一、下载及启动：

1、docker 启动

2、docker 删除

ubuntu中docker彻底卸载 - 饭米雪 - 博客园网上很多博主提供的命令行，其实并不能完全卸载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-https://www.cnblogs.com/fmixue/p/15789202.html

二、常见操作：

１image

1.1 获取和列出镜像

# 获取镜像命令格式：docker pull [选项] [Docker Registry 地址[:端口号]/]仓库名[:标签]$ docker pull ubuntu:18.04

1.2 删除和上传镜像

1.3 dockerfile

1.4 image 其他操作

2 container

2.1 查看容器：

docker ps -a
docker container ls

(base) user@ubuntu:~$ docker ps --helpUsage:  docker ps [OPTIONS]List containersOptions:-a, --all             Show all containers (default shows just running)-f, --filter filter   Filter output based on conditions provided--format string   Pretty-print containers using a Go template-n, --last int        Show n last created containers (includes all states) (default -1)-l, --latest          Show the latest created container (includes all states)--no-trunc        Don't truncate output-q, --quiet           Only display container IDs-s, --size            Display total file sizes

2.2 创建及删除容器

(base) user@ubuntu:~$ docker run --helpUsage:  docker run [OPTIONS] IMAGE [COMMAND] [ARG...]Run a command in a new containerOptions:--add-host list                  Add a custom host-to-IP mapping (host:ip)-a, --attach list                    Attach to STDIN, STDOUT or STDERR--blkio-weight uint16            Block IO (relative weight), between 10 and 1000, or 0 to disable (default 0)--blkio-weight-device list       Block IO weight (relative device weight)

2.2.1 常用创建命令

# docker run 命令格式： 
docker run [OPTIONS] IMAGE [COMMAND] [ARG...]$ docker run ubuntu:18.04 /bin/echo 'Hello world'
Hello world$ docker run -t -i ubuntu:18.04 /bin/bash
root@af8bae53bdd3:/## -i 交互使用，-t 显示容器运行终端。常常连在一起使用：-it

2.2.2 启动，终止，重启和删除容器容器


docker container start container_name    # 启动容器docker container stop container_name    # 终止容器docker container restart container_name    # 重启容器docker container rm container_name    # 删除容器# container_name :容器名

2.2.3 进/出容器

docker exec -it container_name docker attach  container_name # 在容器stdin中exit,退出容器后会终止容器# 退出时如果想继续运行：按顺序按【ctrl+p】，【ctrl+q】
# 如果不想继续运行：按【ctrl+d】或输入exit

2.2.4 导出导入容器：（待续ing）

2.2. 5 容器重命名等其他命令

(base) user@ubuntu:~$ docker container --helpUsage:  docker container COMMANDManage containersCommands:attach      Attach local standard input, output, and error streams to a running containercommit      Create a new image from a container's changescp          Copy files/folders between a container and the local filesystemcreate      Create a new containerdiff        Inspect changes to files or directories on a container's filesystemexec        Run a command in a running containerexport      Export a container's filesystem as a tar archiveinspect     Display detailed information on one or more containerskill        Kill one or more running containerslogs        Fetch the logs of a containerls          List containerspause       Pause all processes within one or more containersport        List port mappings or a specific mapping for the containerprune       Remove all stopped containersrename      Rename a containerrestart     Restart one or more containersrm          Remove one or more containersrun         Run a command in a new containerstart       Start one or more stopped containersstats       Display a live stream of container(s) resource usage statisticsstop        Stop one or more running containerstop         Display the running processes of a containerunpause     Unpause all processes within one or more containersupdate      Update configuration of one or more containerswait        Block until one or more containers stop, then print their exit codes
