A very simple NGINX image server based off the stack overflow question here: https://stackoverflow.com/questions/39575873/is-there-a-way-to-create-a-simple-static-image-gallery-in-nginx-without-any-thir
This service allows a user to browse the contents of directories as galleries with image thumbnails. Each thumbnail also links to the image directly to show it fullsize.
To run this service, simply build and launch the container with a port binding to 8000 and mount the directory you wish to share /var/www:
docker build -t image_server .
docker run -p 8000:8000 -v /local/path/to/gallery:/var/www image_server
The service will now be avalible to browse at http://localhost:8000/
