Adding a symlink inside the image

Hello there.

I’m sure I’m doing something silly, but I can’t seem to create a symlink in my image,which will then be present in my running container based on that image.

Here’s the relevant bit of the Dockerfile.

RUN mkdir /code
ADD . /code/
RUN pip install -r requirements.txt
RUN ln -s /usr/local/lib/python2.7/dist-packages/django/contrib/admin/media /code/static/media/admin

The output from the build command says it’s doing it without errors, but when I then fire up the container with docker-compose, there is no symlink at that location.

Should I even be doing it in the Dockerfile, or in docker-compose.yml, and is that the correct syntax?

If I docker exec into the running container, running that exact code does create the symlink.

Thanks for any help or tips.

You can also try it to run with “docker run” command. I had the same issue you can call it something like this

docker exec 9ede507fa042 /bin/bash -c ‘uwsgi --ini /usr/src/app/nsfw/config/nsfw_uwsgi.ini --callable app && service nginx start’

I have run this after run in my case but I think you can run the same symlink script with “docker run” command as well.

Hope helps
