IBM VPC Block
Container Storage Interface (CSI) Driver provides a CSI
interface used by Container Orchestrators to manage the lifecycle of IBM VPC Block Data volumes.
The following are the supported orchestration platforms suitable for deployment for IBM VPC Block CSI Driver.
Orchestration platform | Version | Architecture |
---|---|---|
Red Hat® OpenShift® | 4.7 | x86 |
Red Hat® OpenShift® | 4.8 | x86 |
Red Hat® OpenShift® | 4.9 | x86 |
Kubernetes | 1.19 | x86 |
Kubernetes | 1.20 | x86 |
Kubernetes | 1.21 | x86 |
Following are the prerequisites to use the IBM VPC Block CSI Driver:
- User should have either Red Hat® OpenShift® or kubernetes cluster on IBM VPC Gen 2 infrastructure.
- Should have compatible orchestration platform.
- Install and configure
ibmcloud is
CLI or get the required worker/node details by usingIBM Cloud Console
- Cluster's worker node should have following labels, if not please apply labels before deploying IBM VPC Block CSI Driver.
"ibm-cloud.kubernetes.io/worker-id"
"failure-domain.beta.kubernetes.io/region"
"failure-domain.beta.kubernetes.io/zone"
"topology.kubernetes.io/region"
"topology.kubernetes.io/zone"
Please use apply-required-setup.sh
script for all the nodes in the cluster which will need couple of inputs like
instanceID
: That you can get from ibmcloud is ins
node-name
: this is as per node name in the kubernetes node check by using kubectl get nodes
region-of-instanceID
: region of the instanceID, this you can get the by using ibmcloud is in <instanceID>
zone-of-instanceID
: Zone of the instanceID, this you can get the by using ibmcloud is in <instanceID>
Example :- ./apply-required-setup.sh
For building the driver docker
and GO
should be installed on the system
-
GO version should be >=1.16
-
Set the
GOPATH
environment variable. -
Build the driver image
$ mkdir -p $GOPATH/src/github.com/kubernetes-sigs $ cd $GOPATH/src/github.com/kubernetes-sigs/ $ git clone https://github.com/kubernetes-sigs/ibm-vpc-block-csi-driver.git $ cd ibm-vpc-block-csi-driver
$ make
$ make buildimage
Image should be pushed to any registry from which cluster worker nodes have access to pull
You can push the driver image to docker.io registry or IBM public registry under your namespace.
For pushing to IBM registry:
Create an image pull secret in your cluster
-
ibmcloud login to the target region
-
Run - ibmcloud cr region-set global
-
Run - ibmcloud cr login
-
Make sure kubectl is configured to use the cluster
-
Review and retrieve the following values for your image pull secret.
<docker-username>
- Enter the string:iamapikey
.<docker-password>
- Enter your IAM API key. For more information about IAM API keys, see Understanding API keys .<docker-email>
- Enter the string: iamapikey. -
Run the following command to create the image pull secret in your cluster. Note that your secret must be named icr-io-secret
kubectl create secret docker-registry icr-io-secret --docker-server=icr.io --docker-username=iamapikey --docker-password=-<iam-api-key> --docker-email=iamapikey -n kube-system
-
- Edit slclient_Gen2.toml for your cluster.
IBM VPC endpoints which supports Gen2 is documented here
- Install
kustomize
tool. The instructions are available here - Export cluster config i.e configuring kubectl command
- Deploy IBM VPC Block CSI Driver on your cluster
-
You can use any overlays available under
deploy/kubernetes/driver/kubernetes/overlays/
and edit the image tag if you want to use your own build image from this source code, although default overlays are already using released IBM VPC Block CSI Driver image -
gcr.io/k8s-staging-cloud-provider-ibm/ibm-vpc-block-csi-driver:master
image is always the latest image build usingmaster
branch code. -
Example using
stage
overlay to update the image tag- Change
iks-vpc-block-driver
image name indeploy/kubernetes/driver/kubernetes/overlays/stage/controller-server-images.yaml
- Change
iks-vpc-block-driver
image name indeploy/kubernetes/driver/kubernetes/overlays/stage/node-server-images.yaml
- Change
-
Deploy plugin
bash deploy/kubernetes/driver/kubernetes/deploy-vpc-block-driver.sh stage
-
- Create storage classes
ls deploy/kubernetes/storageclass/ | xargs -I classfile kubectl apply -f deploy/kubernetes/storageclass/classfile
- Create PVC
kubectl create -f examples/kubernetes/validPVC.yaml
- Create POD with volume
kubectl create -f examples/kubernetes/validPOD.yaml
- Delete plugin
bash deploy/kubernetes/driver/kubernetes/delete-vpc-csi-driver.sh stage

Pull requests are very welcome! Make sure your patches are well tested. Ideally create a topic branch for every separate change you make. For example:
-
Fork the repo
-
Create your feature branch (git checkout -b my-new-feature)
-
Commit your changes (git commit -am 'Added some feature')
-
Push to the branch (git push origin my-new-feature)
-
Create new Pull Request
-
Add the test results in the PR
For any changes to go.mod
or go.sum
, be sure to run go mod vendor
to update dependencies in the vendor/
directory. You can verify that the vendor directory is up-to-date before filing a PR by running hack/verify-vendor.sh
