The Docker containers are deployed and accessible from the outside world - nice! But opening pages of certain services in the internet browser reporting "Your connection is not secure". This happens because of missing SSL certificates. A reverse proxy in front of multiple docker services allows a mapping from subdomains to IP/ports in your local network.

The boot process is in two steps, the first step is starting from the internal flash and mounting the external root filesystem. The second step is booting further from external rootfs.
