配置阿里云镜像加速，执行docker命令出错Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the doc

解决方案

1、vim进入阿里云镜像加速配置文件

vim /etc/docker/daemon.json

2、修改配置文件

完整的配置

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF’
{
“registry-mirrors”: [“https://06wo2xso.mirror.aliyuncs.com”]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

需要删除{}上面两条指令
改为如下即可

{
  "registry-mirrors": ["https://06wo2xso.mirror.aliyuncs.com"]
}
sudo systemctl daemon-reload
sudo systemctl restart docker

3、保存退出，重启即可

[root@javaEE ~]# systemctl start docker
[root@javaEE ~]# docker images
