> [!NOTE]
> If you enable public network access, it is recommended to use Nginx and other reverse proxy software to enable HTTPS access to ensure security.

## Use in system

- Download and unzip ddns-go from [Releases](https://github.com/jeessy2/ddns-go/releases)
- Run in service mode
  - Mac/Linux: `sudo ./ddns-go -s install`
  - Win(Run as administrator): `.\ddns-go.exe -s install`
- Config
  - Please open the browser and visit `http://localhost:9876` for initial configuration
- [Optional] Uninstall service
  - Mac/Linux: `sudo ./ddns-go -s uninstall`
  - Win(Run as administrator): `.\ddns-go.exe -s uninstall`
- [Optional] Support installation with parameters
  - `-l` listen address
  - `-f` sync frequency(seconds)
  - `-cacheTimes` interval N times compared with service providers
  - `-c` custom configuration file path
  - `-noweb` does not start web service
  - `-skipVerify` skip certificate verification
  - `-dns` custom DNS server
  - `-resetPassword` reset password
- [Optional] Examples
  - 10 minutes to synchronize once, and the configuration file address is specified
    ```bash
    ./ddns-go -s install -f 600 -c /Users/name/.ddns_go_config.yaml
    ```
  - Every 10 seconds to check the local IP changes, every 30 minutes to compare the IP changes, to achieve IP changes immediately trigger updates and will not be limited by the service providers, if the use of api to obtain IP, need to pay attention to the api side of the flow limit
    ```bash
    ./ddns-go -s install -f 10 -cacheTimes 180
    ```
  - reset password
    ```bash
    ./ddns-go -resetPassword 123456
    ```

## Use in docker

- Mount the host directory, use the docker host mode. You can replace `/opt/ddns-go` with any directory on your host, the configuration file is a hidden file

  ```bash
  docker run -d --name ddns-go --restart=always --net=host -v /opt/ddns-go:/root jeessy/ddns-go
  ```

- Please open the browser and visit `http://DOCKER_IP:9876` for initial configuration

- [Optional] Use `ghcr.io` mirror

  ```bash
  docker run -d --name ddns-go --restart=always --net=host -v /opt/ddns-go:/root ghcr.io/jeessy2/ddns-go
  ```

- [Optional] Support startup with parameters `-l`listen address `-f`Sync frequency(seconds)

  ```bash
  docker run -d --name ddns-go --restart=always --net=host -v /opt/ddns-go:/root jeessy/ddns-go -l :9877 -f 600
  ```

- [Optional] Without using docker host mode

  ```bash
  docker run -d --name ddns-go --restart=always -p 9876:9876 -v /opt/ddns-go:/root jeessy/ddns-go
  ```

- [Optional] Reset password

  ```bash
  docker exec ddns-go ./ddns-go -resetPassword 123456
  docker restart ddns-go
  ```

## Webhook
