A Linux client for dynamic-cloud-dns project

Dynamic Cloud DNS Client

This is a simple client for the Dynamic Cloud DNS project.

Designed to run under Linux systemd, it consists of a small Python script, which uses the ipify API to retrieve the current IP and if the IP address has changed, calls the cloud function configured as per the instructions for Dynamic Cloud DNS.

Prerequisites

Needs Python 3, requests and backoff

pip3 install -r requirements.txt

Setup

• Copy dynamic_cloud_dns_client.py to /usr/local/bin
• Copy dynamic-cloud-dns-client@.service to /etc/systemd/system
• Copy dynamic_cloud_dns_client_your.host to /etc (replace your.host with your actual hostname)
• Edit dynamic_cloud_dns_client_your.host and fill in the environment variables
• Enable and start your service: systemctl enable [e-mail]

Run sudo ./install.sh your.host to do the first 3 steps. Run just sudo ./install.sh to do the first two steps.

Testing

Probably a good idea to do this in a virtualenv:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
pip install -t test-requirements.txt
pytest
