一.从镜像启动一个容器
1>.前台启动容器
[root@docker201.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest c7460dfcab50 4 days ago 126MB alpine latest cc0abc535e36 2 weeks ago 5.59MB [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:22 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::* [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker run nginx
2>.后台启动容器
[root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 99b6a121adae nginx "nginx -g 'daemon of…" 3 minutes ago Exited (0) 17 seconds ago zealous_khorana [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker run -d nginx fb899a454b58342af808dd4b446e53696d5e1f69b7dcaf414f4467a041ac88a7 [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES fb899a454b58 nginx "nginx -g 'daemon of…" 3 seconds ago Up 2 seconds 80/tcp inspiring_morse 99b6a121adae nginx "nginx -g 'daemon of…" 4 minutes ago Exited (0) 42 seconds ago zealous_khorana [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES fb899a454b58 nginx "nginx -g 'daemon of…" 8 seconds ago Up 7 seconds 80/tcp inspiring_morse [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]#
3>.创建容器时并进入容器（依赖于"-i"(保持一个标准输入)和"-t"(分配一个tty终端)两个参数）
[root@docker201.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest c7460dfcab50 4 days ago 126MB alpine latest cc0abc535e36 2 weeks ago 5.59MB [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker run -it nginx bash root@b348fb4b1c0a:/# root@b348fb4b1c0a:/# cat /etc/issue Debian GNU/Linux 10 l root@b348fb4b1c0a:/# root@b348fb4b1c0a:/# uname -a Linux b348fb4b1c0a 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 GNU/Linux root@b348fb4b1c0a:/# root@b348fb4b1c0a:/# exit exit [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# uname -a Linux docker201.yinzhengjie.org.cn 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]#
4>.自定义容器名称(一般在单机上会有点作用，在k8s集群中咱们很少去自定义容器名称哟~)
[root@docker201.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest c7460dfcab50 4 days ago 126MB alpine latest cc0abc535e36 2 weeks ago 5.59MB [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker run --name mynginx -d nginx a5e8c6f610f935fdbadf26d6278d477d71b83ca1890e78790299e5490ed6773a [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a5e8c6f610f9 nginx "nginx -g 'daemon of…" 3 seconds ago Up 2 seconds 80/tcp mynginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]#
5>.单次运行容器(容器退出后会自动删除,主要用于临时验证镜像内容的是否符合咱们的标准，如配置文件目录组织结构等信息)
6>.启动容器时指定DNS服务器地址及主机名等
[root@docker201.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest c7460dfcab50 4 days ago 126MB alpine latest cc0abc535e36 2 weeks ago 5.59MB [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a5e8c6f610f9 nginx "nginx -g 'daemon of…" 18 minutes ago Up 18 minutes 80/tcp mynginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker run -it --rm --name mynginx-test --hostname yinzhengjieDocker --dns 219.141.136.10 --dns 219.141.140.10 nginx bash root@yinzhengjieDocker:/# root@yinzhengjieDocker:/# cat /etc/resolv.conf search yinzhengjie.org.cn nameserver 219.141.136.10 nameserver 219.141.140.10 root@yinzhengjieDocker:/# root@yinzhengjieDocker:/#
7>.创建容器时传递运行参数(容器需要有一个前台运行的进程才能保容器的运行，通过传递运行参数是一种方式，另外也可以在构建镜像的时候指定容器启动时在前台的运行命令)
[root@docker201.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest c7460dfcab50 4 days ago 126MB alpine latest cc0abc535e36 2 weeks ago 5.59MB [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# which tail /usr/bin/tail [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker run -d --name myNginx nginx /usr/bin/tail -f "/etc/hosts" fa701fc927e743ff44556fe4a12700fe180b399c2e6903d76a68a04613944c78 [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES fa701fc927e7 nginx "/usr/bin/tail -f /e…" 4 seconds ago Up 3 seconds 80/tcp myNginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]#

2>.获取容器的IP地址
[root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 73fe91c5c64d nginx "bash" 8 minutes ago Up 8 minutes 80/tcp myNginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container inspect -f "{{.NetworkSettings.IPAddress}}" 73fe91c5c64d #可以指定容器的ID 172.17.0.2 [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container inspect -f "{{.NetworkSettings.IPAddress}}" myNginx #也可以指定容器的名称 172.17.0.2 [root@docker201.yinzhengjie.org.cn ~]#
3>.获取容器的PID信息
[root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 73fe91c5c64d nginx "bash" 8 minutes ago Up 8 minutes 80/tcp myNginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container inspect -f "{{.State.Pid}}" 73fe91c5c64d 36347 [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container inspect -f "{{.State.Pid}}" myNginx 36347 [root@docker201.yinzhengjie.org.cn ~]#
六.进入到正在运行的容器
1>.使用attach命令连接正在运行的容器(生产环境中不推荐使用，因为使用exit退出后容器会跟着自动关闭)
[root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES c212441f89c4 nginx "bash" 3 seconds ago Up 2 seconds 80/tcp myNginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container attach c212441f89c4 root@c212441f89c4:/# root@c212441f89c4:/# ls / bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var root@c212441f89c4:/# root@c212441f89c4:/# date Tue Jan 14 15:53:02 UTC 2020 root@c212441f89c4:/# root@c212441f89c4:/# date +%Y-%m-%d-%H:%M:%S 2020-01-14-15:55:05 root@c212441f89c4:/# root@c212441f89c4:/# exit exit [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES c212441f89c4 nginx "bash" 3 minutes ago Exited (0) 3 seconds ago myNginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]#
2>.使用exec命令(生产环境推荐使用这种方式)
[root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 73fe91c5c64d nginx "bash" 4 seconds ago Up 4 seconds 80/tcp myNginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container exec -it myNginx bash root@73fe91c5c64d:/# root@73fe91c5c64d:/# cat /etc/hosts 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 172.17.0.2 73fe91c5c64d root@73fe91c5c64d:/# root@73fe91c5c64d:/# exit exit [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 73fe91c5c64d nginx "bash" 43 seconds ago Up 42 seconds 80/tcp myNginx [root@docker201.yinzhengjie.org.cn ~]# [root@docker201.yinzhengjie.org.cn ~]#
