Dockerizing a Java 24 Project with Docker Init

Hello Wowlrd!

I’m starting a new series called “Docker Hour,” where I’ll publish a new Docker-related article every week. In the beginning, I’ll publish a new article every two weeks, for a total of 10 articles. I wanted to call the series “Docker Deca,” but I’m just making up too many names.

Later, I’ll give a talk at PlatformCon named:

Bake a Docker Cake:
10 Docker Commands You Didn’t Know About

It’s going to be about these 10 commands. So, let’s init!

Docker Init

Docker Init was a new command introduced in Docker Desktop 4.27 (for comparison, currently, the latest version is 4.40). It’s a “smart” command that helps you Dockerize your project. It does the following:

• Creates a Dockerfile
• Creates a docker-compose.yml file (well, they call it compose.yaml to be more of a cool guy)
• Creates a .dockerignore file
• Creates a README file with instructions on how to run the project

It’s great stuff! Let’s see it in action.

Technical Requirements

• Docker Desktop 4.27 or later
