Docker DDNS Cloudflare

Features 🌈

• Simple container for setting setting and updating cloudflare records to your local ip address.
• Only makes requests if the IP has changed.
• By default it runs once every minute and the IP is resolved by https://api.ipify.org/.

Quickstart 🚀

1. Get your api token here (Top right -> My Profile -> API Tokens)

Click create token. You can then use the Edit DNS Zone template. Give it a name.

2. Create an .env file:

EMAIL=my@mail.com
KEY=my_api_key
ZONE=example.org
DNS_RECORD=some.example.org

3. Run the container

docker run -d --name ddns --restart always --env-file .env cupcakearmy/ddns-cloudflare

To check logs:

docker logs ddns

Docker-Copmose

With docker-compose:

git clone https://github.com/CupCakeArmy/docker-ddns-cloudflare.git
cp .sample.env .env
# Edit the .env file with your data
docker-compose up -d

Customize

Custom CRON

By default the script runs every 5 minutes. You can customize this by simply setting the CRON value in the .env file.

# .env

# e.g. every minute
CRON=* * * * *

Custom Resolver

By default the script checks the own ip by calling https://api.ipify.org/. This also can be configured. It has to be an endpoint that return a plain text containing the ip by get request.

# .env
