Cloud Native CI/CD with GitLab

Key Takeaways

In this section and the previous one, we covered key GitLab CI/CD concepts: pipelines, stages, jobs, and runners.

We demonstrated the flexibility of defining jobs in pipelines and the differences between using YAML anchors and extends to manage reusable configurations. We also introduced default stages (.pre and .post), and showed how to run commands before and after the main pipeline stages.

Finally, we discussed the newer stageless pipelines, which use the needs keyword to create more dynamic workflows by defining dependencies between jobs.

Understanding these core concepts lays the foundation for building, optimizing more complex pipelines and extending GitLab capabilities.

Here's a summary of the key takeaways:

• A pipeline consists of jobs, which are grouped into stages. Jobs within the same stage run in parallel, while stages execute sequentially.

• Jobs can have any name, and multiple jobs can exist within a single stage.

• The script section defines the commands executed in a job, and you can handle command failures using shell operators like ||
