synology为container-manager设置daemon.json

Posted on Views:

目的

支持修改类daemon.json文件，从而影响dockerd进程参数，添加insecure-registries。

env

  • ds920+
  • synology DSM 7.2.2-72806 Update 1

解决

DSM 7.2中Docker已经更名为Container Manager:
/var/packages/ContainerManager/etc/daemon.json

根据实验发现不生效，docker info验证

1.container-manager配置目录

cd /var/packages/ContainerManager/etc

2. 修改dockerd.json

        "https://dhub.kubesre.xyz",
        "https://atomhub.openatom.cn"
    ]
}

3.重启container-manager服务

systemctl restart pkgctl-ContainerManager
