title: How to install Nodejs 8.12 in alpine:3.8?
body: <p>I am writing a Dockerfile to dockerize a sample nodejs app. I developed that in <code>Nodejs v8.12</code> and <code>npm 6.4.1</code>. I know that I can use <code>node:8.12-alpine</code> image to get results. But I am using <code>alpine:3.8</code> image which is officially recommended. </p>
  
  <p>My Dockerfile contents are below if I use that to build image I will end up in downloading latest version of nodejs from alpine repo. I don't want that to happen, So I planned to install the package manually for the purpose of reproducible. The saddest part is I am unable to find apk version of <code>Nodejs v8.12</code> and <code>npm</code>. </p>
  
  <p>Can any one help me on where can I find apk for <code>Nodejs v8.12</code> or how to install this version of Nodejs to my image manually?</p>
  
  <p><code>FROM alpine:3.8
  WORKDIR /app
  RUN apk add --update nodejs nodejs-npm
  COPY . ./
  RUN npm install
  EXPOSE 9001
  CMD [ "npm", "start" ]</code></p>
