docker 日志，元数据以及进程的查看_docker 元数据

大家好，今天我们来分享docker 日志，元数据以及进程的查看

在这之前，我们来讲一次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 ~]#

查看一下正在运行的容器：

发现并没有，因为在后台运行，前台认为没有

这样写，就正常了

所以，docker在后台运行的同时，必须要有一个前台的进程 -it 选项可以解决这个问题

查看docker 日志：

[root@localhost ~]# docker logs      
1

docker日志的帮助文档：

[root@localhost ~]# docker logs  -f -t  --tail 10 39fb3756e692     //查看日志

因为它默认没有东西 ，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 
1

查看docker镜像的元数据（详细详细）

[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
