One single Docker base image may be used throughout several stages of a build, including compilation, packaging, and unit testing. Considering that lts-buster is a static picture, this method may be preferable. Instead of using node:latest, you should use the lts-buster Docker image. # Create image based on the official Node image from dockerhubĬOPY package-lock.json.
