新建容器并启动
# 命令 docker run [参数] [镜像名]# 参数--name="Name" 容器名字，用来区分容器-d 后台运行容器-it 交互运行容器，进入容器操作[root@izbp1g2kp3kgefvmrhy0moz ~]# docker run -it centos[root@b370c8b61809 /]# lsbin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var-p 指定容器端口 ： -p ip:8080-p 主机端口:容器端口-p 容器端口-p ip:主机端口:容器端口-P 随机指定端口
查看正在运行的容器
# 命令 docker ps [参数] #列出当前正在运行的容器#参数-a 列出当前正在运行的容器+历史运行过的-n=?-q 显示运行容器编号-aq 显示所有容器编号
退出容器
exit 直接退出Ctrl + p +q 容器不停止退出
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，须使用rm -f 容器iddocker rm -f $(docker ps -aq) 删除所有容器
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 停止当前运行的容器docker kill 容器id 强制停止当前运行的容器

进入当前正在运行的容器
# 通常容器都是后台运行，我们需要进入容器，进行操作# 方式一# 命令 docker exec -it 容器id /bin/bash[root@izbp1g2kp3kgefvmrhy0moz ~]# docker exec -it 86f21f951e5d /bin/bash[root@86f21f951e5d /]## 方式二# 命令 docker attach 容器id[root@izbp1g2kp3kgefvmrhy0moz ~]# docker attach 86f21f951e5d[root@86f21f951e5d /]#区别：docker exec 进入一个新的终端docker attac 进入正在运行的终端
从容器中拷贝文件
# 命令 docker cp 容器id:容器内路径 目的主机路径[root@izbp1g2kp3kgefvmrhy0moz ~]# docker attach 86f21f951e5d[root@86f21f951e5d home]# ls[root@86f21f951e5d home]# touch wangzheng.py[root@86f21f951e5d home]# lswangzheng.py[root@86f21f951e5d home]# exitexit[root@izbp1g2kp3kgefvmrhy0moz ~]# docker cp 86f21f951e5d:/home/wangzheng.py /home[root@izbp1g2kp3kgefvmrhy0moz ~]# cd /home[root@izbp1g2kp3kgefvmrhy0moz home]# lsadmin wangzheng.py
