我要评论一、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
检查本地docker版本
检查docker版本：docker version root@welldone:/home/goodjob# docker version client: docker engine - community version: 25.0.0 api version: 1.44 go version: go1.21.6 git commit: e758fe5 built: thu jan 18 17:09:49 2024 os/arch: linux/amd64 context: default server: docker engine - community engine: version: 25.0.0 api version: 1.44 (minimum version 1.24) go version: go1.21.6 git commit: 615dfdf built: thu jan 18 17:09:49 2024 os/arch: linux/amd64 experimental: false containerd: version: 1.6.27 gitcommit: a1496014c916f9e62104b33d1bb5bd03b0858e59 runc: version: 1.1.11 gitcommit: v1.1.11-0-g4bccb38 docker-init: version: 0.19.0 gitcommit: 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。
systemctl status docker
root@welldone:/home/goodjob/downloads# systemctl status docker

lines 1-28/28 (end)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 be93293fd536: pull complete 376f9b7a6770: pull complete 4e53c60b2bbe: pull complete 49bb1447e827: pull complete a756fa12f0ae: pull complete 2bf2a9e293f3: pull complete ba77d82c7692: pull complete 4b4fb9a95dae: pull complete 6daae4045e4d: pull complete 3d13531fe87b: pull complete 9c911b84930a: pull complete 7f902ce40bc3: pull complete 12ff3c516952: pull complete digest: sha256:d78f64ccdd92b769794c8ff79d9e27509c4482b8e3d342aa04cd772b3dbd7b74 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
