Docker build fails

Archive Windows Server 2016
1

This is my Dockerfile. I am installling some build tools via chocolatey using docker. Whenever, I try to build the dockerfile, I get this error. Is my dockerfile is not correct?

    # Use the latest Windows Server Core image.
    FROM microsoft/windowsservercore

    ENV chocolateyUseWindowsCompression false

    RUN powershell -Command \
        iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1')); \
        choco feature disable --name showDownloadProgress

    RUN choco install visualstudio2015professional
    RUN choco install qtcreator
    RUN choco install curl
    RUN choco install jq
    RUN choco install 7zip.install
    RUN choco install jfrog-cli
    RUN choco install jom

Well clearly your build is unable to reach the Chocolatey url for the install script, and because of that Chocolatey isn’t installed so you see the error …

The term ‘choco’ is not recognized as the name of a cmdlet

So you need to look at your connectivity to

https://chocolatey.org/install.ps1

Proxy maybe ?
