【打工日常】使用docker部署轻量的运维监控工具

【打工日常】使用docker部署轻量的运维监控工具

一、Uptime-Kuma介绍

Uptime-Kuma是一个轻量级的自动化运维监控工具,最为引人注目的特点是其出色的监控Dashboard面板。部署简单,工具轻量又强大。而且,Uptime-Kuma是开源免费的,并支持基于Docker的部署方式。它支持网站、容器、数据库等存活检测,并支持通过邮件等方式进行告警,对于有自己的服务器并且提供访问的管理员可以实现告警推送,如果是企业级需要更强大的可以通过zabbix、prometheus、grafana等实现。

二、本次实践介绍

本次实践简介

本次实践部署环境为个人测试环境

本地环境规划

本次实践环境规划:docker快速拉取docker-ui镜像,然后后台启动docker-ui镜像

镜像命名IP地址容器镜像版本操作系统版本
uptime-kumalocalhostlatestubuntu 22.04

创建容器

使用docker快速创建Uptime-Kuma的容器。

  1. 完整创建过程:
  2. 1.使用docker-cli启动一个Uptime-Kuma的容器。
  3. docker run -d --name uptime-kuma -p 9001:3001 -v /usr/local/uptime-kuma/data:/app/data -v /usr/share/zoneinfo/Asia/Shanghai:/usr/share/zoneinfo/Etc/UTC louislam/uptime-kuma:latest
  4. 2.使用docker-compose启动一个Uptime-Kuma的容器
  5. version: "3"
  6. services:
  7. uptime-kuma:
  8. container_name: uptime-kuma
  9. image: louislam/uptime-kuma
  10. ports:
  11. - 9001:3001
  12. volumes:
  13. - /usr/local/uptime-kuma/data:/app/data
  14. - /usr/share/zoneinfo/Asia/Shanghai:/usr/share/zoneinfo/Etc/UTC
  15. restart: always
  16. 3.容器启动正常,访问
  17. http://ip:9001

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

  1. root@WellDone:/home/goodjob# docker ps
  2. CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
  3. uptime-kuma louislam/uptime-kuma "/usr/bin/dumb-init …" uptime-kuma About a minute ago Up About a minute (healthy) 0.0.0.0:9001->3001/tcp, :::9001->3001/tcp

五、访问Uptime-Kuma页面

访问Uptime-Kuma首页 访问地址:http://localhost:9001
