1、基本容器命令
说明：有了镜像才可以创建容器。
实验前准备：下载一个最新的centos的镜像，当前最新的是centos8.x
[root@localhost ~]# docker pull centos
Using default tag: latest
latest: Pulling from library/centos
a1d0c7532777: Pull complete
Digest: sha256:a27fd8080b517143cbbbab9dfb7c8571c40d67d534bbdee55bd6c473f432b177
Status: Downloaded newer image for centos:latest
docker.io/library/centos:latest1.1、docker run #启动镜像
（1）常用参数说明
--name #为容器分配一个名称
--detach，-d #在后台运行容器并打印容器ID
--interactive，-i #即使未连接STDIN，也应使其保持打开状态， #-it 使用交互方式运行，进入容器查看内容
--tty，-t #分配伪TTY
--publish，-p #将容器的端口发布到主机，指定容器端口（小p）
-p #ip：主机端口：容器端口
-p #主机端口：容器端口（常用）
-p #容器端口
--publish-all，-P #将所有公开的端口发布到随机端口，随机指定端口（大P）（2）使用交互方式进入容器，并退出
[root@localhost ~]# docker run -it centos /bin/bash #使用bash命令
[root@0fdfd540855e /]# ls #查看容器内的centos，基础版本，很多命令不完善
bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
[root@0fdfd540855e /]# pwd
/
[root@0fdfd540855e /]# exit #停止运行并退出，使用快捷键ctrl+p+q，容器运行并退出
exit1.2、docker ps #显示所有正在运行的容器
（1）常用参数
-a #列出当前正在运行的容器+历史运行的容器
-n=？ #显示最近创建的容器，后面跟个数
-q #只显示容器的编号（2）操作示例
[root@localhost ~]# docker ps

docker rm 容器ID #删除指定容器，不能删除正在运行的容器，强制删除加-f参数
docker rm -f $(docker ps -qa) #删除所有容器
docker ps -a -q|xargs docker rm #删除所有容器1.4、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 #停止容器
docker kill 容器ID #强制停止当前容器
[root@localhost ~]# docker ps #查看正在运行的容器，当下有一个正在运行的容器

[root@localhost ~]# docker kill 6fa211a6ad77 #杀掉正在运行编号为6fa211a6ad77的容器
6fa211a6ad771.5、后台启动容器
# 命令 docker run -d 镜像名
[root@kuangshen /]# docker run -d centos
# 问题docker ps，发现 centos 停止了
# 常见的坑:docker 容器使用后台运行，就必须要有要一个前台进程，doker发现没有应用，就会自动停止
# nginx，容器启动后，发现自己没有提供服务，就会立刻停止，就是没有程序了1.6、查看日志
docker logs -tf --tail {number} 容器ID或名称
# 编写一段脚本测试日志
[root@localhost ~]# docker run -d centos /bin/bash -c "while true;do echo 1111111;sleep 1;done" #一直重复打印10
