CI/CD Best Practices

What this best practices guide is

A practical guide to CI/CD best practices for teams that ship code through a pipeline. It covers integrating small changes often, keeping the build fast and green, securing workflows and their credentials, building artifacts once with provenance, deploying gradually with canaries and fast rollback, and measuring delivery with the DORA metrics.

It has 6 chapters and 25 practices, each with why it matters, what to do and what to avoid. For developers and DevOps engineers.

Chapter by chapter

1. Integrating small changes often (4 practices)

How code should flow into main so that integration is continuous in practice, not just in name: trunk-based development, small batches and a main branch that is always releasable.

2. Fast feedback and tests you can trust (4 practices)

A pipeline people trust is one that answers quickly and honestly. These practices keep builds fast and failures meaningful.

3. Securing the pipeline (5 practices)

A CI system runs code with credentials to your cloud and your registry. These practices, from the GitHub Actions security guidance, keep it from becoming the easiest way in.

4. Artifacts and supply chain (4 practices)

What the pipeline produces and how anyone can tell where it came from: build once, version immutably, record provenance and scan before release.

5. Deploying and releasing safely (5 practices)

How to make deployment routine: fully automated, gradual, separated from feature release and quick to undo.

6. Measuring delivery with DORA metrics (3 practices)

How to tell whether the pipeline is getting better: the five DORA software delivery metrics and how to use them without gaming them.

How it works on Sefism

The guide reads like a short course: a syllabus, then one chapter per page in a focused reader, with a quiz at the end of each chapter for members. The opening chapters are open to everyone. Adding it to your account uses credits, opens every chapter and keeps your progress.

Every claim is checked against the sources listed on the page (8 cited).
