安装 Docker (Linux)

Docker 需要前置安装 iptables

yq -V > /dev/null 2>&1 || (echo "yq 未安装，请先安装 yq" && exit 1)

# VERSION=27.0.3  # 在 https://download.docker.com/linux/static/stable/x86_64/ 中，选择一个 Docker 的版本
# wget https://download.docker.com/linux/static/stable/$(uname -m)/docker-$VERSION.tgz
# tar xf docker-$VERSION.tgz

TAR="$(curl https://download.docker.com/linux/static/stable/x86_64/ 2&>1 | grep docker | grep -v rootless | tail -n 1 | awk -F'"' '{print $2}')"
wget "https://download.docker.com/linux/static/stable/$(uname -m)/$TAR"
tar xf "$TAR"
