glared's Introduction

Automatically update the A record of your cloudflare domains with your public IPv4 address

Gets the external/public IPv4 Address
Uses the config.yaml to get the auth email, cloudflare token and list of domains
Updates each domain's A record with the public IPv4 address
Supports domains and subdomains, i.e. if you want to update the domain only, set the domain and name to the same value in the config.
If you want to update only a subdomain and not the domain, set the name and domain to a different value, i.e. if your domain is "example.com" and you want to udpate "subdomain.example.com" set the latter as name and the former as domain in the config.yaml

Same config.yaml

domains:
  - domain: "example0.com"
    name: "example0.com"
    zone: "14188253e4f00003d5d45e03pp0ppp23"
    proxied: false
  - domain: "example1.com"
    subdomain: "example1"
    zone: "14188253e4f00003d5d45e03pp0ppp23"
    proxied: false
  - domain: "example2.com"
    name: "example2"
    zone: "14188253e4f00003d5d45e03pp0ppp23"
    proxied: false
  - domain: "example3.com"
    name: "example3"
    zone: "14188253e4f00003d5d45e03pp0ppp23"
    proxied: false
auth:
  key: "14188253e4f00003d5d45e03pp0ppp23"
  email: "[email protected]"

Usage:

go build && ./glared

Should print something like

2023/07/21 12:33:31 IPV4 address hasn't changed, 200.22.20.15 = 200.22.20.15 in example0.com
2023/07/21 12:33:31 IPV4 address hasn't changed, 200.22.20.15 = 200.22.20.15 in example1.example1.com
2023/07/21 12:33:32 IPV4 address hasn't changed, 200.22.20.15 = 200.22.20.15 in example2.example2.com

Motivation: I have a dynamic IP address at home and every time the electricity goes out (used too much power), I have to manually update the A records of all domains hosted at home with cloudflare.
