DockerFile的一些问题

Question

Hello I have a problem with setting up a dockerFile. I want to say that I am new under docker. here is the docker version

C:\>docker version
Client:
Version:      18.03.1-ce
API version:  1.37
Go version:   go1.9.5
 Git commit:   9ee9f40

 Engine:
  Version:      18.03.1-ce
  API version:  1.37 (minimum version 1.24)
  Go version:   go1.9.5

I created a docker image in which I copied an executable. I manage to run the .exe in a container by starting it . Currently I would like to automate things using a dockerFile. My image is called bt1: version1 it is based on microsoft / windowsservercore.

Here is my dockerFile in question.

The goal is to start a container then inside to modify the file test.xml then to launch the application BT_simulator.exe.

FROM bt1:version1
WORKDIR "/BTsimulatorV1.1/release"
RUN powershell.exe
RUN "$doc = [xml](Get-Content /BTsimulatorV1.1/release/test.xml) 
&& $doc.parameters.connection.port = " " 
&& $doc.parameters.connection.ipAddress = " " 
&& $doc.parameters.Tool_EEPROM.Serial_Number = " " 
&& $doc.save("/BTsimulatorV1.1/release/test.xml") 
&& BT_simulator.exe

I do not have to achieve the expected behavior. Can you help me please?

Answer 1

The manipulation of the xml file should not be done in the Dockerfile. The Dockerfile runs only once, during image build. What you need is an ENTRYPOINT script which will do the file manipulation and start the exe.

Everything from RUN powershell.exe onwards should be deleted. The script should be put into an .ps script and ADDed to the image. Then call it with ENTRYPOINT.
