零基础学Docker【2】 | 一文带你快速学习Docker常用命令

前言

本篇是零基础学Docker系列的第二篇文章，在上一篇文章中????​​一文带你快速了解并上手Docker​​已经为大家讲解了一些什么是Docker，如何安装使用Docker的内容，以及对Docker与虚拟机技术的一个简单对比做了一些说明。本篇我们将趁热打铁，需要完成的任务如下：

掌握Docker的常用命令，包含但不限于镜像命令，容器命令，以及一些常用的其他命令学会使用官方文档查找对应的命令说明学会使用帮助命令来查找对应的命令说明

Docker常用命令

​Docker的官方文档非常的详细，关于所有的命令行使用说明/规范，可以参考​ ​​images​​命令为例，可以发现在官方文档上有非常详细的说明，对于每种命令的​介绍说明​，​用法​，​拓展使用​，​参数选项​，​例子​…都非常的齐全。

另外我们也可以通过帮助命令在命令行中让我们了解到不同的命令使用。

1、帮助命令

docker version #显示docker的版本信息。docker info #显示docker的系统信息，包括镜像和容器的数量docker 命令 --help #帮助命令

2、镜像命令

docker images #查看所有本地主机上的镜像 可以使用docker image ls代替docker search #搜索镜像docker pull #下载镜像 docker image pulldocker rmi #删除镜像 docker image rm

​docker images​ 查看所有本地的主机上的镜像

​docker pull​ 下载镜像

能够搜索之后，我们就可以去下载镜像。

# 下载镜像 docker pull 镜像名[:tag][root@localhost ~]# docker pull mysqlUsing default tag: latest #如果不写tag，默认就是latestlatest: Pulling from library/mysql #分层下载： docker image 的核心 联合文件系统 bb79b6b2107f: Pull complete49e22f6fb9f7: Pull complete842b1255668c: Pull complete9f48d1f43000: Pull completec693f0615bce: Pull complete8a621b9dbed2: Pull complete0807d32aef13: Pull completea56aca0feb17: Pull completede9d45fd0f07: Pull complete1d68a49161cc: Pull completed16d318b774e: Pull complete49e112c55976: Pull completeDigest: sha256:8c17271df53ee3b843d6e16d46cff13f22c9c04d6982eb15a9a47bd5c9ac7e2d # 签名防伪 Status: Downloaded newer image for mysql:latestdocker.io/library/mysql:latest #真实地址# 等价于docker pull mysqldocker pull docker.io/library/mysql:latest# 指定版本进行下载[root@localhost ~]# docker pull mysql:5.75.7: Pulling from library/mysqlbb79b6b2107f: Already exists49e22f6fb9f7: Already exists842b1255668c: Already exists9f48d1f43000: Already existsc693f0615bce: Already exists8a621b9dbed2: Already exists0807d32aef13: Already existsf15d42f48bd9: Pull complete098ceecc0c8d: Pull completeb6fead9737bc: Pull complete351d223d3d76: Pull completeDigest: sha256:4d2b34e99c14edb99cdd95ddad4d9aa7ea3f2c4405ff0c3509a29dc40bcb10efStatus: Downloaded newer image for mysql:5.7docker.io/library/mysql:5.7

可以发现存在共用镜像的时候，docker就不会去重复下载，极大的节省了内存。

等待下载完毕，我们再去查看主机上的docker的镜像文件。

可以发现下载的镜像都比较的大，这个时候我们就可以去考虑删除一些镜像。

​docker rmi​ 删除镜像

docker rmi -f 镜像id #删除指定的镜像docker rmi -f 镜像id 镜像id 镜像id # 删除多个镜像docker rmi -f $(docker images -aq) # 骚操作：删除全部的镜像，递归删除[root@localhost ~]# docker rmi -f 1b12f2e9257bUntagged: mysql:5.7Untagged: mysql@sha256:4d2b34e99c14edb99cdd95ddad4d9aa7ea3f2c4405ff0c3509a29dc40bcb10efDeleted: sha256:1b12f2e9257be96da5c075f186dc371b18442b0f9281728ac64c9a69c6e0e264Deleted: sha256:b21d85dcc43f7db4e532c3ca07e5adbc1e02beb37646b7079217ea2b1922af91Deleted: sha256:603c9faa831d58a3f60eb377cd6246a281a97b906406a92bf3452726a6f15b69Deleted: sha256:2d927a6eb4cc26ba5454193a3f4abf503b6cea710293d4f0e6d061c08578b687Deleted: sha256:b96c2c2176ca7b5223469ad39c9e17509505233dd81030878bc12b03074baef4...

