Docker Image Build and Publication Guide¶

This document describes how to build and publish a Docker image for your project using a clean, cache-free build process, and push it to Docker Hub with the latest tag.

Prerequisites¶

Docker must be installed and running.
A valid Dockerfile must be present at the root of the project.
You must have a Docker Hub account (https://hub.docker.com/).
You must be logged in with docker login.

Clean Build (No Cache)¶

To build the image without using Docker’s layer cache:

docker build --no-cache -t your-username/your-project:latest .

Replace your-username/your-project with your actual Docker Hub repository name.

Publishing to Docker Hub¶

Once the image is built, you can push it to Docker Hub using:

docker push your-username/your-project:latest

Verification¶

You can verify the image is available online by visiting:

https://hub.docker.com/r/your-username/your-project

Additional Notes¶

Ensure your dependencies are up to date and reflected in the appropriate files.
To free up space from old layers and unused images:

docker system prune -f
