解决群晖NAS UI(或SSH中)的docker pull错误(无法拉取, 注册表错误)

朗读全文

有什么用

error pulling image configuration: Get "https://production.cloudflare.docker.com/registry-v2/docker/registry/v2/...

dial tcp 128.242.250.148:443: i/o timeout

该方法适用于：

怎么用

群晖 7.1 和 7.1.1，没有 ContainerManager ，Mac 上开 clash 允许 Lan 访问，配置下代理：

目录：/usr/local/lib/systemd/system

vim pkg-Docker-dockerd.service

[Service]
Environment="HTTP_PROXY=http://192.168.1.10:7890"
Environment="HTTPS_PROXY=http://192.168.1.10:7890"
Environment="NO_PROXY=localhost,127.0.0.1"

（请根据自己情况，适当修改这个文件内容）

systemctl daemon-reload
systemctl restart pkg-Docker-dockerd

测试成功，测试过程如下：

root@DS918:/usr/local/lib/systemd/system# docker pull ryjer/opentracker

实现方法

通过ssh命令控制重启Docker服务或者直接重启机器

NAS停用Docker套件

bash /var/packages/Docker/scripts/start-stop-status stop

NAS开启Docker套件

bash /var/packages/Docker/scripts/start-stop-status start

老版本的群晖NAS

方法一：

1. 添加 /etc/docker/env 文件
   export HTTP_PROXY=127.0.0.1:8899

2. 编辑 /etc/init/pkg-Docker-dockerd.conf 文件
   将
   exec /var/packages/Docker/target/usr/bin/dockerd --config-file /var/packages/Docker/etc/dockerd.json
   改为

#exec /var/packages/Docker/target/usr/bin/dockerd --config-file /var/packages/Docker/etc/dockerd.json
script
source /etc/docker/env
/var/packages/Docker/target/usr/bin/dockerd --config-file /var/packages/Docker/etc/dockerd.json
end script

3. 然后，重启 docker 服务，
   1. 停止 docker
      1. /var/packages/Docker/scripts/start-stop-status stop
   2. 启动 docker
      1. /var/packages/Docker/scripts/start-stop-status start

接着，你就尽情的 pull 吧，速度拉满

方法二：

1. 删除 NAS 》 控制面板 》网络 》代理服务器
2. 手动配置DNS服务器
   1. 223.5.5.5
   2. 114.114.114.114
3. 设置 Docker 》 注册表 》设置
   1. https://registry.cn-hangzhou.aliyuncs.com/
   2. https://docker.nju.edu.cn
4. 清空 /etc/docker/daemon.json

方法三：
