This is a Sass watcher.
To use it, mount your source
.sass files folder in this image's
and run the container. While it's running,
.css files will be written there,
watching for your changes.
docker run -v $(pwd)/my-sass-files-folder:/app yajo/sass
Watching or running once
The default command is supposed to watch your filesystem for changes, but if
you only want to run it once (or the watcher does not work for some unknown
reason), you can call
update-scss to run the compiler once
Of course, those are only shortcuts with some default options for the
scss compilers. You can pass additional options to those shortcuts or
just call the compilers directly with any arguments you need.
