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。
完整创建过程：
1.使用docker-cli启动一个Uptime-Kuma的容器。
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
2.使用docker-compose启动一个Uptime-Kuma的容器
version: "3"
services:
uptime-kuma:
container_name: uptime-kuma
image: louislam/uptime-kuma
ports:
- 9001:3001
volumes:
- /usr/local/uptime-kuma/data:/app/data
- /usr/share/zoneinfo/Asia/Shanghai:/usr/share/zoneinfo/Etc/UTC
restart: always
3.容器启动正常，访问
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
root@WellDone:/home/goodjob# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
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