3、容器命令

​说明：我们有了镜像，才可以创建容器。接下来，我们将下载一个centos镜像来测试学习。​

[root@localhost ~]# docker pull centosUsing default tag: latestlatest: Pulling from library/centos3c72a8ed6814: Pull completeDigest: sha256:76d24f3ba3317fa945743bb3746fbaf3a0b752f10b10376960de01da70685fbdStatus: Downloaded newer image for centos:latestdocker.io/library/centos:latest

​新建容器并启动​

docker run [可选参数] image # 参数说明--name = “Name” 容器名字 tomcat01 tomcat02，用于区分容器-d 后台方式运行-it 使用交互式运行，进入容器查看内容-p 指定容器的端口 -p 8080:8080 -p ip:主机端口:容器端口 -p 主机端口:容器端口(常用) -p 容器端口 （不加-p，直接加容器端口也可以） -P(大写) 随机指定端口# 测试，启动并进入容器[root@localhost /]# docker run -it centos /bin/bash[root@e1ac54cd636a /]# ls # 查看容器内的centos:基础版本，很多命令都是不完整的！ bin etc lib lost+found mnt proc run srv tmp vardev home lib64 media opt root sbin sys usr# 从容器中退回主机[root@e1ac54cd636a /]# exitexit[root@localhost /]# lsbin dev home lib64 mnt proc run srv tmp varboot etc lib media opt root sbin sys usr

​列出所有运行的容器​

# docker ps 命令 列出当前正在运行的容器 -a ,--all #列出当前正在运行的容器 + 带出历史运行过的容器 -n=?, --last int #列出最近创建的?个容器 ?为1则只列出最近创建的一个容器,为2则列出2个 -q, --quiet #只列出容器的编号 [root@localhost /]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESfd5ea781f128 portainer/portainer "/portainer" 14 hours ago Up 14 hours 0.0.0.0:8088->9000/tcp charming_volhard[root@localhost /]# docker ps -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESe1ac54cd636a centos "/bin/bash" 5 minutes ago Exited (0) 4 minutes ago epic_engelbartfd5ea781f128 portainer/portainer "/portainer" 14 hours ago Up 14 hours 0.0.0.0:8088->9000/tcp charming_volhardec6397ed87c8 bf756fb1ae65 "/hello" 17 hours ago Exited (0) 17 hours ago ecstatic_mestorf1db69ebb5c34 bf756fb1ae65 "/hello" 17 hours ago Exited (0) 17 hours ago eager_lamporta40257529012 bf756fb1ae65 "/hello" 22 hours ago Exited (0) 22 hours ago crazy_greider

​退出容器​

exit # 容器直接退出ctrl +P +Q # 容器不停止退出 -- 注意： 这个是很有用的操作

​删除容器​

docker rm 容器id #删除指定的容器，不能删除正在运行的容器，如果要强制删除 rm -rfdocker rm -f $(docker ps -aq) #删除所有的容器docker ps -a -q|xargs docker rm #删除所有的容器

​启动和停止容器的操作​

docker start 容器id #启动容器docker restart 容器id #重启容器docker stop 容器id #停止当前正在运行的容器docker kill 容器id #强制停止当前容器

4、常用的其他命令

​后台启动容器​

# 命令 docker run -d 镜像名[root@localhost /]# docker run -d centosc792b680e6250ba7c3892de771a7328baa936518cc35cd47eda0634419228dba[root@localhost /]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESfd5ea781f128 portainer/portainer "/portainer" 15 hours ago Up 15 hours 0.0.0.0:8088->9000/tcp charming_volhard# 问题：docker ps：发现 centos 停止了# 常见的坑：docker容器使用后台运行，就必须要有一个前台进程，docker发现没有应用，就会自动停止

