Question

当我尝试创建Windows docker container时，设置路径时出现错误我尝试了不同的方法，但是所有尝试都失败了，请建议docker文件问题。我确定设置路径有问题如果我不添加系统路径，那就用java，jboss path结束如何避免这个问题

Answer 1

所以它不起作用的原因是因为您set your shell form对PowerShell和PowerShell的环境变量调用看起来与CMD的调用不同。

FROM mcr.microsoft.com/windows/servercore:ltsc2016

# This is where you're setting the form
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]


COPY jre1.8.0_45.zip c:\\jre1.8.0_45.zip
COPY jboss-eap-7.0.zip c:\\jboss-eap-7.0.zip

# Because you're already in powershell, you can simplify these
#RUN powershell Expand-Archive -Force c:\\jre1.8.0_45.zip c:
#RUN powershell Expand-Archive -Force c:\\jboss-eap-7.0.zip c:

RUN Expand-Archive -Force c:\\jre1.8.0_45.zip c:
RUN Expand-Archive -Force c:\\jboss-eap-7.0.zip c:


 
ENV JAVA_HOME "c:\jre1.8.0_45"
ENV JBOSS_HOME "c:\jboss-eap-7.0" 

#ENV path %path%";C:\jre1.8.0_45\bin;C:\jboss-eap-7.0\bin"
#RUN setx PATH "C:\jre1.8.0_45\bin;C:\jboss-eap-7.0\bin;%PATH%"

# In PowerShell, instead of %PATH% you would use $env:Path
# RUN setx /M PATH "c:\jre1.8.0_45\bin;%PATH%"

RUN setx /M PATH "c:\jre1.8.0_45\bin;$env:Path"

Answer 2

我不构建Windows Docker容器，仅构建Linux容器，所以我不知道您是否可以这样做。但是，使用该映像时，您将始终具有相同的Path，因此您无需使用％PATH％。您可以只生成Docker映像，查看默认路径是什么，然后在Dockerfile中使用c：\ jre1.8.0_45对其进行硬编码。

干杯。
