[Command Line Parameters](doc/config/cli.en.md) `ddns --key=value` (use `ddns -h` for details), highest priority 2. [JSON Configuration File](doc/config/json.en.md) (null values are considered valid and will override environment variable settings; if no corresponding key exists, environment variables will be used) 3. [Environment Variables](doc/config/env.en.md) with DDNS_ prefix plus key in uppercase or lowercase, dots converted to underscores (`${ddns_id}` or `${DDNS_ID}`, `${DDNS_LOG_LEVEL}`) > 📖 **Environment Variables Documentation**: See [Environment Variables Configuration](doc/config/env.en.md) for detailed usage and examples of all environment variables
config.json Configuration File - A template configuration file will be automatically generated on first run - Use `-c` to specify a configuration file (defaults to config.json in the current directory) - Recommended to use editors that support JsonSchema like VSCode for editing configuration files - See [JSON Configuration File Documentation](doc/config/json.en.md) for complete configuration options and examples ```bash ddns -c path/to/config.json # Or run with Python python -m ddns -c /path/to/config.json # Remote configuration file ddns -c https://ddns.newfuture.cc/tests/config/debug.json ``` #### Configuration Parameters Table | key | type | required | default | description | tips | | :----: | :----------------: | :------: | :---------: | :----------------: | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | id | string | √ | N/A | API Access ID | Cloudflare uses email (leave empty when using Token)

Some providers have [detailed configuration docs](doc/providers/) | | ipv4 | array | No | `[]` | IPv4 Domain List | When `[]`, IPv4 address will not be retrieved and updated | | ipv6 | array | No | `[]` | IPv6 Domain List | When `[]`, IPv6 address will not be retrieved and updated | | index4 | string\|int\|array | No | `"default"` | IPv4 Get Method | Can set `network interface`, `private`, `public`, `regex` etc. | | index6 | string\|int\|array | No | `"default"` | IPv6 Get Method | Can set `network interface`, `private`, `public`, `regex` etc. | | ttl | number | No | `null` | DNS Resolution TTL | Uses DNS default policy when not set | | proxy | string\|array | No | N/A | HTTP Proxy Format: `http://host:port` | Multiple proxies tried sequentially until success, `DIRECT` for direct connection | | ssl | string\|boolean | No | `"auto"` | SSL Certificate Verification | `true` (force verify), `false` (disable verify), `"auto"` (auto downgrade) or custom CA certificate file path | | debug | bool | No | `false` | Enable Debug | Debug mode, only effective with command line parameter `--debug` | | cache | string\|bool | No | `true` | Cache Records | Keep enabled normally to avoid frequent updates, default location is `ddns.cache` in temp directory, can also specify a specific path | | log | object | No | `null` | Log Config (Optional) | Log configuration object, supports `level`, `file`, `format`, `datefmt` parameters | #### index4 and index6 Parameter Description - Numbers (`0`, `1`, `2`, `3`, etc.): The i-th network interface IP - String `"default"` (or no this field): System default IP for external access - String `"public"`: Use public IP (query via public API, simplified URL mode) - String `"url:xxx"`: Open URL `xxx` (e.g., `"url:http://ip.sb"`), extract IP address from returned data - String `"regex:xxx"` Regular expression (e.g., `"regex:192.*"`): Extract the first IP address matching from `ifconfig`/`ipconfig`, **note JSON escaping** (`\` should be written as `\\`) - `"192.*"` matches all IPs starting with 192 (note: `regex:` cannot be omitted) - To match `10.00.xxxx`, write as `"regex:10\\.00\\..*"` (`"\\"` JSON escapes to `\`) - String `"cmd:xxxx"`: Execute command `xxxx` and use stdout output as target IP - String `"shell:xxx"`: Use system shell to run `xxx`, and use stdout result as target IP - `false`: Force disable IPv4 or IPv6 DNS resolution updates - List: Execute index rules in the list sequentially, using the first successful result as target IP - For example, `["public", "regex:172\\..*"]` will first query public API, then look for local IPs starting with 172 if no IP is obtained #### Custom Callback Configuration - `id` field: Fill in callback URL starting with HTTP or HTTPS, HTTPS recommended, supports variable replacement - `token` field: POST request parameters (JSON object or JSON string), use GET request if this field is empty or missing. When JSON parameter values contain constants from the table below, they will be automatically replaced with actual content For detailed configuration guide, see: [Callback Provider Configuration](doc/providers/callback.en.md) | Constant Name | Constant Content | Description | | ---------------- | ---------------------------- | ----------- | | `__DOMAIN__` | DDNS Domain | | | `__IP__` | Obtained corresponding type IP address | | | `__RECORDTYPE__` | DDNS Record Type | | | `__TTL__` | DDNS TTL | | | `__TIMESTAMP__` | Request timestamp | With decimal | #### Configuration Example ```json { "$schema": "https://ddns.newfuture.cc/schema/v4.0.json", "id": "12345", "token": "mytokenkey", "dns": "dnspod or dnspod_com or alidns or aliesa or dnscom or cloudflare or he or huaweidns or namesilo or tencentcloud or noip or callback", "ipv4": ["ddns.newfuture.cc", "ipv4.ddns.newfuture.cc"], "ipv6": ["ddns.newfuture.cc", "ipv6.ddns.newfuture.cc"], "index4": 0, "index6": "public", "ttl": 600, "proxy": ["http://127.0.0.1:1080", "DIRECT"], "log": { "level": "DEBUG", "file": "dns.log", "datefmt": "%Y-%m-%dT%H:%M:%S" } } ```
### Configuration Priority and Field Override Relationship If the same configuration item is set in multiple places, the following priority rules apply: - **Command Line Parameters**: Highest priority, overrides all other settings - **JSON Configuration File**: Between command line and environment variables, overrides environment variable settings - **Environment Variables**: Lowest priority, used when not set by other methods **Advanced Usage:** - JSON configuration file can contain only partial fields, missing fields will use environment variables - Environment variables support both uppercase and lowercase formats - Support for nested configuration through dot notation converted to underscores ### Scheduled Tasks
Use built-in task command to set up scheduled tasks (checks IP every 5 minutes by default for automatic updates) DDNS provides a built-in `task` subcommand for managing scheduled tasks with cross-platform automated deployment: #### Basic Usage ```bash # Install scheduled task (default 5-minute interval) ddns task --install --dns dnspod --id your_id --token your_token --ipv4 your.domain.com # Check task status ddns task --status # Uninstall scheduled task ddns task --uninstall ``` #### Supported Systems - **Windows**: Uses Task Scheduler - **Linux**: Automatically selects systemd or crontab - **macOS**: Uses launchd #### Advanced Management ```bash # Install with custom interval (minutes) ddns task --install 10 -c /etc/ddns/config.json # Enable/disable tasks ddns task --enable ddns task --disable ``` > **New Feature Advantages**: > > - ✅ Cross-platform automatic system detection > - ✅ Automatically overwrites existing tasks without manual uninstallation > - ✅ Supports all DDNS configuration parameters > - ✅ Unified command-line interface For detailed configuration guide, see: [CLI Parameters Documentation](/doc/config/cli.en.md#task-management) #### Docker Docker images, without additional parameters, have a scheduled task enabled by default that runs every 5 minutes
