容器化案例三:NodeJS服务容器化

公司部分教研、课件服务使用Nodejs实现，这篇文章记录相关服务容器化内容。

编译打包

npm install

Dockerfile文件编写

FROM harbor.k8s.xxx.com/iflow_public/slide:node-pdf.1.0.6

ADD ./target.tar.gz /data/source/node-pdf

RUN echo '127.0.0.1 local.xxx.com' >> /etc/hosts

WORKDIR /data/source/node-pdf

Deployment及Service文件编写

{{$MODULE := "serve" }}
{{$TRUE_APP_NAME := (printf "%v-%v" .Env.FLOW_STANDARD_NAME $MODULE)}}
