wyike / my-csi

my-csi

This is a sample CSI plugin implemented on vSphere cloud native storage. It's only a minimum implementation to make basic things work and learn to write an own CSI plugin skeleton.

Reference

• How to write a CSI plugin from scrach:

  • video series: https://www.youtube.com/watch?v=OIpX7WkJzOg&list=PLh4KH3LtJvRSAQsRLNLMDu6hd1uh6ZMoR (many thinks to Vivek)

• Also refer some code specific for vsphere from:

  • https://github.com/vmware/govmomi
  • https://github.com/kubernetes-sigs/vsphere-csi-driver/tree/master

Usage

• You have a kubernetes cluster
• Preparations
  • Edit manifests/deploy/controller-plugin.yaml to contain your VC Host, VC username, VC password
  • image wyike/my-csi:1.1.0 is on dockerhub. If you want to make yours and pull from your registry, please download source code and run:
    • make docker-image IMAGE_REGISTRY=<your-registry-store-path> IMAGE_NAME=<your-image-name> IMAGE_VERSION=<your-version>
    • then replace csi image in manifests/deploy/controller-plugin.yaml and manifests/deploy/node-plugin.yaml
• Apply yamls in manifests/deploy to have controller-plugin and node-plugin deployed
• Deploy storageclass with my-csi provisioner: manifests/test/sc.yaml
• Deploy PVC: manifests/test/pvc.yaml
• Deploy a Pod: manifests/test/pod.yaml
• Check a PV can be created automatically and Pod can start successfully
• Delete Pod
• Delete PVC
• Pod and PVC, PV can be deleted successfully
