username_0: node:10 was good for getting started, but image is far too large for development

comparing build speeds of docker-compose.db.yml vs *.all.yml tells the story
<issue_comment>username_0: [multi stage build](https://github.com/mhart/alpine-node#example-dockerfile-for-your-own-nodejs-project)
<issue_comment>username_0: ✅switched to alpine-node
<issue_comment>username_0: going to skip multi-stage build for now. not sure it's necessary since I'm not pulling built image from registry<issue_closed>
