前面两篇已经分别介绍了基于docker的JMeter和rancher的一些安装步骤和用法，我们只要按照写的步骤去完成安装是没有问题的，这篇我来继续去说docker的基础知识，现在再看这些命令会更容易记住，也会知道应用场景。

docker run 命令，指定了-i和-t两个命令行参数，-i标志容器中的stdin是开启的，虽然我么目前还没有进入容器中；-t表明分配一个伪中断，-d表明后台运行容器，并返回容器ID；
查看日志：
docker logs 7e7bf911a3a0
查看镜像：
如何查看运行的容器id呢？
docker ps
查看已经创建的容器：
docker ps -a
进入docker容器内部，指定你要进入的id
docker exec -it 7e7bf911a3a0 /bin/bash容器的主机名就是容器的id
[root@JD ~]# docker exec -it 7e7bf911a3a0 /bin/bash
root@7e7bf911a3a0:/# hostname
7e7bf911a3a0
