容器命令
我们有了镜像才能创建容器，linux，下载一个centos镜像来学习
docker pull centos
新建容器并启动
docker run [可选参数] image
# 参数说明
--name=”容器名字“ tomcat01 tomcat02, 用来区分容器
-d 类似于nohup 后台方式运行
-it 使用交互方式运行，进入容器查看内容
-p 指定容器的端口 -p 8080：8080
-p 主机端口：容器端口（常用）
-p 容器端口
-P 随机指定端口
# 测试，运行并进入容器
[root@instance-0mr70vm9 docker]# docker run -it centos /bin/bash
# ”/bin/bash“ 或者 "/bin/sh" 指定控制台命令
[root@6c656ee65606 /]# ls
bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
# 6c656ee65606 主机名是镜像id
# 从容器中退回主机
[root@6c656ee65606 /]# exit
exit
# 查看正在运行的容器
# docker ps 命令
-a # 列出当前正在运行 —— 带出历史运行过的容器
-n=1 # 显示最近创建的1个容器
-q #显示编号
[root@instance-0mr70vm9 docker]# docker ps -a

退出容器
exit # 直接容器停止退出
Ctrl + P + Q #容器不停止退出
删除容器
docker rm 容器ID #不能删除正在运行的容器
docker rm -f $(docker ps -qa) # 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
# 查看容器内存
docker stats
容器和镜像的区别
刚才启动了已经删除了镜像的容器，证明容器是独立于镜像存在的。
容器应该是根据镜像构建出来的一个独立的环境，持久化在硬盘上的

容器和镜像的区别
常用其他命令
后台启动容器
# 命令docker run -d 镜像名
# 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，docker发现没有应用就会自动停止。
# 编写一段shell脚本在容器中运行
[root@instance-0mr70vm9 docker]# docker run -d centos /bin/sh -c "while true;do echo shenbo; sleep 1;done"
