Secrets Store CSI Driver

Secrets Store CSI Driver — Kubernetes SIG project to mount secrets from external vaults as volumes.

-

Our Verdict

The standard way to surface external vault secrets into Kubernetes pods; fine but not magical.

Pros

  • Mounts external vault secrets as K8s volumes
  • Kubernetes-SIG project with wide vendor support
  • Keeps secrets out of etcd if you want
  • Works with Vault, AWS, Azure, GCP

Cons

  • Kubernetes-only, not a standalone solution
  • Provider plugins vary in maturity
  • Volume-based model is leaky vs direct SDK
  • Rotation semantics require care
Best for: Kubernetes teams integrating external secret stores into workloads. Not for: Non-K8s environments or teams wanting a full vault.
