Windows的Docker桌面:在Windows容器模式下无法访问裸露端口上的服务 [英] Docker Desktop for Windows: cannot access service on exposed port in windows container mode

问题描述

我正在使用以下 Dockerfiles 在运行 Docker Desktop for Windows 版本17.03

I am using the following Dockerfiles to create a container running Jenkins in a windows container on Windows 10 desktop running Docker Desktop for Windows version 17.03

FROM microsoft/windowsservercore

RUN powershell -Command wget 'http://javadl.oracle.com/webapps/download/AutoDL?BundleId=210185' -Outfile 'C:\jreinstaller.exe' ; Start-Process -filepath C:\jreinstaller.exe -passthru -wait -argumentlist "/s,INSTALLDIR=c:\Java\jre1.8.0_91" ; del C:\jreinstaller.exe

ENV JAVA_HOME c:\\Java\\jre1.8.0_91  
RUN setx PATH %PATH%;%JAVA_HOME%\bin

CMD [ "java.exe" ]

我从此docker文件创建映像:

I create the image from this docker file:

docker build -t windows-java:jre1.8.0_91 .

我用来在此之上安装Jenkins的第二个Dockerfile:

The second Dockerfile I am using to install Jenkins on top of this:

FROM windows-java:jre1.8.0_91

ENV HOME /jenkins  
ENV JENKINS_VERSION 2.58  
RUN mkdir \jenkins  
RUN powershell -Command "wget -Uri https://updates.jenkins-ci.org/latest/jenkins.war -UseBasicParsing -OutFile /jenkins/jenkins.war"

EXPOSE 8080  
EXPOSE 50000  

CMD java -jar C:\\jenkins\\jenkins.war


docker build -t jenkins-windows:2.0 .

然后我像这样启动容器:

Then I launch the container like this:

docker run --name jenkinsci -p 8080:8080 -p 50000:50000  jenkins-windows:2.0

我可以看到容器运行良好，并且日志显示一切正常

I can see the container running fine and logs showing up all good

PS C:\Users\mandeep\ringba\ringba-jenkins-setup-windows\jenkins-master> docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                                              NAMES
85ba2ef525a1        jenkins-windows:2.0   "cmd /S /C 'java -..."   8 hours ago         Up 8 hours          0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp   jenkinsci

但是，我无法访问在主机Web浏览器上的http://localhost:8080上运行的jenkins服务器.

However, I cannot access the jenkins server running on http://localhost:8080 on the host machine's web browser.

不确定是否有帮助，但是当我在同一台计算机上以Linux container模式运行docker时，我能够访问http://localhost:8080上的jenkins服务器 使用他们的官方docker映像.

Not sure if it helps but when I was running docker in Linux container mode on the same machine, I was able to access jenkins server on http://localhost:8080 using their official docker image.

推荐答案

这是Windows上目前已知的问题.无法使用localhost/127.0.0.1.从其自己的主机访问容器终结点.今天可以使用Linux容器，因为Docker包含了一种特殊的变通方法，这种变通方法是Moby/Linux实施所特有的，可以在Windows上运行Linux容器.

This is a currently a known issue on Windows. It's not possible to access a container endpoint from its own host using localhost/127.0.0.1. It is possible using Linux containers today because Docker has included a special workaround that is unique to their Moby/Linux implementation for running Linux containers on Windows.

我们正在为此进行修复，但是今天我们建议通过以下任一方法来解决此问题:

We're working on a fix for this, but today we recommend working around this by either:

• 使用运行容器的主机的IP地址以及容器在其主机上的公开端口，从单独的主机访问容器端点
通过使用容器的内部IP地址和发布的端口访问相同主机上的容器，以进行
• OR(可以使用docker network inspect <network name>或docker exec <container ID> ipconfig>来获取容器端点本身的IP地址)

• Accessing container endpoints from a separate host, using the IP address of the host that is running the container, and the exposed port for the container on its host
• OR by accessing the container on the same host, using the container's internal IP address and published port (you can use docker network inspect <network name> or docker exec <container ID> ipconfig> to get the IP address of the container endpoint itself)
