Important notice This project will be archived, as the cloudflare-dyndns now has all the functionality covered by the scripts here, save checking for IPv6 updates.
This ddclient script is the client side https://github.com/1rfsNet/Fritz-Box-Cloudflare-DynDNS. For deploying it, a server endpoint is needed.
It is designed to work as a cronjob.
For setting up the script, copy the example config and set your configuration.
Alternatively you can configure the script via enviroment variables.
By default the script will source the config file in the same folder as the script as config_cloudflare_dyndns.sh.
Additional config options that can be added to the config file are:
# Cache where the current IPv4/6 address is stored to avoid unnecessary calls to the server.
CACHE_IPv6="${CACHE_IPv6:-$basedir/.cache_IPv6.txt}"
CACHE_IPv4="${CACHE_IPv4:-$basedir/.cache_IPv4.txt}"
# Config file to source
CONFIG_FILE="${CONFIG_FILE:-$basedir/config_cloudflare_dyndns.sh}"
For running the script regulary, setup a cronjob with crontab -e.
Example:
*/5 * * * * /ddclient/cloudflare_dyndns.sh
This will run the script every 5 minutes.
You can use the image as a docker container, simply run:
docker run -d -v ./config_cloudflare_dyndns.sh:/config/config.sh ghcr.io/heathcliff26/ddclient:latest
You can configure the delay in minutes between updates with DELAY, the default is 5 minutes.
Example for 10 minutes delay:
docker run -d -v ./config_cloudflare_dyndns.sh:/config/config.sh -e DELAY=10 ghcr.io/heathcliff26/ddclient:latest
Additional Variables:
NODE_NAME
BASE_DOMAIN
If both are set and DOMAINS is empty, entrypoint.sh will create the variable by combining both. Used for running the container as a Daemonset in Kubernetes.
Make sure the config file is executable.
Other things i have for ddclient stuff:
-
There are configuration files for the ddclient package against strato under the examples.
-
The script
monitorIPv6.shcan be used to monitor ULA IPv6 addresses. For example with the prefixfd00::.
