gandi-live-dns-rust
A program that can set the IP addresses for configured DNS entries in Gandi's domain configuration. Thanks to Gandi's LiveDNS API, this creates a dynamic DNS system.
If you want to host web services but you don't have a static IP address, this tool will allow you to keep your domains pointed at the right IP address. This program can update both IPv4 and IPv6 addresses for one or more domains and subdomains. It's a one-shot tool that's meant to be managed with a systemd timer or cron.
Usage
The Gandi Live DNS API is rate limited at 30 requests per minute. This program respects this rate limit: if you have more than 30 domains to update, the program will pause and wait for a minute, plus a random delay to ensure it doesn't hit the rate limit.
System packages
Packages are available for some linux distributions.
- ArchLinux: gandi-live-dns-rust on AUR
Contributions to release this for other distributions are welcome!
Prebuilt binaries
gandi-live-dns
provides pre-built binaries with the releases. See the
releases page to
get the latest version. These binaries are statically linked, and provided for
both Linux and Windows, including ARM architectures for the Linux version.
Download the latest version from the releases page, extract it from the archive, and place it somewhere in your $PATH
to use it.
- Create a file
gandi.toml
, then copy and paste the contents ofexample.toml
- Follow the instructions in the example config to get your API key and put it in the config
- Follow the examples in the config to set up the entries you want to update
- Run
gandi-live-dns
inside the directory with the configration to update your DNS entries
With docker
Use the seriousbug/gandi-live-dns-rust Docker images, which are available for x86_64, arm64, armv6, and armv7 platforms. Follow the steps below to use these images.
- Create a file
gandi.toml
, then copy and paste the contents ofexample.toml
- Follow the instructions in the example config to get your API key and put it in the config
- Follow the examples in the config to set up the entries you want to update
- Run
docker run --rm -it -v $(pwd)/gandi.toml:/gandi.toml:ro seriousbug/gandi-live-dns-rust:latest
Docker doesn't support IPv6 out of the box. If you need to update IPv6 addresses, check the linked page to enable IPv6 or use the prebuilt binaries directly.
If you get errors about not finding the config file, make sure your command has a full path to the config file (
$(pwd)/gandi.toml
part). Otherwise Docker will create a directory.
Automation
The Packaging
folder contains a Systemd service and timer, which you can use
to automatically run this tool. By default it will update the IP addresses after
every boot up, and at least once a day. You can adjust the timer to speed this
up, but avoid unnecessarily overloading Gandi's servers.
- Place
gandi-live-dns.timer
andgandi-live-dns.service
into/etc/systemd/system
- Put
gandi-live-dns
binary into/usr/bin/
- You can also place it in
/usr/local/bin
or some other directory, just make sure to update the path in the service file
- You can also place it in
- Create the folder
/etc/gandi-live-dns
, and place yourgandi.toml
into it - Create a user for the service:
useradd --system gandi-live-dns --home-dir /etc/gandi-live-dns
- Make sure only the service can access the config file:
chown gandi-live-dns: /etc/gandi-live-dns/gandi.toml && chmod 600 /etc/gandi-live-dns/gandi.toml
- Enable the timer with
systemctl enable --now gandi-live-dns.timer
Development
Local builds
cargo build
and cargo build --release
are sufficient for development and release builds.
No special instructions are needed.
Making a release
To make a release, first set up cross
and docker
. Make sure you log into
Docker with docker login
. Then follow these steps:
- bump up the version in
Cargo.toml
according to semver- commit and push the changes
- run
./make-release.sh
This will build binaries, then package them into archives, as well as build and upload docker images.
- Create a release on Github
- Make sure to create a tag for the release version on
master
- Upload the binary archives to the Github release
- Make sure to create a tag for the release version on
- Update the AUR version manually
