HTTP Strict Transport Security Redirect

A Docker image that sets the HSTS header and redirects to the HTTPS url.

Use with Synology

I feel like this could be useful for a bunch of things, but I use it on my Synology NAS to completely shut off port 80.

Build, Save and Upload the Image

docker build -t hsts .
sudo docker save hsts:latest | gzip > hsts.tar.gz

Launch the Container

The only thing to keep in mind here is that you need to select "Use the same network as Docker Host" in the Synology UI. This is so that the container can forward LetsEncrypt requests back to Synology.

Forward the Port

Now you need to forward port 80 at your firewall/router to port 6854 on your Synology NAS.
