Centos7以及WSL1804 安裝Docker 配置阿里源鏡像加速

Centos7

# step 1: 安裝必要的一些系統工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加軟件源信息 阿里鏡像（國外連不上）
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3: 更新並安裝 Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["********************"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
