echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null

注：docker镜像加速

• 找到daemon.json，没有就自己创建，具体位置按安装方式自行搜索一下
• 写入内容，如下：

{
    "registry-mirrors": [
        "https://docker.1panel.live",
        "https://docker-0.unsee.tech",
        "https://docker.1panel.live",
        "https://registry.dockermirror.com",
        "https://docker.imgdb.de",
        "https://docker.m.daocloud.io",
        "https://hub.firefly.store",
        "https://hub.littlediary.cn",
        "https://hub.rat.dev",
        "https://dhub.kubesre.xyz",
        "https://cjie.eu.org",
        "https://docker.kejilion.pro",
        "https://docker.1panelproxy.com",
        "https://docker.hlmirror.com",
        "https://hub.fast360.xyz",
