云原生之使用Docker部署Dashdot服务器仪表盘

一、Dashdot介绍

Dashdot是一款简单、实用的开源服务器仪表盘，设计时考虑到了玻璃形态。它旨在用于较小的 VPS 和私人服务器。

二、检查本地系统环境

1.检查本地系统版本

[root@jeven ~]# cat /etc/os-release 
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

2.检查docker状态

[root@jeven ~]# systemctl status docker

3.检查docker版本

[root@jeven ~]# docker -v
Docker version 20.10.17,build 100c701

三、下载Dashdot镜像

[root@jeven ~]# docker pull mauricenino/dashdot
Using default tag: latest
latest: Pulling from mauricenino/dashdot
ca7dd9ec2225: Already exists 
55371e6747e8: Pull complete

Status: Downloaded newer image for mauricenino/dashdot:latest
docker.io/mauricenino/dashdot:latest

四、部署Dashdot应用

1.创建安装目录

mkdir -p /data/dashdot

2.创建Dashdot容器

docker  run  -d  \
  -p 8987:3001 \
  -v /etc/os-release:/etc/os-release:ro \
  -v /proc/1/ns/net:/mnt/host_ns_net:ro \
  --privileged \
  mauricenino/dashdot

3.查看Dashdot容器状态

[root@jeven dashdot]# docker ps
CONTAINER ID   IMAGE                                   COMMAND                  CREATED         STATUS         PORTS                                                                                                                 NAMES
71e9dedb50f2   mauricenino/dashdot                     "docker-entrypoint.s…"   4 seconds ago   Up 2 seconds   0.0.0.0:8987->3001/tcp,:::8987->3001/tcp                                                                             lucid_williams

五、访问Dashdot
