记录使用ddclient配置ddns的方法

1. 安装 docker

目前很多发行版自带的ddclient包版本都太老了，而ddclient又是c语言写的安装比较麻烦，用docker是最方便的，如果机器内存很少可以试下nerdctl

2. 使用docker-compose

docker-compose.yaml：

yaml
---
services:
  ddclient:
    image: lscr.io/linuxserver/ddclient:latest
    container_name: ddclient
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Hong_Kong
    volumes:
      - /root/ddclient/config:/config
    restart: unless-stopped

docker compose up -d启动

3. cloudflare创建api token

待补充

4. 修改ddclient配置

/root/ddclient/config/ddclient.conf

conf
daemon=120                              # check every 300 seconds
syslog=yes                              # log update msgs to syslog
#mail=root                              # mail all msgs to root
#mail-failure=root          # mail failed update msgs to root
pid=/var/run/ddclient/ddclient.pid      # record PID in file.
ssl=yes                                 # use ssl-support.  Works with
                                                # ssl-library
use=web, web='https://cloudflare.com/cdn-cgi/trace', web-skip='ip=' # found after IP Address
##
## CloudFlare (www.cloudflare.com)
##
protocol=cloudflare
zone=your.domain
ttl=1
login=token # Only needed if you are using your global API key. If you are using an API token, set it to "token" (wihtout double quotes).
password=your_token # This is either your global API key, or an API token. If you are using an API token, it must have the permissions "Zone - DNS - Edit" and "Zone - Zone - Read". The Zone resources must be "Include - All zones".
sub.your.domain

修改后重启服务

docker compose down
docker compose up -d
