【打工日常】使用docker部署IT运维管理平台CAT-编程知识

一、CAT介绍

CAT是一个专为 IT 运维从业者打造的一站式解决方案平台，包含资产管理、工单、工作流、仓储等功能模块。

本项目是celaraze/chemex重构版，原项目chemex名称弃用；CAT采用全新架构设计，大量提升使用体验的细节，及紧跟最新版；CAT大部分会还原chemex的基础功能，但部分设计可能由于实际业务需求将被弃用；重做了数据导出、导入功能，现在将提供一个更加人性化的方式；简化了部署需求；增加各类资产编号自动生成规则。

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CAT镜像，然后后台启动CAT镜像

镜像命名	IP地址	容器镜像版本	操作系统版本
cat	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
root@WellDone:/home/goodjob#

检查Docker服务状态

检查Docker服务状态，确保Docker服务正常运行。

systemctl status dockerroot@WellDone:/home/goodjob/Downloads# systemctl status docker

四、部署cat镜像

下载cat镜像(为了方便管理，我已传到自己的阿里云镜像)

docker pull registry.cn-guangzhou.aliyuncs.com/welldene/docker:catroot@WellDone:/usr/local/docker-win# docker pull registry.cn-guangzhou.aliyuncs.com/welldene/docker:cat

创建容器

使用docker快速创建cat的容器。

完整创建过程：1.使用docker-cli启动一个cat的容器。docker run -d --name cat --restart always -p 6886:8000 registry.cn-guangzhou.aliyuncs.com/welldene/docker:cat2.使用docker-compose启动一个cat的容器version: '3.9'
services:cat:image: 'registry.cn-guangzhou.aliyuncs.com/welldene/docker:cat'ports:- '6886:8000'restart: alwayscontainer_name: cat3.容器启动正常，访问
http://ip:6886

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
