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

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
