Project Overview
Part of the Introduction to Docker section of Coddy's Terminal journey — lesson 33 of 40.
In this project you will build a small greeting app image one step at a time, using the whole Docker workflow: writing a Dockerfile, building it into an image, copying a file inside, and running it.
You will start from the alpine base image, give your image a default command with CMD, personalize it with a COPY'd file, and finish by shipping a version-tagged release. Each lesson rebuilds the image with one more capability.
Challenge
BeginnerTo start, confirm your toolbox is ready: list the alpine images you will build on top of with docker images alpine.
