无法拉取docker 镜像，配置加速器的使用（亲测可用）

方法1.直接获取 Docker Hub 镜像

docker pull docker.m.daocloud.io/library/node:20
docker pull docker.m.daocloud.io/rainbond/rainbond:v5.17.2-release-allinone

方法2.配置镜像加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://docker.m.daocloud.io",
        "https://dockerhub.azk8s.cn",
        "https://mirror.ccs.tencentyun.com",
        "https://dockerproxy.com",
        "https://mirror.baidubce.com",
        "https://docker.mirrors.ustc.edu.cn",

    ]
