基于Docker容器DevOps应用方案 企业业务代码发布系统

一、企业业务代码发布方式

1.1 传统方式

• 以物理机或虚拟机为颗粒度部署
• 部署环境比较复杂，需要有先进的自动化运维手段
• 出现问题后重新部署成本大，一般采用集群方式部署
• 部署后以静态方式展现

1.2 容器化方式

• 以容器为颗粒度部署
• 部署方式简单，启动速度快
• 一次构建可到处运行
• 出现故障后，可随时恢复
• 可同时部署多套环境（测试、预发布、生产环境等）

二、企业业务代码发布逻辑图

三、企业业务代码发布工具及流程图

3.1 工具

序号	工具	工具用途
1	git	用于提交业务代码或克隆业务代码仓库
2	gitlab	用于存储业务代码
3	jenkins	用于利用插件完成业务代码编译、构建、推送至Harbor容器镜像仓库及项目部署
4	tomcat	用于运行JAVA业务代码
5	maven	用于编译业务代码
6	harbor	用于存储业务代码构建的容器镜像存储
7	docker	用于构建容器镜像，部署项目

3.2 流程图

本次部署Java代码包。

四、企业业务代码发布系统环境部署

4.1 主机规划

序号	主机名	主机IP	主机功能	软件
1	dev	192.168.10.20	开发者 项目代码 solo	git
2	gitlab-server	192.168.10.21	代码仓库	gitlab-ce
3	jenkins-server	192.168.10.22	编译代码、打包镜像、项目发布	jenkins、docker、git
4	harbor-server	192.168.10.23	存储容器镜像	harbor、docker
5	web-server	192.168.10.24	运行容器，项目上线	docker

5.5 构建项目运行基础应用容器镜像

在harbor-server主机上操作

5.5.1 创建项目目录

[root@harbor-server ~]# mkdir tomcatdir
[root@harbor-server ~]# cd tomcatdir

5.5.2 生成Dockerfile文件

[root@harbor-server tomcatdir]# echo "tomcat is running" >> index.html

[root@harbor-server tomcatdir]# vim Dockerfile
[root@harbor-server tomcatdir]# cat Dockerfile
FROM centos:centos7

MAINTAINER "www.kubemsb.com"

ENV VERSION=8.5.75
ENV JAVA_HOME=/usr/local/jdk
ENV TOMCAT_HOME=/usr/local/tomcat

RUN yum -y install wget

RUN wget https://dlcdn.apache.org/tomcat/tomcat-8/v${VERSION}/bin/apache-tomcat-${VERSION}.tar.gz --no-check-certificate

RUN tar xf apache-tomcat-${VERSION}.tar.gz

RUN mv apache-tomcat-${VERSION} /usr/local/tomcat

RUN rm -rf apache-tomcat-${VERSION}.tar.gz /usr/local/tomcat/webapps/*

RUN mkdir /usr/local/tomcat/webapps/ROOT

ADD ./index.html /usr/local/tomcat/webapps/ROOT/

ADD ./jdk /usr/local/jdk


RUN echo "export TOMCAT_HOME=/usr/local/tomcat" >> /etc/profile

RUN echo "export JAVA_HOME=/usr/local/jdk" >> /etc/profile

RUN echo "export PATH=${TOMCAT_HOME}/bin:${JAVA_HOME}/bin:$PATH" >> /etc/profile

RUN echo "export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar" >> /etc/profile


RUN source /etc/profile

EXPOSE 8080

CMD ["/usr/local/tomcat/bin/catalina.sh","run"]

[root@harbor-server tomcatdir]# ls
Dockerfile  index.html  jdk

5.5.3 使用docker build构建容器镜像

[root@harbor-server tomcatdir]# docker build -t 192.168.10.23/library/tomcat:8575 .

5.5.4 推送容器镜像至harbor容器镜像仓库

[root@harbor-server tomcatdir]# docker images
REPOSITORY                      TAG       IMAGE ID       CREATED              SIZE

Login Succeeded

[root@harbor-server tomcatdir]# docker push 192.168.10.23/library/tomcat:8575

5.5.5 验证容器镜像可用性

[root@harbor-server ~]# docker run -d 192.168.10.23/library/tomcat:8575
d5443961ca65311ca0d68d53d44be997f5d6fde2d78772173ac6927112f34579

[root@harbor-server ~]# docker ps
CONTAINER ID   IMAGE                                COMMAND                  CREATED         STATUS                 PORTS                                   NAMES

[root@harbor-server ~]# docker inspect d544

获得：172.17.0.2

[root@harbor-server ~]# curl http://172.17.0.2:8080
tomcat is running

5.6 项目构建及发布

5.6.1 项目构建及发布步骤

第一步：jenkins获取项目代码

第二步：jenkins对项目代码编译，由maven完成

第三步：jenkins使用docker对编译完成的项目代码进行打包，打包成容器应用镜像

第四步：jenkins把打包的容器应用镜像上传到harbor

第五步：jenkins通过ssh插件完成对web-server进行运行容器应用镜像的操作

5.6.2 创建项目任务
