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

三、检查本地Docker环境

1. 检查本地Docker版本

检查Docker版本：docker versionroot@WellDone:/home/goodjob# docker version
Client: Docker Engine - CommunityVersion:           25.0.0API version:       1.44Go version:        go1.21.6Git commit:        e758fe5Built:             Thu Jan 18 17:09:49 2024OS/Arch:           linux/amd64Context:           defaultServer: Docker Engine - CommunityEngine:Version:          25.0.0API version:      1.44 (minimum version 1.24)Go version:       go1.21.6Git commit:       615dfdfBuilt:            Thu Jan 18 17:09:49 2024OS/Arch:          linux/amd64Experimental:     falsecontainerd:Version:          1.6.27GitCommit:        a1496014c916f9e62104b33d1bb5bd03b0858e59runc:Version:          1.1.11GitCommit:        v1.1.11-0-g4bccb38docker-init:Version:          0.19.0GitCommit:        de40ad0
root@WellDone:/home/goodjob# 

 2. 检查Docker服务状态

检查Docker服务状态，确保Docker服务正常运行。

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:latest2.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   dashdot3.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
