镜像命令
展示所有的镜像
docker images
[root@iZbp15293q8kgzhur7n6kvZ /]# docker images
# REPOSITORY：镜像仓库
# TAG：标签（版本号），latest 代表最新版
# IMAGE ID：镜像ID，是简化后的
# CREATED：创建时间
# SIZE：镜像大小
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest d2c94e258dcb 10 months ago 13.3kB
参数：
-a：等价于--all，显示所有的镜像，包括中间层镜像
默认情况下，docker images命令只显示顶层镜像，即那些没有被其他镜像所依赖的镜像。而使用-a参数，会显示所有的镜像，包括中间层镜像。中间层镜像是构建镜像过程中生成的临时镜像，它们可能被其他镜像所依赖。
-q：等价于--quiet，只展示镜像的 id
搜索镜像
docker search 镜像名称

删除镜像
docker rmi 镜像名称或镜像ID

容器命令
有镜像才能创建容器，我们这里使用 centos 的镜像来测试
根据镜像创建并运行一个容器
docker run 镜像名称
[root@iZbp15293q8kgzhur7n6kvZ /]# 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:latest
[root@iZbp15293q8kgzhur7n6kvZ /]# docker run centos
# docker run 执行时自带了 docker pull命令
参数：
--name：为容器指定一个名称，不指定则随机一个名字-d：等价于--detach，后台启动容器并打印容器id-i：等价于--interactive，让容器用交互的方式启动-t：等价于--tty，给容器分配一个伪终端，例如/bin/bash-p：等价于--publish，指定端口映射（主机访问的端口:容器端口）-P：大写P，等价于--publish-all，将所有公开的端口发布到随机端口
用交互的方式启动容器，并进入容器内部
docker run -it 镜像名称
[root@iZbp15293q8kgzhur7n6kvZ /]# docker run -it centos
[root@c98e20511eb4 /]# ls
bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
退出容器
# 命令，退出后容器停止运行
exit
# 快捷键，退出后容器不会停止
Ctrl + P + Q
查看正在运行中的容器
docker ps
[root@iZbp15293q8kgzhur7n6kvZ /]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c98e20511eb4 centos "/bin/bash" 2 hours ago Up 2 hours vibrant_rosalind
参数：
-a：等价于--all，显示所有容器，包括已经停止的-q：等价于--quiet，只展示容器ID
容器的启动、重启、停止命令
# 启动一个已经停止的容器
docker start 容器名或容器ID
# 重启一个容器，包括已经停止的容器
docker restart 容器名或容器ID
# 停止一个容器
docker stop 容器名或容器ID
# 强制停止一个容器
docker kill 容器名或容器ID
docker stop和docker kill区别：
docker stop命令会向容器发送一个优雅的停止信号（SIGTERM），让容器有机会进行清理和停止。容器将会接收到该信号并尝试优雅地停止运行中的进程。如果容器在一定时间内没有停止，docker 将会发送一个强制停止信号（SIGKILL）来强制终止容器。这个命令给容器一个正常停止的机会，并且容器可以执行一些清理操作，如保存数据、关闭连接等。
docker kill命令会立即向容器发送一个强制终止信号（SIGKILL），不给容器进行任何清理操作的机会。容器将会立即停止，正在运行的进程将会被强制中断。这个命令是一种强制终止容器的方式，适用于需要立即停止容器的情况。
删除容器
docker rm 容器ID或容器名

以后台方式启动容器，查看正在运行时的容器发现没有刚刚启动的容器，这是因为这个镜像 centos 启动的容器里并没有前台进程，所以刚启动一下子就停止了，如果想查询到这个容器，需要加上-a参数

区别：
exec：docker exec命令用于在正在运行的容器中执行一个新的命令。它会创建一个新的进程，并在容器中执行指定的命令。该命令会在容器的新进程中执行，不会影响容器原有的主进程。使用docker exec可以在容器内部执行命令、进入容器的交互式终端，并且可以在后台运行的容器中执行任务。attach：docker attach命令用于连接到正在运行的容器的标准输入（stdin）、输出（stdout）和错误输出（stderr）。该命令会将你的终端会话附加到容器的主进程上，并将容器的输出直接显示在你的终端上。使用docker attach可以实时查看和参与到容器内部正在运行的进程中，但是当你退出终端会话时，容器将会停止运行。
拷贝容器内的文件到主机上
