一、Dashdot介绍
dashdot是一个简洁清晰的服务器数据仪表板，基于React实现 ，主要是显示操作系统、进程、存储、内存、网络这五个的数据。
二、本次实践介绍
1. 本次实践简介
本次实践部署环境为个人测试环境
2. 本地环境规划
本次实践环境规划：docker快速拉取Dashdot镜像，然后后台启动Dashdot镜像
| 启动镜像后的名字 | IP地址 | 容器镜像版本 | 操作系统版本 |
|---|---|---|---|
| Dashdot | 192.168.20.8 | latest | ubuntu 22.04 |

四、部署Dashdot镜像
1. 下载Dashdot镜像
docker pull mauricenino/dashdot
root@WellDone:/home/goodjob# docker pull mauricenino/dashdot
Using default tag: latest
latest: Pulling from mauricenino/dashdot

Status: Downloaded newer image for mauricenino/dashdot:latest
docker.io/mauricenino/dashdot:latest
2. 创建容器
使用docker快速创建Dashdot的容器。
完整创建过程：
1.启动一个Dashdot的测试容器。
docker run -d -p 2828:3001 --name dashdot -v /etc/os-release:/etc/os-release:ro -v /proc/1/ns/net:/mnt/host_ns_net:ro --privileged mauricenino/dashdot:latest
2.启动完毕后查看下是否启动正常
root@WellDone:/opt# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
811df11cf0f2 mauricenino/dashdot:latest "docker-entrypoint.s..." 2 seconds ago Up 1 second 0.0.0.0:2828->3001/tcp, :::2828->3001/tcp dashdot
3.容器启动正常，访问
http://ip:2828
3. 检查容器运行状态
检查容器的运行状态，确保服务的正常运行。
docker ps
五、访问Dashdot页面
