大家好，今天我们来分享一下。docker 查看日志、元数据和过程
在此之前，让我们一次又一次地谈谈docker其它的命令
启动容器并在后台运行
[root@localhost ~]# docker run -d centos /bin/bash 76a165f7d1a8469fe3de519c3eb5a1dd5fe1af759ecdbee6c69b82a756379972 [root@localhost ~]# 检查正在运行的容器：
没有发现，因为在后台运行，前台认为没有
这样写是正常的 所以，docker在后台运行时，必须有前台的过程 -it 选项可以解决这个问题
查看docker 日志：
[root@localhost ~]# docker logs docker日志帮助文件：
[root@localhost ~]# docker logs -f -t --tail 10 39fb3756e692 ///查看日志 因为它默认什么都没有 ，所以我们写个shell 脚本
[root@localhost ~]# docker run -d centos /bin/sh -c "while true:do echo shuaige :sleep 1;done" 查看docker 进程
docker top 查看docker镜像元数据(详细)
[root@localhost ~]# docker inspect 39fb3756e692

它的创建时间
这是镜像的来源：
这是挂载，目前还没有做
这是它的环境配置
这是它的cmd 命令
这是这个镜像的网络信息 好了，有关于docker 日志，元数据以及进程的查看，就到这里了，谢谢大家
