This repository provides an image for Nginx on Raspberry Pi. Automated builds currently fail since Docker Hub currently doesn't support ARM platforms.
For more details, see https://github.com/ckulka/rpi-nginx
If the environment variable NGINX_NO_UPDATE is present, then Nginx will not be updated prior to starting it, as this saves startup time if necessary.
docker run --rm -it -e NGINX_NO_UPDATE= ckulka/rpi-nginx
Updating Nginx before running it is, however, the default setting.
A sample docker-compose.yml file can be found in the git repo: https://github.com/ckulka/rpi-nginx
