如何使用IntelliJ调试在Docker中运行的应用程序？ [英] How to debug an application running in Docker with IntelliJ?

问题描述

我有一个在码头上运行的Jetty应用程序。我想使用本地IntelliJ调试此应用程序。我使用的是14.1版，因此我已经安装了Docker Integration插件。

I have a Jetty application running in docker. I would like to debug this application using my local IntelliJ. I am on v 14.1, so I have installed the Docker Integration plugin.

在Clouds下，我使用的是单击 +时显示的默认值。 IntelliJ文档说这应该没问题。

Under Clouds, I am using the default values that showed up when I click on the '+'. IntelliJ docs say this should be OK. Here the

API URL: http://127.0.0.1:2376
Certificates folder: <empty>

我不确定它们的用途，所以我不知道这些值是否正确。

I'm not sure what these are used for, so I dont know if these values are right.

在运行/调试配置下，我正在使用Docker部署，其值如下：

Under Run/Debug configurations, I am using Docker Deployment, and the following values:

Deployment: Docker Image
Image ID: The docker image ID 
Container name: The name of the container

当我尝试运行它时，我得到
javax.ws.rs.ProcessingException：org.apache.http.conn.HttpHostConnectException：连接到http://127.0.0.1:2376 [/127.0.0.1]失败：连接被拒绝

When I try to run this, I get javax.ws.rs.ProcessingException: org.apache.http.conn.HttpHostConnectException: Connect to http://127.0.0.1:2376 [/127.0.0.1] failed: Connection refused

显然我使用的API URL值不正确。关于该值应该有什么建议？

Obviously the API URL value I am using is incorrect. Any suggestions on what that value should be?

我的调试选项是：

 -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=n -Djava.compiler=NONE

推荐答案

Sheesh没关系。我真的不需要Docker集成插件。似乎更多地是直接通过Intellij而不是调试直接通过Intellij进行了Docker的部署和管理。

Sheesh Never mind. I didnt really need the Docker Integration plugin. Seems like that is more for deployment and management of Docker directly through Intellij than for debugging.

要调试在Docker容器中运行的码头应用程序，我只需进行远程调试：

To debug my jetty app running inside my docker container, I simply remote debugged:

运行|编辑配置| + |远程

Run | Edit configurations | + | Remote

因为我使用了默认的远程调试选项，所以命令行参数已经可以了。我只需要更改主机设置。在这里，我使用了在Docker容器中设置的主机名

The command line args were already OK since I used the default remote debugging options. I only needed to change the Host settings. Here I used the hostname I had set within the docker container
