1 从安装和删除语句说起
1 docker引擎安装语句
sudo apt-get install docker-ce docker-ce-cli containerd.io
2 docker引擎删除语句
sudo apt-get remove docker docker-engine docker.io containerd runc
那么什么是 docker-ce docker-ce-cli containerd.io ？
2 Docker引擎：启动-停止-查看
1 要如何启动docker引擎？
systemctl start docker 或 sudo systemctl restart docker
2 要如何关闭docker引擎？
systemctl stop docker
3 如何查看docker引擎？
systemctl status docker
3 关于docker-hub：查看-拉取-登录
1 查看码头上各个公有仓库的镜象docker search nvidia ；查看带nvidia的镜像
docker search opencv ；查看带opencv的镜像
2 拉取（下载）镜像
docker pull name-image ；从仓库查到的镜像名称
3 进入自己的私有仓库（在docker-hub上）
docker registry
4 关于Images：的镜像操作（抽取、查看、实例化）
（一）产生和消灭images：
1 从hub上拉取镜像
docker pull name-image
2 删除本地镜像
docker rmi id（镜像的标识）3 创造本地镜像
docker build -t new_image_name:tag
（二） 查看本地镜像
docker images
（三）从镜像生成容器
docker run xxxxxxxxx语句
docker run -d
docker run -d -p 5672:5672 -p 15672:15672 --name rabbitmq 80bd4b95a49d（四）镜像和本地文件转化
4. 镜像的导入导出(不规范)
# 将本地的镜像导出
docker save -o 导出的路径 镜像id
# 加载本地的镜像文件
docker load -i 镜像文件
# 修改镜像名称
docker tag 镜像id 新镜像名称:版本附录：docker命令集合
Usage: docker [OPTIONS] COMMAND
A self-sufficient runtime for containers
Options:
--config string Location of client config files (default "/home/huatec/.docker")
-c, --context string Name of the context to use to connect to the daemon (overrides

-D, --debug Enable debug mode
-H, --host list Daemon socket(s) to connect to
-l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default
"info")
--tls Use TLS; implied by --tlsverify
--tlscacert string Trust certs signed only by this CA (default "/home/huatec/.docker/ca.pem")
--tlscert string Path to TLS certificate file (default "/home/huatec/.docker/cert.pem")
--tlskey string Path to TLS key file (default "/home/huatec/.docker/key.pem")
--tlsverify Use TLS and verify the remote
-v, --version Print version information and quit
