# 安装部署Docker（二进制包方式）
参考：https://docs.docker.com/engine/install/binaries/
# 1. 先决条件
在尝试从二进制文件安装 Docker 之前，请确保您的主机满足先决条件：
- 当前系统没有安装过docker（如果已安装，请先卸载）
- 必须 64 位安装
- 只适用于Linux或信创操作系统
- Linux内核版本大于等于3.10，建议使用适用于您平台的最新版本的内核。
- iptables1.4 或更高版本
- XZ Utils 4.9 或更高版本
# ubuntu可能默认没有iptables，需要手动安装
sudo apt update -y
sudo apt install iptables
卸载历史安装的docker参考： 注意：卸载前请确认没有使用docker
# ubuntu、debian
apt remove podman containerd docker*
# centos、redhat
yum remove podman containerd docker*
# 2. 安装
Docker数据目录默认安装在 /var/lib/docker ,请注意保证磁盘空间足够，定期检查
# 2.1 下载二进制包
下载地址：https://download.docker.com/linux/static/stable/
请根据cpu选择对应架构（可通过命令arch查看）
进入后建议选择最新版本下载
下载后可上传至服务器/tmp/目录
# 2.2 解压
cd /tmp
tar xzvf docker-27.4.1.tgz
# 再拷贝至 /usr/bin/
# 如果之前有残留文件，提示需要覆盖，直接覆盖即可
cp docker/* /usr/bin/
# 3 配置systemd服务
# 3.1 containerd
mkdir -p /usr/lib/systemd/system/
mkdir -p /etc/containerd
# 生成默认配置文件
containerd config default > /etc/containerd/config.toml
# 创建服务配置文件
cat >/usr/lib/systemd/system/containerd.service << EOF
