java - 使用远程调试运行 docker-compose。英特尔，Java 11

问题描述

我将指南中的步骤应用于我的项目（https://www.jetbrains.com/help/idea/run-and-debug-a-spring-boot-application-using-docker-compose.html）。总而言之，我将此行添加到 Dockerfile-Djava.security.egd=file:/dev/./urandom并将命令添加到 docker-compose command: java -Djava.security.egd=file:/dev/./urandom -jar /usr/app/test-app.jar。在 docker-compose 中点击命令附近的调试按钮后，远程配置为：

Debugger mode: Attach to remote JVM
Transport: Socket
Host: localhost
Port: 5005
Command line arguments for remote JVM: -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005;

Docker Compose 运行配置（启动前）选项：

--------------------------------------------------
Port               | Local port | Container port |
-------------------------------------------------|
Java Debugger port | 5005       | 5005           |
--------------------------------------------------

Custom command: java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005 -Djava.security.egd=file:/dev/./urandom -jar /usr/app/test-app.jar
Custom options: -p 5005:5005

运行我收到异常的配置： Error running 'Remote JVM Debug with compose': Unable to open debugger port (localhost:5005): java.net.ConnectException "Connection refused: connect"

我试图通过将地址更改为来解决这个问题*:<port>。生成的自定义命令是 java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=*:5005 -Djava.security.egd=file:/dev/./urandom -jar /usr/app/test-app.jar. 然后我得到异常： Error running 'Remote JVM Debug with compose': Unable to open debugger port (localhost:5005): java.io.IOException "handshake failed - connection prematurally closed"。我也尝试将端口更改为8080，但结果是一样的。如何解决此问题并使用 docker-compose 进行远程配置（启动前）？演示问题的项目：https ://github.com/leonaugust/intelij_docker_problem

Dockerfile

码头工人-compose.yml

version: '3.1'
services:

  test-app:
    build: .
    container_name: test-app
    image: test-app

    ports:
      - 8080:8080
    command: java -Djava.security.egd=file:/dev/./urandom -jar /usr/app/test-app.jar

解决方案

Dockerfile试一试：

ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar","/usr/app/test-app.jar"]
