When working with containers, you typically need to create a Dockerfile to define your image and a compose.yaml file to define how to run it.
To help you create these files, Docker Desktop has the docker init command. Run this command in a terminal within your project folder. docker init creates all the required files to containerize your application. This walkthrough shows you how this works.

Step 1: Run the command to create Docker assets
Choose one of your own applications that you would like to containerize, and in a terminal, run the following commands. Replace /path/to/your/project/ with the directory containing your project.
{{< include "open-terminal.md" >}}
$ cd /path/to/your/project/
$ docker init
Step 2: Follow the on-screen prompts
docker init walks you through a few questions to configure your project with sensible defaults. Specify your answers and press Enter.
Step 3: Try to run your application
Once you have answered all the questions, run the following commands in a terminal to run your project. Replace /path/to/your/project/ with the directory containing your project.
$ cd /path/to/your/project/
$ docker compose up
Step 4: Update the Docker assets
The docker init command tries its best to do the heavy lifting for you, but sometimes there's some assembly required. In this case, you can refer to the Dockerfile reference and Compose file reference to learn how to update the files created by docker init.
