Docker+jenkins自动化部署SpringCloud微服务项目

著论准过秦，作赋拟子虚。这篇文章主要讲述Docker+jenkins自动化部署SpringCloud微服务项目相关的知识，希望能为你提供帮助。
前言：
随着容器化的不断发展，目前公司也在往容器化部署方面靠拢，这不最近就在整合公司的微服务项目，目标是把传统的微服务改造成Docker环境部署，言归正传，部署流程搞起。
环境准备:

IP	角色
192.168.0.112	Docker环境+jenkins+gitlab+Maven私服
192.168.0.113	Docker环境+Harbor+微服务项目

1. 分别在192.168.0.112,192.168.0.113上面安装Docker

$yum install -y yum-utils $yum-config-manager \\ --add-repo \\ https://download.docker.com/linux/centos/docker-ce.repo $yum -y install docker-ce $docker info#查看docker信息$ vim /etc/docker/daemon.json#配置镜像加速器，提高下载镜像的速度 { "registry-mirrors": ["https://m81hcukn.mirror.aliyuncs.com"] }$ systemctl restart docker

2. 在192.168.0.112上面操作

部署jdk

$tar xf jdk-8u45-linux-x64.tar.gz $mv jdk1.8.0_45/usr/local/jdk8

部署Maven

$tar xf apache-maven-3.5.0-bin.tar.gz $mv apache-maven-3.5.0 /usr/local/maven3#修改Maven源 vim /usr/local/maven3/conf/settings.xml< mirrors> < mirror> < id> central< /id> < mirrorOf> central< /mirrorOf> < name> aliyun maven< /name> < url> https://maven.aliyun.com/repository/public< /url> < /mirror> < /mirrors>

部署Gitlab

docker run -d \\ --name gitlab \\ -p 8443:443 \\ -p 9999:80 \\ -p 9998:22 \\ -v /opt/gitlab/config:/etc/gitlab \\ -v /opt/gitlab/logs:/var/log/gitlab \\ -v /opt/gitlab/data:/var/opt/gitlab \\ -v /etc/localtime:/etc/localtime \\ --restart=always \\ lianzhibo/gitlab-ce-zh:latest

访问地址：http://192.168.0.112:9999 ，初次会先设置管理员密码，然后登陆，默认管理员用户名root，密码就是刚设置的。
创建项目，提交测试代码：

部署Harbor镜像仓库

#安装docker-compose curl -L https://github.com/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose#安装Harbor镜像仓库 harbor-offline-installer-v2.3.2.tgz 下载地址：https://github.com/goharbor/harbor/releases/download/v2.3.2/harbor-offline-installer-v2.3.2.tgz tar zxvf harbor-offline-installer-v2.3.2.tgz cd harbor cp harbor.yml.tmpl harbor.ymlvi harbor.yml hostname: 192.168.0.113 https:# 先注释https相关配置 harbor_admin_password: Harbor12345./prepare#检查配置 ./install.sh #安装

由于habor未配置https，还需要在docker配置可信任

# cat /etc/docker/daemon.json {"registry-mirrors": ["https://m81hcukn.mirror.aliyuncs.com"], "insecure-registries": ["192.168.0.113"] } # systemctl restart docker

部署Jenkins

docker run -d --name jenkins -p 80:8080 -p 50000:50000 -u root\\ -v /opt/jenkins_home:/var/jenkins_home \\ -v /var/run/docker.sock:/var/run/docker.sock\\ -v /usr/bin/docker:/usr/bin/docker \\ -v /usr/local/maven3:/usr/local/maven \\ -v /usr/local/jdk8:/usr/local/jdk \\ -v /etc/localtime:/etc/localtime \\ --restart=always \\ --name jenkins jenkins/jenkins

访问地址：http://192.168.0.112
安装插件：

管理Jenkins-> 系统配置--> 管理插件--> 搜索git ,pipeline，选中点击安装。默认从国外网络下载插件，会比较慢，建议修改国内源：cd /opt/jenkins_home/updates sed -i \'s/http:\\/\\/updates.jenkins-ci.org\\/download/https:\\/\\/mirrors.tuna.tsinghua.edu.cn\\/jenkins/g\' default.json & & \\ sed -i \'s/http:\\/\\/www.google.com/https:\\/\\/www.baidu.com/g\' default.jsondocker restart jenkins

发布测试

New Item -> Pipeline -> This project is parameterized -> String Parameter

Name：Branch # 变量名，下面脚本中调用
Default Value：master # 默认分支
Description：发布的代码分支 # 描述

上述脚本中，docker_registry_auth 和git_auth变量的值为Jenkins凭据ID，添加凭据后修改。
