In Docker (for Windows) How can I add registry ent

Question

I'm using Docker for Windows and building the docker image with a Dockerfile like this:

FROM mydockerhublogin/win2k16-ruby:1.0

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app


# Make port 80 available to the world outside this container
EXPOSE 80

# Define environment variable
ENV NAME World

RUN powershell -Command \
    $ErrorActionPreference = 'Stop'; \
  New-Item "HKLM:\Software\WOW6432Node\ExampleCom" -Force ; \
  New-ItemProperty "HKLM:\Software\WOW6432Node\ExampleCom" -Name MenuLastUpdate -Value "test" -Force

RUN powershell -Command \
    $ErrorActionPreference = 'Stop'; \
  New-Item "HKLM:\Software\ExampleCom" -Force ; \
  New-ItemProperty "HKLM:\Software\ExampleCom" -Name MenuLastUpdate -Value "test" -Force
# Run ruby script when the container launches
CMD ["C:/Ruby23-x64/bin/ruby.exe", "docker_ruby_test.rb"]

Note that I am adding some registry entries to the Windows registry which the code inside the container will access. While this method of adding registry entries is fine for a few entries, my requirement is to add dozens of entries required for my windows application. Is there a way to do this in a more concise manner?

Answer 1

Try creating a file for the your registry entry and copy that inside the container.

Then try running Invoke-Command -ScriptBlock {regedit /i /s C:\shared\settings.reg}
