docker pull centos3.1、新建容器并启动docker run [可选参数] imageName/imageId# 参数说明--name "NAME"容器名字 ， tomcat01, tomcat02, 用来区分容器-d后台方式运行-i, -t#使用交互模式运行，可以进入容器查看内容-p#指定容器端口 -p 8080-p ip:主机端口:容器端口-p 3344:80-p 主机端口:容器端口(常用)-p 容器端口容器端口-P#随机指定端口3.2、启动容器 ， 并进入容器[root@iZm5e----- ~]# docker run -it centos /bin/bash[root@c4a1504a9cf9 /]# ls#查看容器内的centosbindevetchomeliblib64lost+foundmediamntoptprocrootrunsbinsrvsystmpusrvar[root@c4a1504a9cf9 /]# exit # 退出容器exit[root@iZm5e----- ~]#

3.3、查看所有运行的容器docker ps# 查看运行的容器exit之后就停止了容器docker ps -a# 查看所有运行过的以及在运行的容器docker ps -aCONTAINER IDIMAGECOMMANDCREATEDSTATUSPORTSNAMESc4a1504a9cf9centos"/bin/bash"7 minutes agoExited (0) 3 minutes agohungry_eulerdc0c5076048ehello-world"/hello"2 months agoExited (0) 2 months agobusy_coridocker ps -a -n=[数字]# 最近创建的容器docker ps -a -n=1CONTAINER IDIMAGECOMMANDCREATEDSTATUSPORTSNAMESc4a1504a9cf9centos"/bin/bash"11 minutes agoExited (0) 7 minutes agohungry_euler3.4、退出容器exit#容器停止并退出ctrl + p + q#容器不停止退出3.5、删除容器docker rm 容器ID# 删除指定容器不能删除正在运行的容器docker rm -f $(docker ps -aq)# 递归删除所有容器docker ps -a -q|xargs docker rm# 删除所有容器3.6、启动和停止容器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、常用其它命令4.1、后台运行容器docker run -d centos463f1dc43e444ff6b6d0efd3f0c5047e118ddf64deed3aea2a8b5a6c89df61bb[root@iZm5e----- ~]# docker psCONTAINER IDIMAGECOMMANDCREATEDSTATUSPORTSNAMES[root@iZm5e----- ~]#发现后台运行的容器，停止了
docker使用后台运行，就必须要有一个前台进程 。否则，docker发现没有服务 ， 就会自动停止
4.2、查看日志docker logs --help#shell脚本造日志docker run -d centos /bin/sh -c "while true;do echo xiao;sleep 1;done"d5033adf13b49f537430fc19df9fe00b477301dfd3a2d9c287060c65c1a59d7b[root@iZm5e----- ~]# docker psCONTAINER IDIMAGECOMMANDCREATEDSTATUSPORTSNAMESd5033adf13b4centos"/bin/sh -c 'while t…"5 seconds agoUp 4 secondscompetent_jang[root@iZm5e----- ~]# #显示日志docker logs -f -t --tail 10 d5033adf13b42021-09-27T07:05:08.800676670Z xiao2021-09-27T07:05:09.803226803Z xiao2021-09-27T07:05:10.806019019Z xiao2021-09-27T07:05:11.809012200Z xiao2021-09-27T07:05:12.811505073Z xiao2021-09-27T07:05:13.817109532Z xiao2021-09-27T07:05:14.819543508Z xiao2021-09-27T07:05:15.822718210Z xiao...-tf#显示日志--tail [数字]# 显示日志的条数4.3、查看容器中的进程信息 (ps - linux)docker top命令
