Greetings, Developer! Ready for an epic journey? Together, we'll embark on a voyage from code creation to deploying your masterpiece on a Kubernetes cluster. Prepare to set sail!
1. Inception: Laying the Foundation
Your voyage begins by establishing a project in GitLab. Set the stage by defining the project's purpose and visibility settings, creating a canvas for your creative endeavors.
2. The Art of Git Flow: Setting Sail with Structure
As your project finds a home, make your first mark by initializing the repository with an initial commit. It's time to establish a Git branching strategy that harmonizes with your team's collaboration style.
3. Feature Quests and Code Review Expeditions
Navigate through feature branches, each one a quest in itself. Name them with care to reveal their essence. Engage in the code review rituals, where fellow developers provide valuable feedback, polishing your work to perfection.
4. Magic of CI/CD: Automating the Journey
Enter the realm of Continuous Integration and Continuous Deployment (CI/CD). Master `.gitlab-ci.yml` to orchestrate this magic. Create stages for building, testing, and deploying, and watch as your code sails through a series of automated jobs.
5. Quality Vigilance: Sonar's Watchful Gaze
Invoke SonarQube or SonarCloud to guard the code's quality. Unearth hidden bugs, code odors, and vulnerabilities, enhancing your code's brilliance.
6. Testing: The Shield of Assurance
Arm your code with tests—unit, integration, and end-to-end. These shields ensure your creation stands strong against the tides of uncertainty.
7. Environments: Realms of Validation
Guide your code through diverse environments. The development domain is your playground, UAT simulates user trials, preproduction imitates reality, and production delivers your masterpiece to the masses.
8. Deployment Magic: From Code to Reality
As your code conquers tests and environments, embark on the deployment journey. Start by unveiling it in the development realm. Gradually promote it through UAT and preproduction. The climax awaits in the production arena, involving meticulous planning, change requests, approvals, and the blessings of stakeholders.
9. Kubernetes Cluster: Navigating the Seas of Containerization
Enter the world of Kubernetes clusters—your vessel for code deployment. Chart your course within the intricate YAML manifests that define your application's voyage.
10. Deployment Strategies: A Duel of Techniques
In the realm of production deployments, two strategies dominate: rolling updates and blue-green deployments. Choose wisely, ensuring a seamless journey for your users.
11. Monitoring: The All-Seeing Beacon
Set up Azure Monitor or other monitoring tools to keep watch over your Kubernetes cluster. Metrics and insights become your map, revealing the health and performance of your voyage.
12. Navigating Errors: Challenges on the Horizon
Even the most illustrious voyages face challenges. Assemble logs through Azure Monitor Logs or the ELK Stack, and implement error tracking to swiftly address the unexpected.
13. Mastering Troubleshooting and Rollback Arts
No voyage is without storms. When deployment falters, decipher logs and metrics to unveil the root cause. Equip yourself with rollback strategies, a tactical retreat if needed.
14. Reflecting on the Odyssey: The Power of Learning
As you approach your journey's end, pause to reflect. Embrace the philosophy of continuous improvement, adapting your strategies based on lessons learned and insights gained.
15. Beyond the Horizon: Celebrating and Pioneering
Congratulations, Developer! Your odyssey from code inception to Kubernetes cluster deployment is an achievement to celebrate. With this newfound wisdom, venture forth to pioneer new frontiers in the dynamic realm of technology.
May your future journeys be marked by innovation, growth, and the thrill of shaping the digital landscape. Onward, to new horizons!
