docker镜像的导入导出

1、安装docker

docker下载地址：https://download.docker.com/linux/static/stable/x86_64
创建文件：vi docker.service

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s

WantedBy=multi-user.target

创建安装脚本：vi install.sh

#!/bin/sh
echo '解压tar包...'
tar -xvf $1
echo '将docker目录移到/usr/bin目录下...'
cp docker/* /usr/bin/
echo '将docker.service 移到/etc/systemd/system/ 目录...'
cp docker.service /etc/systemd/system/
echo '添加文件权限...'
chmod +x /etc/systemd/system/docker.service
echo '重新加载配置文件...'
systemctl daemon-reload
echo '启动docker...'
systemctl start docker
echo '设置开机自启...'
systemctl enable docker.service
echo 'docker安装成功...'

启动docker：systemctl start docker
重启docker：systemctl restart docker
停止docker：systemctl stop docker
启动容器：docker container start CONTAINER ID
关闭容器：docker container stop CONTAINER ID
重启容器：docker container restart CONTAINER ID
删除容器：docker rm CONTAINER ID
列出正在运行的容器：docker ps -a
进入正在运行的容器：docker container exec -it 容器id /bin/bash
传输文件命令：cp /opt/1.txt  CONTAINER ID:/home
