Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

 

解决办法:

这是daemon.json 配置的文件格式的错误，

重新修改daemon.json 如下，

# cat daemon.json
{
  "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"],
  "insecure-registries": ["ip"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"
}
# 

重启服务即可！

#systemctl daemon-reload

#systemctl restart docker.service
