yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

docker-compose --version

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF‘
{
  "registry-mirrors": ["https://yasrs3t5.mirror.aliyuncs.com"],
  "insecure-registries": ["192.168.1.152"]
}
EOF

systemctl daemon-reload
systemctl restart docker
