Too many certificates already issued

Mozilla IoT
#1

Every time I launch the gateway in Docker (trying different launch parameters) I have to reclaim my domain. Maybe I have done this too many times? Now I get…
Failed to generate certificate: Error: Error creating new order :: too many certificates already issued for exact set of domains: arzachena.mozilla-iot.org: see https://letsencrypt.org/docs/rate-limits/

I’ve hit that error many times! Two things:

  1. If you look at the URL linked in that error message, it says the following:

    Renewals are treated specially: they don’t count against your Certificates per Registered Domain limit, but they are subject to a Duplicate Certificate limit of 5 per week.

  2. If you mount something to /home/node/.mozilla-iot in the container, as the README shows, you won’t have to reclaim your domain every time you restart the container.
