Here you can find the code I made with the cloudflare API to automatically update my IP address on the website I self-host
You have to complete these items for the script to work :
- email : the email address of your account
- global_key : The global key of your account, it can be found on https://dash.cloudflare.com/profile/api-tokens
- Zone_ID It is shown at the bottom of the preview tab. Whether you have 1 or more sites, you must fill in this field
- Domain_Name : Your domain name, without any subdomain. F.e : google.com (not
www.google.com) - proxy : If your domain name is proxied by cloudflare, put true, else, put false
- type : Your DNS Type. Default is A if you redirect it to an IPv4 address. F.e : 192.168.15.19
You can use this script on every linux that supports curl and jq packages.
You can install them using (for Ubuntu / Debian based OS) : apt install -y curl jq
I personnaly put the script in the /usr/local/sbin directory, and make a crontab on it with this line :
*/5 * * * * /usr/local/sbin/cloudflare-ddns-update.sh > /dev/null 2>&1
It will check every 5 minutes if the public IP is correct, and if not, it will change it on your cloudflare control panel.
The > /dev/null 2>&1 is to redirect the errors and the output of the program to nowhere, to avoid the display of errors in a log file. (Normally, you shouldn't get any errors)
To add the upper line to the crontab, you only have to type sudo crontab -e in a terminal, and past the line (with changing the directory of your script if you didn't put it in /usr/local/sbin)
Hope you enjoy it, I did it because I couldn't find anything on this website that works, so I decided to make this script by myself
Have a good day !
