Episode 75 — CI/CD and GitOps: pipelines, shift-left testing, DevSecOps vocabulary

Linux+ tests CI/CD and GitOps vocabulary because modern Linux administration often happens through pipelines, not through manual terminal changes, and the exam expects you to understand the operational implications. This episode explains pipelines as automated stages that build, test, and deploy changes, and it frames GitOps as the approach where the desired state lives in version control and deployments follow the repository as the source of truth. You’ll learn what “shift-left testing” means in practical terms: catching issues earlier in the lifecycle reduces outages, rework, and security exposure. The focus is on language and intent: exam questions may describe a workflow and ask you to identify whether it is CI/CD, GitOps, or a DevSecOps practice, and to infer why it improves reliability and security.

we apply these concepts to troubleshooting and best practices that matter in real operations. You’ll practice recognizing pipeline failure types: build failures due to dependencies, test failures due to environment mismatch, and deploy failures due to permissions or drift between target systems. We also cover operational guardrails: approvals, rollbacks, artifact versioning, and the importance of separating configuration from code so deployments remain reproducible. Finally, you’ll learn exam-aligned decision-making: treat pipelines as controlled change mechanisms, enforce security checks as part of the workflow rather than after the fact, and use Git as the authoritative record so changes are auditable, reversible, and less dependent on individual administrators’ memory.
