【打工日常】使用docker部署轻量的运维监控工具-编程知识

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-kuma	localhost	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 versionroot@WellDone:/home/goodjob# docker version
Client: Docker Engine - CommunityVersion:           25.0.0API version:       1.44Go version:        go1.21.6Git commit:        e758fe5Built:             Thu Jan 18 17:09:49 2024OS/Arch:           linux/amd64Context:           defaultServer: Docker Engine - CommunityEngine:Version:          25.0.0API version:      1.44 (minimum version 1.24)Go version:       go1.21.6Git commit:       615dfdfBuilt:            Thu Jan 18 17:09:49 2024OS/Arch:          linux/amd64Experimental:     falsecontainerd:Version:          1.6.27GitCommit:        a1496014c916f9e62104b33d1bb5bd03b0858e59runc:Version:          1.1.11GitCommit:        v1.1.11-0-g4bccb38docker-init:Version:          0.19.0GitCommit:        de40ad0

检查Docker服务状态

检查Docker服务状态，确保Docker服务正常运行。

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:latest2.使用docker-compose启动一个Uptime-Kuma的容器version: "3"
services:uptime-kuma:container_name: uptime-kumaimage: louislam/uptime-kumaports:- 9001:3001volumes:- /usr/local/uptime-kuma/data:/app/data- /usr/share/zoneinfo/Asia/Shanghai:/usr/share/zoneinfo/Etc/UTCrestart: always3.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
