This docker permit to automatically update all my docker containers. By default is done every 5 minutes. This created more than 10000 DNS requests per day. Thanks, Pi-Hole to flag me the requests (domains used registry-1.docker.io and auth.docker.io).
The 5 minutes was definitely overkilling for my usage. I decided to do the process only every day at 7 PM.
Recenlty, I added the notofication using ntfy.sh. It's very nice to be aware about all the update.
