Azure Dynamic DNS

Installation

pip install azure-ddns

Run

You can run the cli tool with all the parameters like this

azure-ddns --subscription-id your_ubscription_id --tenant-id your_tenant_id --client-id your_client_id --client-secret your_client_secret --resource-group your_ressource_group_name --zone your_zone_name --record your_record-name

You can also use a json file

azure-ddns --config path/to/your/config.json

The json should be formated like this:

{
    "subscriptionId": "",
    "resourceGroup": "",
    "zoneName": "",
    "recordName": "",
    "clientId": "",
    "clientSecret": "",
    "tenantId": ""
}

CLI flags take priority over the config file, which takes priority over environment variables (AZURE_SUBSCRIPTION_ID, AZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET). If tenant/client id/secret aren't all resolved, DefaultAzureCredential is used instead (managed identity, Azure CLI login, etc.).

Run continuously

By default the tool checks the IP once and exits. Pass --interval-seconds (or set AZURE_DDNS_INTERVAL_SECONDS) to run forever, checking on that interval and only calling the Azure DNS API when the public IP changed:

azure-ddns --config path/to/your/config.json --interval-seconds 300

Use --log-level (or LOG_LEVEL) to control verbosity (DEBUG, INFO, WARNING, ERROR; defaults to INFO).
