此处示例 Docker 二进制文件目录为
/opt/docker/bin、Docker 数据目录为/opt/docker/data，实际请按需修改
mkdir -pv /opt/docker/{bin,data}
mkdir -pv /etc/docker
groupadd -r -g 1001 docker
useradd -r -g docker -u 1001 -d /home/docker -s /bin/bash docker
modprobe br_netfilter
echo 'net.bridge.bridge-nf-call-ip6tables = 1' > /etc/sysctl.d/docker.conf
echo 'net.bridge.bridge-nf-call-iptables = 1' >> /etc/sysctl.d/docker.conf
echo 'net.ipv4.ip_forward = 1' >> /etc/sysctl.d/docker.conf
sysctl --system
下载地址：
示例如下：
wget https://download.docker.com/linux/static/stable/x86_64/docker-27.0.3.tgz
解压上一步中下载的二进制包到自定义目录（此处将文件解压到 /opt/docker/bin 目录）
tar zxvf docker-27.0.3.tgz -C /opt/docker/bin --strip-components 1
解压后文件夹中包含的文件如下：
