I needed a quick and easy way of sharing files locally. After discovering how flakey Python's inbuilt webserver could be, I decided to put together something in Docker.
The whole image is only about 20MB and most of that comes from the Apache2 tools to generate the .htpasswd on the fly
To build the container, run docker build -t benrlewis/www-share .
To use the container, run the following command
docker run -it --rm -v /path/to/dir:/etc/nginx/html:ro -e PASSWORD=yourpass -p 8080:80 benrlewis/www-share
The container destroys itself when stopped with the --rm flag but this can be disabled.
