How to install Nodejs 8.12 in alpine:3.8?

The question already answered but today I was facing issue so this is how i build with nodejs 8 in Alpine

FROM alpine:3.8RUN apk add  --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/v3.7/main/ nodejs=8.9.3-r1

You can find node 8 in Alpine repo v3.7

https://pkgs.alpinelinux.org/packages?name=nodejs&branch=v3.7

you can find node version details here, branch convention is v3.x

Taking references from : https://github.com/nodejs/docker-node
