Cloud Native CI/CD with GitLab

Key Takeaways

With this chapter, we entered the advanced usage of GitLab CI/CD syntax by exploring how to control job execution, timing, dependencies and more using the rules keyword. Here are the key takeaways:

• rules let you describe behavior, not just inclusion. A job can change when it runs, how it runs, and what it depends on, all from the same definition.

• Conditions are evaluated top-down. The first matching rule wins, so rule order is part of your control logic, not just formatting.

• when turns conditions into execution semantics. It bridges logic with pipeline state, allowing jobs to react to success, failure, manual intent, or time.

• Variables defined in rules are a powerful escape hatch. They let one job adapt across branches and contexts without cloning YAML.
