docker-image helps you build docker images 😉, without having to create a Dockerfile.
It currently supports node applications and expects the deployable files to be in ./dist.
npm i @olaleyeone/docker-image -D
$ npx docker-image
$ npx docker-image -t my-image
$ npx docker-image --from node:14.10.1-alpine3.12 -t my-image
