How to use this image

This image is created starting from the official Nginx Docker image. Look at the "How to use this image" section of the official image readme to learn how to configure and use this image.

Auto-reloading

The image watches for changes in the /etc/nginx/conf.d and /etc/letsencrypt/live directories and reloads Nginx whenewer a file in this directories is added, deleted or updated.

The directories that are watched for changes can be changed by overriding the INOTIFYWAIT_WATCH_DIRSenv variable. E.g.:

INOTIFYWAIT_WATCH_DIRS="/etc/my/dir/one /etc/my/dir/two /etc/my/dir/three"
