我是靠谱客的博主怕孤单香氛，最近开发中收集的这篇文章主要介绍Docker 实践指南（一）下载、配置及应用等常见命令一、下载及启动：二、常见操作：，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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 --help

Usage:  docker ps [OPTIONS]

List containers

Options:
  -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 --help

Usage:  docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

Run a command in a new container

Options:
      --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）
