GIU

Gandi LiveDNS Updater - Command line tool to keep your dynamic ip up to date.

Prequisites

• A valid key fro Gandi LiveDNS API. Use https://account.gandi.net/en/users/USER/security (USER is your Gandi user account).
• Python 3.

Installation

The recommended way to install this package is through pip.

pip install --user giu

Usage

To use giu you need to create a config.toml file to hold the minimal set of configurations.

[api]
url = 'https://dns.api.gandi.net/v5/livedns'
key = 'YOUR_KEY'

[dns]
domain = 'example.com'
records = [
    {'type' = 'A', 'name' = '@', 'ttl' = 18000},
    {'type' = 'A', 'name' = '*', 'ttl' = 1800},
]

[resolver]
providers = [
    'http://ipecho.net/plain',
    'https://ifconfig.me/ip',
    'http://www.mon-ip.fr'
]

Docker Compose

In this example the config is in the current folder.

docker-composer up -d

By default the process will check your configuration every hour and update it if the process detects a drift in the desired state.

One shot

In this example the config file was created on $HOME/.giu/example.com.toml.

giu sync --conf $HOME/.giu/example.com.toml

Cronjob

In this example the config file was created on $HOME/.giu/example.com.toml.

$ crontab -e
* */2 * * * giu sync --conf $HOME/.giu/example.com.toml

Docker

In this example a config file in the $PWD folder is mounted in /app/conf and the command runs in dry-run mode.

docker run -it --rm -v $PWD:/app/conf yriveiro/giu:dev giu sync --dry-run --config /app/conf/config.toml

✔ Dynamic IP fetched.
ℹ Current dynamic IP: XXX.XXX.XX.XX.
ℹ Dry run mode on.
ℹ TTL for 'A' record '@' on config: 1800
✔ 'A' record '@' for foo.bar from Gandi LiveDNS
ℹ IP for 'A' record '@' on Gandi LiveDNS: XXX.XXX.XXX.XXX
ℹ TTL for 'A' record '@' on Gandi LiveDNS: 18000
ℹ Update needed, dry run mode, no update done.
ℹ TTL for 'A' record '*' on config: 1800
✔ 'A' record '*' for toranja.tech from Gandi LiveDNS
ℹ IP for 'A' record '*' on Gandi LiveDNS: XXX.XXX.XXX.XXX
ℹ TTL for 'A' record '*' on Gandi LiveDNS: 1800
ℹ Update needed, dry run mode, no update done.

/app/conf folder is not configurable once the Docker image has hardening applyed and that is the writable folder.

Improvements

Some improvements that I have ff the top of my head:

• put command to create entries like CNAMES and so on.
• delete command to delete entries
• backup command to do backups
• Docker Image to run giu with docker compose or as a Cronjob on Kubernetes.
