使用docker create [image-name] 创建一个容器
创建一个nginx镜像的容器，由于没有指定各项参数，容器实用默认参数，创建后并不会启动，并将容器的ID输出到终端，如果本地没有镜像，将从网络下载镜像。[root@docker ~]# docker create nginx 63dd9de3c7280959175223c32253623ac0c0ec7680f1051391b62adc126d464f
使用docker run [image-name] 创建一个容器并运行该容器
创建一个nginx镜像的容器，由于没有指定各项参数，容器实用默认参数，创建并启动运行，并将容器的ID输出到终端，如果本地没有镜像，将从网络下载镜像。但是请使用-d 参数，让容器运行在后台，不然该终端将会被占用无法使用。[root@docker ~]# docker run -d nginx 593d0b66c5b44b2b810076469872d1032376116e2352846aa60a190f7365d914
实用docker ps -a 命令查看当前docker创建的容器，并显示运行状态
[root@docker ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 63dd9de3c728 nginx "nginx -g 'daemon ..." 3 minutes ago Created gifted_minsky
启动一个创建好的或者被停止的容器
使用docker start [container id] 启动容器[root@docker ~]# docker start 63dd9de3c728 63dd9de3c728 [root@docker ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 63dd9de3c728 nginx "nginx -g 'daemon ..." 7 minutes ago Up 4 seconds 80/tcp gifted_minsky
停止一个正在运行的容器
使用docker stop [container id] 启动容器[root@docker ~]# docker stop 63dd9de3c728 63dd9de3c728 [root@docker ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 63dd9de3c728 nginx "nginx -g 'daemon ..." 9 minutes ago Exited (0) 4 seconds ago gifted_minsky
使用docker rm 删除一个容器
如果被删除的容器处于运行状态，将无法删除[root@docker ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 63dd9de3c728 nginx "nginx -g 'daemon ..." 11 minutes ago Up 2 seconds 80/tcp gifted_minsky [root@docker ~]# docker rm 63dd9de3c728 Error response from daemon: You cannot remove a running container 63dd9de3c7280959175223c32253623ac0c0ec7680f1051391b62adc126d464f. Stop the container before attempting removal or force remove
停止要删除后的容器然后在删除容器
[root@docker ~]# docker stop 63dd9de3c728 63dd9de3c728 [root@docker ~]# docker rm 63dd9de3c728 63dd9de3c728 [root@docker ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
创建容器的参数
| OPTIONS | 说明 |
|---|---|
| -a stdin | 指定标准输入输出内容类型，可选 STDIN/STDOUT/STDERR 三项 |
| -d | 后台运行容器，并返回容器ID |
| -i | 以交互模式运行容器，通常与 -t 同时使用 |
| -t | 为容器重新分配一个伪输入终端，通常与 -i 同时使用 |
| --name="nginx-lb" | 为容器指定一个名称 |
| --dns 8.8.8.8 | 指定容器使用的DNS服务器，默认和宿主一致 |
| --dns-search example.com | 指定容器DNS搜索域名，默认和宿主一致 |
| -h "mars" | 指定容器的hostname |
| -e username="ritchie" | 设置环境变量 |
| --env-file=[] | 从指定文件读入环境变量 |
| --cpuset="0-2" or --cpuset="0,1,2" | 绑定容器到指定CPU运行 |
| -m | 设置容器使用内存最大值 |
| --net="bridge" | 指定容器的网络连接类型，支持 bridge/host/none/container: 四种类型 |
| --link=[] | 添加链接到另一个容器 |
| --expose=[] | 开放一个端口或一组端口 |
-it
-it 参数一般连用，在docker run 启动一个容器后提供一个容器的终端，如果容器中没开启shell进程，也无法对容器进行交互[root@docker ~]# docker run -it centos [root@a8c4541d52fc /]#
退出容器请使用CTRL + D ；CTRL + C 只会发送给容器的shell，不会退出容器
--name="container name"
