Docker | 离线安装docker

1.准备软件：

docker安装包，下载地址：https://download.docker.com/linux/static/stable/x86_64/

 下载需要的版本到本地，上传到服务器上

2.一键安装命令：install-docker.sh

#!/bin/sh
usage(){
  echo "使用方法: $0 FILE_NAME_DOCKER_CE_TAR_GZ"
  echo "             $0 docker-18.06.3-ce.tgz"
  echo "Get docker-ce binary from: https://download.docker.com/linux/static/stable/x86_64/"
  echo "eg: wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz"
  echo ""
}
SYSTEMDDIR=/usr/lib/systemd/system

if [ $# -ne 1 ]; then
  usage
  exit 1
else
  FILETARGZ="$1"
fi

if [ ! -f ${FILETARGZ} ]; then
  echo "Docker binary tgz files does not exist, please check it"
  echo "Get docker-ce binary from: https://download.docker.com/linux/static/stable/x86_64/"
  echo "eg: wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz"
  exit 1
fi

echo "##unzip : tar xvpf ${FILETARGZ}"
tar xvpf ${FILETARGZ}
echo

echo "##binary : ${DOCKERBIN} copy to ${DOCKERDIR}"
cp -p ${DOCKERBIN}/* ${DOCKERDIR} >/dev/null 2>&1
which ${DOCKERBIN}

echo "##systemd service: ${SERVICEFILE}"
echo "##docker.service: create docker systemd file"

以上文件可以按自己需求进行修改：该文件对应的docker.service文件及daemon.json文件可以修改

3.登录服务器，跳转到压缩包所在文件，创建shell命令文件：

touch install-docker.sh

4.编辑文件：(可以直接用以下命令，vi命令没有文件时会直接创建新文件)

vi install-docker.sh

5.复制上面代码到install-docker.sh，保存退出，给文件赋权限

chmod +x install-docker.sh

6.运行shell命令

./install-docker.sh docker-18.06.1-ce.tgz

 7. 运行完成后查看docker版本：

 如图显示，则dockers安装成功！
