In short, what is the right way to achieve the same result as
ENV PATH=/usr/local/texlive:${PATH}
would have produced when placed in Dockerfile by using docker commit --change "ENV ..." flag?
Documentation states that --change flag supports ENV instruction and so I have tried following notations but none of them has worked:
docker commit -c "ENV PATH /usr/local/texlive/bin:${PATH}" 3b459018aa84 test-changes
docker commit -c 'ENV PATH /usr/local/texlive/bin:${PATH}' 3b459018aa84 test-changes
docker commit -c "ENV PATH=\"/usr/local/texlive/bin:${PATH}\"" 3b459018aa84 test-changes
docker commit -c 'ENV PATH=\"/usr/local/texlive/bin:${PATH}\"' 3b459018aa84 test-changes
docker commit -c 'ENV PATH="/usr/local/texlive/bin:${PATH}"' 3b459018aa84 test-changes
docker commit -c 'ENV PATH="/usr/local/texlive/bin:${PATH}"' -p=false 3b459018aa84 test-changes
For more detailed description and outputs of those commands you can check my SO question.
