为casaos系统安装openclaw，解决访问docker仓库的问题

在casaos上看到有openclaw，但是安装的时候报错：

Error response from daemon: unknown: failed to resolve reference "docker.io/icewhaletech/openclaw:2026.5.7": unexpected status from HEAD request to https://vrtulz5k.mirror.aliyuncs.com/v2/icewhaletech/openclaw/manifests/2026.5.7?ns=docker.io: 403 Forbidden

1、修改/etc/docker/daemon.json

{
  "registry-mirrors": [
        "https://vrtulz5k.mirror.aliyuncs.com",
        "https://docker.m.daocloud.io",
        "https://dockerproxy.com",
        "https://docker.086181.xyz",
        "https://do.nark.eu.org"
    ],
    "ipv6":true,
    "fixed-cidr-v6":"2409:8a62:31c:c860::/64",
    "experimental":true,
    "ip6tables":true
}

修改后：设置了***** ver**ge代理

{
  "registry-mirrors": [
    ],
    "proxies": {
       "http-proxy": "http://192.168.3.x:7897",
       "https-proxy": "http://192.168.3.x:7897",
       "no-proxy": "localhost,127.0.0.1,172.17.0.0/16,192.168.0.0/16"
    },
    "ipv6":true,
    "fixed-cidr-v6":"2409:8a62:31c:c860::/64",
    "experimental":true,
    "ip6tables":true
}

　如果自己没有proxy，那就用docker.xuanyuan.me镜像，但是有流量限制，很烦

    "https://docker.xuanyuan.me",
    "https://docker.1ms.run",
    "https://docker.m.daocloud.io",

　　使用：docker pull docker.io/icewhaletech/openclaw:2026.5.7，先试下
