docker学习笔记2（狂神）

Docker的常用命令

然后我们来学我们最重要的镜像命令：

docker images 查看所有本地的主机上的镜像

docker search搜索镜像：

docker pull下载镜像：

docker pull 镜像名[:tag]

指定版本下载：

docker rmi删除镜像：

批量删除：

以上命令是针对于镜像

容器命令：

说明：我们有了镜像才可以创建容器，Linux，下载一个centos镜像来测试学习

docker pull centos

新建容器并启动：

测试

启动并进入容器：

这样我们就在docker中去创建了一个linux虚拟机容器。

很多命令是不完善的。

从容器中退回主机：

列出所有运行中的容器：

我们还可以查看我们曾经使用过的容器：

docker ps:列出正在运行的容器

-a:列出正在运行的容器，带出历史运行过的容器

-n=? 显示最近创建的容器

-q:只显示容器的编号

退出容器

exit 容器停止并退出

Ctrl +P+Q 容器不停止退出

删除容器

不加-f不能删除正在运行的容器。

docker ps -a -q|xargs docker rm 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

常用的其它命令

我们现在写完脚本，也能去查到我们的容器，现在我们就可以去查看我们的日志了。

显示日志：

查看全部日志：

查看容器中的进程信息 ps：

top命令

docker top 容器 id

查看镜像的元数据

命令：docker inspect d0ce277cd508
