Change files in running container with volume

[ASchmidt84]

Hi,
this container is the only one which really works.

Now I create a meteor app. But I want to change the stylesheets from outside the container and at running time of the container. Also I want to add a few new pics in public. Is that possible?
And if yes how???

Thank you
