This repository centralizes all Docker images in one place, simplifying the process of building and pushing Docker images.

Purpose

The primary goal of this repository is to streamline Docker image management by:

• Gathering all Docker images: Consolidates Dockerfiles into a single repository.
• Automating the build and push process: Uses GitHub Actions to build and push Docker images based on commit messages.

Folder Structure

Organize your repository as follows to ensure compatibility with the workflow:

/
  app1/
    Dockerfile
  app2/
    Dockerfile

• Each directory (app1, app2, etc.) should contain a Dockerfile.
• The name of each directory corresponds to the Docker image name.

Commit Message Format

To trigger the Docker build and push process, format your commit messages as follows:

build/<image_name>:<version>

• <image_name>: The directory name containing the Dockerfile.
• <version>: The version tag for the Docker image.

Examples

1. Commit Message for app1 Docker Image with Version 1.0.0:

   build/app1:1.0.0
   

2. Commit Message for app2 Docker Image with Version 2.1.0:

   build/app2:2.1.0
   

Workflow Behavior

• Valid Commits: Commits with messages that match the build/<image_name>:<version> format will trigger the Docker image build and push process.
• Invalid Commits: Commits not following the specified format will be skipped. The CI process will not build or push Docker images for these commits, ensuring that only relevant updates are processed.

Summary

By following these conventions, you ensure that Docker images are built and pushed automatically whenever a commit with the correct format is made. This approach helps maintain a well-organized repository and simplifies Docker image management.
