GitLab CI Overview

• What is GitLab CI?: Tool for continuous integration and deployment.
• Why Use GitLab CI?: Streamlines the process of building, testing, and deploying software.

Setting Up GitLab

• Create a GitLab account and project for hands-on work.
• Project initialization: Set visibility (private/public) and settings for user interface preferences.
• Project Configuration: Create .gitlab-ci.yml file for defining the CI/CD pipeline.

CI/CD Pipelines Basics

• Pipelines: Series of steps for building and testing software.
• Jobs: Individual tasks defined in the pipeline.
• YAML Configuration: Structure of the pipeline defined using YAML syntax.

Docker Fundamentals

• Why Docker?: Package applications into containers for consistency across environments.
• Creating Docker Images: Use a Dockerfile to define the environment and application requirements.
• Running Containers: Execute commands in isolated environments using Docker.

AWS Deployment

• Amazon Web Services (AWS): Cloud services for hosting applications.
• Static Website Hosting: Store static files in AWS S3 bucket.
• Elastic Beanstalk: Deploy applications without managing servers directly.

CI/CD Implementation Steps

1. Build Docker Image: Create Docker images using GitLab CI.
2. Push to Registry: Upload Docker images to GitLab's container registry.
3. Deploy to AWS Elastic Beanstalk: Automate deployment using AWS CLI commands.
4. Post Deployment Testing: Verify successful deployment via curl commands.

Continuous Integration vs. Continuous Deployment

• Continuous Integration: Regularly integrate code changes and run tests.
• Continuous Deployment: Automatically deploy every change to production.
• Continuous Delivery: Deploy changes to a staging environment with manual approval for production deployment.

Final Project Assignment

• Collaborate on a project to add your name to a list of course completers.
• Use GitLab for version control and pull requests.

Important Reminders

• Terminate AWS Services: Avoid unexpected charges by deleting unused AWS resources.
• Explore Further Learning: Resources for Unix commands, Kubernetes, and advanced GitLab features available in course notes.

Conclusion

• Encouragement to provide feedback and stay connected through social media.
• Reminder of the importance of continuous learning in the tech field.
