Sprint 01

In Sprint-01, you’ll lay the groundwork for your DevOps pipeline by:

1. Creating and configuring a GitHub repository.

2. Applying organizational best practices (branching strategy, repository settings).

3. Writing a sample Dockerfile and building the image.

4. Running and testing the Docker image locally.

   

5. Pushing the tested code and Docker image to GitHub.

   

1. GitHub Repository Setup

1. Sign in to your GitHub account and click New repository.
2. Name the repo according to your organization’s naming convention (e.g., project-name).
3. Add a README.md, .gitignore, and your preferred branch protection rules.
4. Clone the repo locally:

   git clone [email protected]:your-org/project-name.git
   cd project-name
   

2. Apply Organizational Best Practices

• Establish a branching strategy (e.g., main, develop, feature branches).
• Create issue and PR templates under .github/.
• Configure automated workflows or GitHub Actions as needed.

3. Sample Dockerfile and Image Build

Create a Dockerfile in the project root:

FROM alpine:3.18
WORKDIR /app
COPY . .
RUN apk add --no-cache python3 py3-pip \
 && pip3 install --no-cache-dir -r requirements.txt
CMD ["python3", "app.py"]

Build the Docker image:

docker build -t your-org/project-sample:latest .

4. Local Testing of Docker Image

Run the container and verify functionality:

docker run --rm -d -p 8080:80 your-org/project-sample:latest
curl http://localhost:8080/health

5. Push to GitHub

1. Stage and commit your changes:

   git add .
   git commit -m "Initialize repo and add Dockerfile"
   

2. Push to the remote:

   git push origin main
   

That wraps up Sprint-01. You’ve now initialized the repository, enforced best practices, built and tested your Docker image, and pushed it to GitHub. Let’s continue to Sprint-02 for CI/CD integration!
