CSI (Container Storage Interface) - CI/CD Glossary Definition
CSI is the Container Storage Interface, a standard that lets storage vendors plug block and file storage into Kubernetes without changing core code. A CSI driver provisions and attaches volumes for persistent volume claims.
Why it matters
A PVC stuck Pending often means no CSI driver or storage class can satisfy it, so a stateful workload (or a build needing a persistent cache volume) cannot start.
