SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Mount a Tencent COS bucket into a TKE pod as a ReadWriteMany PVC via the cosfs CSI driver. This enables apps to share user uploads and blobs through a regular filesystem path, while guiding on bucket naming, endpoints, and IAM scoping.

Core Features & Use Cases

  • Provides a scalable RWX storage layer by mounting COS as a PVC in Kubernetes, allowing multiple pods to read and write to the same bucket subpath.
  • Covers PV/PVC/Secret manifests, the <name>-<AppId> bucket naming rule, internal-vs-public endpoints, and cosfs caveats.
  • IAM: uses bucket-scoped CAM sub-user credentials, with per-namespace secrets and minimal privileges for uploads.

Quick Start

Configure cosfs in your cluster, create a COS bucket named your-bucket-name-AppId, set up a cos-secret in the workload namespace, and apply the PV, PVC, and deployment manifests.

FAQPage Schema
How do I mount Tencent COS as a PVC in Kubernetes?▼

Mount Tencent COS as a PVC by applying the cosfs CSI driver with PV, PVC, and Secret manifests to provision a ReadWriteMany volume for shared pod storage.

Can multiple pods read and write to the same COS bucket simultaneously?▼

Yes, multiple pods can read and write to the same COS bucket simultaneously. Mounting COS as a ReadWriteMany PVC provides a scalable shared storage layer for application blobs and uploads.

Do I need a specific bucket naming convention for cosfs in TKE?▼

Yes, you need a specific bucket naming convention for cosfs in TKE. Your COS bucket must be named using the your-bucket-name-AppId format to successfully mount via the CSI driver.

What IAM credentials are required to mount COS storage in Kubernetes?▼

Mounting COS storage requires bucket-scoped CAM sub-user credentials stored as a per-namespace secret. This enforces minimal privileges for uploads and optimizes cluster security.

How do I choose between internal and public COS endpoints for my PVC?▼

Choosing between internal and public COS endpoints for your PVC depends on your network path. Region-aware endpoints optimize cost and security, using internal endpoints for TKE cluster traffic.
