Appending to PATH in a Windows Docker container

Question

I need to append to the PATH within a Windows Docker container, and I\'ve tried many permutations.

ENV PATH=%PATH%;C:\\\\Foo\\\\bin
ENV PATH=$PATH;C:\\\\Foo\         


        

Answer 1

Unfortunately ENV won't work, because windows environment variable work a little differently than linux. more info

As of now the only way to do this is through RUN

But you don't need to create a separate file to do this. This can be done by the following much simpler one line command:

RUN setx path "%path%;C:\Foo\bin"
