unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: registry-mirrors: (from flag: [https://7rgqloza.mirror.aliyuncs.com/], from file: [https://7rgqloza.mirror.aliyuncs.com])\n"
docker在centos下如果在/etc/docker/daemon.json里配置镜像源地址就会报错。
