
    environment:
      - SPARK_MODE=master
      - SPARK_RPC_AUTHENTICATION_ENABLED=no
      - SPARK_RPC_ENCRYPTION_ENABLED=no
      - SPARK_LOCAL_STORAGE_ENCRYPTION_ENABLED=no
      - SPARK_SSL_ENABLED=no
    ports:
      - '4141:4141'
    volumes:
      - ./spark-apps:/opt/spark-apps
  spark-worker:
    image: docker.io/bitnami/spark:3
    environment:
      - SPARK_MODE=worker
      - SPARK_MASTER_URL=spark://spark:7077
      - SPARK_WORKER_MEMORY=1G
      - SPARK_WORKER_CORES=1
      - SPARK_RPC_AUTHENTICATION_ENABLED=no
      - SPARK_RPC_ENCRYPTION_ENABLED=no
      - SPARK_LOCAL_STORAGE_ENCRYPTION_ENABLED=no
      - SPARK_SSL_ENABLED=no

星火图像在端口8080上公开web接口，因此要访问它，必须将端口8080映射到主机端口之一。例如：- 8888:8080在ports:部件下将web-ui映射到localhost:8888。
