From the Cloudflare side, add desired subdomain you want to map.
Put a dummy IP address (127.0.0.1), deactivate orange cloud and click Add Record.
Next, from My profile page get Global API Key.
On a machine with a dynamic public ip, install ddclient with:
sudo apt update sudo apt install ddclient libjson-any-perl
Check for run_daemon=”true” and update daemon_interval to preferred value, default is 300 seconds.
# Configuration for ddclient scripts # generated from debconf on Fri 24 Nov 21:37:56 EET 2017 # # /etc/default/ddclient # Set to "true" if ddclient should be run every time DHCP client ('dhclient' # from package isc-dhcp-client) updates the systems IP address. run_dhclient="false" # Set to "true" if ddclient should be run every time a new ppp connection is # established. This might be useful, if you are using dial-on-demand. run_ipup="false" # Set to "true" if ddclient should run in daemon mode # If this is changed to true, run_ipup and run_dhclient must be set to false. run_daemon="true" # Set the time interval between the updates of the dynamic DNS name in seconds. # This option only takes effect if the ddclient runs in daemon mode. daemon_interval="60"
Insert valid email, API Key and update the subdomains you want to update in
# Configuration file for ddclient generated by debconf # # /etc/ddclient.conf ## ### CloudFlare config ### ssl=yes use=web, web=dyndns protocol=cloudflare, server=www.cloudflare.com login=INSERT_CLOUDFLARE_EMAIL password=INSERT_CLOUDFLARE_API_TOKEN # set domain and subdomain to update zone=domain1.com sub1.domain1.com # OPTIONAL # sub2.domain1.com # OPTIONAL # zone=domain2.com # sub1.domain2.com
Test current config with:
sudo ddclient -daemon=0 -debug -verbose -noquiet
Restart ddclient service:
sudo service ddclient restart
Now ddclient is up and running as is checking for DNS updates every 60 seconds.
Check service status with:
sudo service ddclient start
These instructions have been tested on ubuntu 16.04 and raspberry pi with raspbian stretch.
- pack the service as a docker container, run service from a single command.