--name 将会为容器指定一个名称，没有这个参数，容器的名称将由系统分配[root@docker ~]# docker create --name="centos-1" centos eb96e184b3840979de8c9e66adda190c8465fc73dfae65418d8bc0c9c62f491c [root@docker ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES eb96e184b384 centos "/bin/bash" 25 seconds ago Created centos-1
-p
-p 参数将一个docker主机的端口映射到容器中，有如下几种格式：ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | [range hostPort]:containerPort |[range hostPort]:[range containerPort]
[root@docker ~]# docker run -it -d -p 192.168.0.141:10000:80 --name=c-1 centos 37a154d52dc218499e535e2264753006dc29e40e7d33f35be420d38b3bfb4847 [root@docker ~]# docker run -it -d -p 192.168.0.141::80 --name=n-1 centos 1acf8de94a8e485a19be3e5be0735f4e88807cee8c0f466d18eb1bf2c633ab44 [root@docker ~]# docker run -it -d -p 10001:80 --name=a-1 centos bbb33f76794dd059a96872c1ff2add28719df15b326fb87864284d10d5e9d470 [root@docker ~]# docker run -it -d -p 10010-10020:80-90 --name=q-1 centos 3877df081cea0903ba91910bf4ee5150cac55d337435f66075c237956350bd42 [root@docker ~]# docker run -it -d -p 10030-10040:80 --name=w-1 centos 8296c4196bfaae55d7d7ec145086bf31b257aea733567501a61d57dcd553a320 [root@docker ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8296c4196bfa centos "/bin/bash" 3 seconds ago Up 2 seconds 0.0.0.0:10031->80/tcp w-1 3877df081cea centos "/bin/bash" 11 seconds ago Up 10 seconds 0.0.0.0:10010->80/tcp, 0.0.0.0:10011->81/tcp, 0.0.0.0:10012->82/tcp, 0.0.0.0:10013->83/tcp, 0.0.0.0:10014->84/tcp, 0.0.0.0:10015->85/tcp, 0.0.0.0:10016->86/tcp, 0.0.0.0:10017->87/tcp, 0.0.0.0:10018->88/tcp, 0.0.0.0:10019->89/tcp, 0.0.0.0:10020->90/tcp q-1 bbb33f76794d centos "/bin/bash" 19 seconds ago Up 18 seconds 0.0.0.0:10001->80/tcp a-1 1acf8de94a8e centos "/bin/bash" 27 seconds ago Up 26 seconds 192.168.0.141:32769->80/tcp n-1 37a154d52dc2 centos "/bin/bash" 39 seconds ago Up 39 seconds 192.168.0.141:10000->80/tcp c-1
-v 挂载数据卷
将本地文件/root/pan1/pan.txt 挂载到容器/etc/resolv.conf[root@docker ~]# docker run -d --name web-1 -v /root/pan1/pan.txt:/etc/resolv.conf nginx d01e19d1c6284a7a5dfc344c7f4ee27da5c099d7ebd95048efea3e6c7b038d55
将本地目录/root/pan1挂载到容器/etc/pan1 下
[root@docker ~]# docker run -d --name web-2 -v /root/pan1:/etc/pan1 nginx 52a1a7df2964e62a11cf53778e3d461e21090857b03d277db36509c94b3be660
创建一个数据卷，数据卷不会随着容器被删除而被删除
[root@docker ~]# docker create -v /shiyanloudata --name shiyan -it centos 46fa93471dda1814781ba57727e12e7678ca243b281ed928b64752ab6b2f6031 [root@docker ~]# docker volume ls DRIVER VOLUME NAME local f8bb990062eebe25d7fdfaa76db5130d89ebacd50a18e25992e83e97ba862123
数据卷可以被多个容器共享，容器挂载其他容器的数据卷
[root@docker ~]# docker run --volumes-from shiyan --name web12345 -d nginx 8b6cb7beed18e2070fea14b00db89c7b1b7491ed40f1850cef9e5e83c9859103
