前面做过jenkins发布nodejs项目,使用ssh插件,这回没有使用ssh插件。 1、将项目、发布动作、主机作为参数,配置参数化构建 2、配置拉取git仓库项目 3、构建环境选项nodejs 4、编写构建脚
前面做过jenkins发布nodejs项目,使用ssh插件,这回没有使用ssh插件。
1、将项目、发布动作、主机作为参数,配置参数化构建
2、配置拉取git仓库项目
3、构建环境选项nodejs
4、编写构建脚本

/home/lucky-front/$project目录创建好以下三个文件
Dockerfile文件
[root@master trucpal]# cat Dockerfile FROM ubuntu:latest RUN apt-get update RUN apt-get install -y vim RUN apt-get install -y nginx RUN apt-get install -y net-tools COPY nginx.conf /etc/nginx/nginx.conf RUN ln -sf /dev/stdout /var/log/nginx/access.log && ln -sf /dev/stderr /var/log/nginx/error.log RUN mkdir /usr/local/www COPY $project /usr/local/www/$project ENV TZ=Asia/Shanghai RUN set -eux; \ ln -snf /usr/share/zoneinfo/$TZ /etc/localtime; echo $TZ > /etc/timezone WORKDIR /home CMD ["nginx","-g","daemon off;"]yaml文件
