To add a DNS record (e.g. a subdomain): 0. Make sure the version on the server matches the version in this repository. If the version on the server is newer, update this repository to match first. Check /etc/powerdns/bind/db.cloyne.org in the dns container on server2.

1. Open etc/powerdns/bind/db.cloyne.org in an editor

2. Increment the Serial number

3. Add the line

4. save and quit

5. Commit/push and wait for Docker hub to update

6. Deploy to server2 according to cloyne/servers

7. On server2, if it doesn't start properly (i.e., pdns_server does not show up in top within the container), exec into the docker container (docker exec -ti dns script -q -c "/bin/bash" /dev/null)

8. edit /etc/powerdns/pdns.conf (you'll probably need to install an editor, either apt install nano or apt install vim-tiny) and change the line launch= to launch=bind. Then add the line bind-config=/etc/powerdns/bindbackend.conf.

9. Restart pdns with sv restart powerdns

10. Run pdns_control reload. Now pdns_control list-zones should show

    40-29.133.62.64.in-addr.arpa. cloyne.net. cloyne.org. All zonecount:3

11. Wait patiently for changes to propagate.
