Ubbuntu docker-ce 的卸载和安装

卸载docker

# 删除某软件,及其安装时自动安装的所有包
sudo apt-get autoremove docker docker-ce docker-engine  docker.io  containerd runc;

# 删除无用的相关的配置文件
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P ;

#卸载没有删除的docker相关插件(结合自己电脑的实际情况)
sudo apt-get autoremove docker-ce-*;

#删除docker的相关配置&目录
 sudo rm -rf /etc/systemd/system/docker.service.d;
 sudo rm -rf /var/lib/docker;

#确定docker卸载完毕
docker --version;

安装docker

1.下载想要的docker-ce

传送门

2. 复制脚本文件

#!/bin/sh

usage(){
  echo "Usage: $0 FILE_NAME_DOCKER_CE_TAR_GZ"
  echo "       $0 docker-17.09.0-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-17.09.0-ce.tgz"
  echo ""
}
SYSTEMDDIR=/lib/systemd/system
SERVICEFILE=docker.service
DOCKERDIR=/usr/bin
DOCKERBIN=docker
SERVICENAME=docker

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-17.09.0-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: ${SERVICEFILE}"
echo "##docker.service: create docker systemd file"
cat >${SYSTEMDDIR}/${SERVICEFILE} <<EOF

groupadd docker;

gpasswd -a $USER docker;

newgrp docker;

docker ps;

3. 给脚本添加可执行权限

chmod +x 脚本文件

4. 运行脚本和下载的docker-ce

sudo ./脚本文件  docker-ce文件名
