如何使用docker部署Dashdot工具箱

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

192.168.20.8latestubuntu 22.04

三、检查本地Docker环境

检查本地Docker版本

检查Docker版本：docker version

2. 检查Docker服务状态

检查Docker服务状态，确保Docker服务正常运行。

systemctl status docker
root@WellDone:/home/goodjob/Downloads# systemctl status docker

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
661ff4d9561e: Pull complete

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
