Docker+Jenkins持续集成环境(2)使用docker+jenkins构建nodejs前端项目

前文使用Docker搭建Jenkins+Docker持续集成环境我们已经搭建了基于docker+jenkins的持续集成环境,并构建了基于maven的项目。这一节,我们继续扩展功能,增加对Nodejs的支持,实现nodejs项目构建、并打包成docker镜像和自动部署。

1. 配置Nodejs环境

1.1 安装nodejs插件

打开系统管理——管理插件——可选插件,搜索NodeJS,选择NodeJS Plugin安装

1.2 配置nodejs 版本

系统管理 —— 全局工具配置 —— NodeJS,选择安装nodejs,选择当前最新版本9.4,命名NodeJS 9.4。

2. 配置项目

2.1 新建项目

新建jenkins项目,选择自由项目,按前文说明配置好SVN、触发器。

在构建环境里,选择Provide Node & npm bin/ folder to PATH,选择我们配置的9.4版本nodejs

2.2 配置构建命令

一般是通过npm命令构建,我们选择增加构建步骤 —— Excute shell,输入构建命令:

alias cnpm="npm --registry=https://registry.npm.taobao.org \
--cache=$HOME/.npm/.cache/cnpm \
--disturl=https://npm.taobao.org/dist \
--userconfig=$HOME/.cnpmrc"
cnpm install 
cnpm run build

注意,这里为了构建更快,选择通过alias增加cnpm指令,指定使用淘宝的仓库。

2.3 构建docker镜像

由于我们构建出来的已经是可访问的资源了,放在dis目录,所以我们可以基于nginx作为基础镜像。 编写DockerFile:

FROM nginx
ADD ./dist /usr/share/nginx/html
EXPOSE 80

然后,增加构建步骤,ADD build/publish docker image 设置image:192.168.86.8:5000/allinone-web-cicd 勾上push image,会自动push到192.168.86.8:5000仓库

2.4 自动部署镜像

和上文一样,这里继续使用ssh实现docker镜像部署。

增加构建步骤,Execute shell script on remote host using ssh:

选择docker swarm的manager机器,输入命令:

docker service rm  allinone-web-cicd
docker service create --name allinone-web-cicd --replicas 1 --publish 10081:80 192.168.86.8:5000/allinone-web-cicd

这次,我们使用docker service来实现部署,先service rm掉老服务,然后create新服务。

3.测试构建

稍等片刻,就构建成功了;

这个时候,访问swarm集群的任一http://ip:10081,就可以看到效果了。
