Dockerfile & Image Release Automation

This repository contains a small Python helper script, doc-dockerfile.py, which bootstraps a GitHub Actions workflow to:

1. Generate a basic Dockerfile
2. Build a Docker image from it
3. Save the image as a image.tar archive
4. Create and push a timestamped Git tag
5. Create a GitHub Release for that tag

---

Prerequisites

• Python 3
  • Tested on Python 3.6+.

---

Files

• doc-dockerfile.py
  A Python script that creates /\.github/workflows/gen-dockerfile.yml containing the full CI/CD pipeline.

• .github/workflows/gen-dockerfile.yml (generated)
  Defines a single workflow, build-and-release, that runs on pushes to main.

---

Getting Started

1. Clone your repo (if you haven’t already):

   git clone git@github.com:ImNotVarun/Automated-Build-Deployment-Workflow.git
   cd Automated-Build-Deployment-Workflow

2. Run the generator script:

   python3 doc-dockerfile.py

   • If a workflow already exists, the script will do nothing.
   • Otherwise, it will:
     1. Create .github/workflows/gen-dockerfile.yml
     2. Prompt you to commit & push.

---

What Happens Next

• On every push to main:
  1. GitHub Actions spins up an Ubuntu VM.
  2. It checks out your code.
  3. It echoes a minimal Dockerfile.
  4. It builds the Docker image (docker build).
  5. It saves the image as image.tar.
  6. It creates & pushes a timestamped Git tag (vYYYYMMDDHHMMSS).
  7. It creates a GitHub Release for that tag.
  8. It uploads only image.tar as the release asset.
