Installing the Kubernetes Secret Store CSI

1. Create an OpenShift Project to deploy the CSI into

   Copy

   oc new-project k8s-secrets-store-csi
   

2. Set SecurityContextConstraints to allow the CSI driver to run (otherwise the DaemonSet will not be able to create Pods)

   Copy

   oc adm policy add-scc-to-user privileged \
     system:serviceaccount:k8s-secrets-store-csi:secrets-store-csi-driver
   

3. Add the Secrets Store CSI Driver to your Helm Repositories

   Copy

   helm repo add secrets-store-csi-driver \
     https://kubernetes-sigs.github.io/secrets-store-csi-driver/charts
   

4. Update your Helm Repositories

   Copy

   helm repo update
   

5. Install the secrets store csi driver

   Copy

   helm install -n k8s-secrets-store-csi csi-secrets-store \
     secrets-store-csi-driver/secrets-store-csi-driver \
     --version v1.3.2 \
     --set "linux.providersDir=/var/run/secrets-store-csi-providers"
   

6. Check that the Daemonsets is running

   Copy

   oc -n k8s-secrets-store-csi get pods -l "app=secrets-store-csi-driver"
   

   You should see the following

   Copy

   NAME                                               READY   STATUS    RESTARTS   AGE
   csi-secrets-store-secrets-store-csi-driver-cl7dv   3/3     Running   0          57s
   csi-secrets-store-secrets-store-csi-driver-gbz27   3/3     Running   0          57s
   

7. Add pod security profile label for CSI Driver

   This is required starting in OpenShift v4.13
   Copy

   oc label csidriver/secrets-store.csi.k8s.io security.openshift.io/csi-ephemeral-volume-profile=restricted
