Day 4 — Practical Application and Troubleshooting

Today's lessons

Today concentrates on real-world CI/CD troubleshooting and optimization. Students will learn to diagnose and resolve common workflow issues, implement effective backup strategies, and conduct thorough code reviews. The day emphasizes practical problem-solving skills and pipeline optimization techniques for robust TYPO3 deployments.

Prerequisites and goals

Prerequisites

Theoretical prerequisites

This day assumes that you already know the following:

  • Understand how these advanced deployment strategies can minimize downtime and risk
  • Know the tools and methodologies used for automated testing, including unit tests, integration tests, and end-to-end tests
  • Understand different backup techniques and the importance of data redundancy
  • Understand how to effectively plan and execute backups in continuous deployment environments

Practical prerequisites

Before you start this day, please have the following things ready:

  • Used a continuous integration and continuous deployment pipeline for code contribution in a team with other contributors
  • Set up, execute, and monitor advanced deployment techniques
  • Write and run various types of automated tests, and integrate these tests into their deployment pipelines
  • Implement a backup system that complements their CI/CD setup
  • Fixed issues discovered in failed automated and manual code reviews
  • Deployed database schema changes and automated data migrations using TYPO3 core technologies

Goals

Theoretical goals

By the end of this day, you should know the following:

  • The most common tools for automated quality assurance in PHP-based continuous integration workflows
  • Backup best practices for continuous deployment environments
  • Best practices for code review
  • Techniques for effective troubleshooting, including identifying and resolving conflicts, handling failed deployments, and debugging post-deployment issues in TYPO3
  • Understand how to evaluate and refine deployment processes to reduce deployment times, minimize downtime, and improve overall efficiency in their CI/CD pipelines

Practical goals

By the end of this day, you should have completed the following:

  • Integrate all elements of CI/CD from previous days
  • Ensuring the pipeline is robust, efficient, and fully functional
  • Adapt and customize deployment workflows
  • Address unique project constraints and requirements
  • Use tools and techniques to streamline processes, improve pipeline performance, and ensure scalability
