ipster

ipster is a command line tool that keeps your CloudFlare DNS record in sync with your Raspberry Pi's IP 🤝

Install and Run

wget https://github.com/anze3db/ipster/releases/download/24.1/ipster.pi
chmod +x ./ipster.pi
./ipster.pi

ipster will need access to your CloudFlare account so you'll have to create an API_TOKEN (use the Edit Zone DNS template).

Run with the necessary environment variables:

IPSTER_CLOUDFLARE_API_TOKEN=xxxxxxxxx_yyyyyyyyyyyyyyyyyyyyyyyyyyyyyy IPSTER_CLOUDFLARE_ZONE_NAME=example.com IPSTER_CLOUDFLARE_DNS_RECORD_NAME=home.example.com ./ipster.pi

Required environmental variables:

• IPSTER_CLOUDFLARE_API_TOKEN - your CloudFlare API_TOKEN (Use the Edit zone DNS template).
• IPSTER_CLOUDFLARE_ZONE_NAME - your CloudFlare zone name. Usually your domain name e.g. example.com.
• IPSTER_CLOUDFLARE_DNS_RECORD_NAME - the CloudFlare DNS record that you want to keep in sync e.g. home.example.com.

Example run

ipster will compare your machine's IP address to the IP address in the DNS Record in CloudFlare and update the DNS Record if the two don't match.

IPSTER_CLOUDFLARE_API_TOKEN=xxxxxxxxx_yyyyyyyyyyyyyyyyyyyyyyyyyyyyyy IPSTER_CLOUDFLARE_ZONE_NAME=example.com IPSTER_CLOUDFLARE_DNS_RECORD_NAME=home.example.com ./ipster.pi
