Description

Hi,

First, thank for sharing your code with us. I was wondering why you use a node:6 images as based image since its weight is 654MB which is pretty heavy. I would suggest to move to an alpine based such as mhart/alpine-node which weight 49,08MB.

By the way, the "david" image doesn't seems to be on docker hub.

Research direction
First, locate the Dockerfile in the repository at 'alanshaw/david www'. The issue suggests changing the base image from 'node:6' to an Alpine based image like 'mhart/alpine node' to reduce image size. The change is straightforward: replace the FROM line and ensure any subsequent commands still work (e.g., package installation). Check if there are any specific dependencies that require glibc or other libraries not present in Alpine. Since the issue is from 2016 and the repository uses Node.js, verify the current Node.js version compatibility. No linked PRs or comments provide further guidance.