​查看日志​

docker logs --helpOptions: --details Show extra details provided to logs * -f, --follow Follow log output --since string Show logs since timestamp (e.g. 2013-01-02T13:23:37) or relative (e.g. 42m for 42 minutes)* --tail string Number of lines to show from the end of the logs (default "all")* -t, --timestamps Show timestamps --until string Show logs before a timestamp (e.g. 2013-01-02T13:23:37) or relative (e.g. 42m for 42 minutes)➜ ~ docker run -d centos /bin/sh -c "while true;do echo 6666;sleep 1;done" #模拟日志 #显示日志-tf #显示日志信息（一直更新）--tail number #需要显示日志条数docker logs -t --tail n 容器id # 查看n行日志docker logs -ft 容器id # 显示所有日志日志# 运行centos 容器[root@localhost /]# docker run -it centos /bin/bash# 查看所有的容器运行情况[root@localhost /]# docker ps -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES529d488fbb4b centos "/bin/bash" 50 seconds ago Up 50 seconds gracious_blackburn4a0ba742b224 centos "/bin/bash" 20 minutes ago Exited (130) 19 minutes ago exciting_perlmanc792b680e625 centos "/bin/bash" 26 minutes ago Exited (0) 26 minutes ago nice_pike# 根据容器id，查询最近的10条日志[root@localhost /]# docker logs -f -t --tail 10 529d488fbb4b#因为我们centos的容器暂时还没有进行任何的操作，所以可能日志显示为空# 我们可以自己编写一段shell脚本[root@localhost /]# docker run -d centos /bin/sh -c "while true;do echo 6666;sleep 1;done"# 再次查看日志[root@localhost /]# docker logs -f -t --tail 10 492b2410a53f2020-11-08T05:54:01.436376750Z 66662020-11-08T05:54:02.438071320Z 66662020-11-08T05:54:03.440787888Z 66662020-11-08T05:54:04.443239744Z 6666...# 就可以观察到有源源不断的日志产生了

​查看容器中进程信息​

​进入当前正在运行的容器​

# 方式一：docker exec -it 容器id bashshell# 测试[root@localhost /]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES9a1f7b30a10a centos "/bin/bash" 16 minutes ago Up 15 minutes jolly_mayer[root@localhost /]# docker exec -it 9a1f7b30a10a /bin/bash[root@9a1f7b30a10a /]# ps -dfUID PID PPID C STIME TTY TIME CMDroot 32 19 0 06:19 pts/1 00:00:00 ps -df[root@9a1f7b30a10a /]# ps -efUID PID PPID C STIME TTY TIME CMDroot 1 0 0 06:03 pts/0 00:00:00 /bin/bashroot 19 0 0 06:18 pts/1 00:00:00 /bin/bashroot 33 19 0 06:19 pts/1 00:00:00 ps -ef# 方式二:docker attach 容器id# 测试[root@localhost /]# docker attach 9a1f7b30a10a正在执行代码....# 命令对比# docker exec # 进入容器后开启一个新的终端，可以在里面操作（常用）# docker attach # 进入容器正在执行的终端，不会启动新的进程

​从容器内拷贝到主机上​

docker cp 容器id:容器内路径 主机目的路径

# 进入正在运行的centos容器内部[root@localhost /]# docker attach 9a1f7b30a10a# 新建一个文件，并退出结束容器[root@9a1f7b30a10a /]# touch test.java[root@9a1f7b30a10a /]# exitexit# 查看此时正运行的容器[root@localhost /]# docker psCONTAINER ID IMAGE COMMAND CREATED S # 查看所有的容器列表 ,只要容器还在,容器内的数据就丢不了 TATUS PORTS NAMES[root@localhost /]# docker ps -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES9a1f7b30a10a centos "/bin/bash" 46 minutes ago # 执行拷贝命令，将容器中的文件拷贝至本机[root@localhost /]# docker cp 9a1f7b30a10a:/test.java /home# 可以在本地查看到从docker容器中拷贝的文件[root@localhost /]# ls /hometest.java

这里讲的拷贝实际上是一个拷贝的过程，未来我们使用 -v 卷的技术，可以实现，容器内与本地文件的自动同步。

小结

Docker的命令实际上非常多，我们最好整理一份命令行大全，今后需要进行查询的话，就可以从中快速获取。
