Deploying CTE Kubernetes Storage Classes

For information on K8 storage classes, see Storage Classes for more information.

Note

All of the Kubernetes clients that you want to attach to a storage group must have the same Kubernetes Namespace and Kubernetes structureless pods.

To deploy a storage class for CTE for Kubernetes:

1. Create and save a registration token in CM. See Tokens for more information.

   

   Note

   Select Base64 format for the registration token, if using CipherTrust Manager v2.10 and subsequent versions.

2. Create a K8s Storage Group in CipherTrust Manager. See Creating a K8s Storage Group for more information.

3. If using CipherTrust Manager v2.9 or previous versions, encode the token in base64 format, type:

   echo -n <CM REGISTRATION TOKEN STRING> | base64 -w 0

   Copy

4. Copy the base64 encoding to create a Kubernetes secret YAML file, cte-csi-cmtoken.yaml:

   apiVersion: v1
   kind: Secret
   metadata:
     name: <CHANGE to name of the K8s secret. For example: cm-reg-token>
   type: Opaque
   data:
     # This is a base64 encoded registration token.  To generate:
     # echo <CM REGISTRATION TOKEN STRING> | base64 -w 0
     registration_token: bWlEaUJlZ08xNkNsbndqZmc4a1dvcU1SUG9uaVpnNkVtUjVYSGFLUVZVTHRhbGRrb0M5T1ZwTEpvTXp4UldmSQ==

   Copy

5. The name of the K8s secret must be embedded in the registration_token_secret parameter in the storage class YAML file. Use the YAML file, cte-storageclass.yaml and fill in the appropriate values.

   apiVersion: storage.k8s.io/v1
   kind: StorageClass
   metadata:
     name: <CHANGE to name of the Kubernetes Storage Class. For example: csi-test-sc>
   provisioner: csi.cte.cpl.thalesgroup.com
   reclaimPolicy: Delete
   volumeBindingMode: Immediate
   allowVolumeExpansion: true
   parameters:
   
     # Domain name or IP address of the CipherTrust Manager (Required)
     key_manager_addr: <CHANGE_ME to your CM IP ADDR>
   
     # Name of the CipherTrust Manager K8s Storage Group. (Required)
     k8_storage_group: <CHANGE to the name of the Kubernetes Storage Group. For example: test-group>
   
     # Kubernetes Secret with CM registration token (Required)
     registration_token_secret: <CHANGE to the K8s secret. For example: cm-reg-token>
   
     # Time in minutes to wait before unregistering from the CipherTrust Manager
     # once all of the volumes have been unguarded. Parameter must be added as a string
     # integer value. Default is 10 minutes. (Optional)
     registration_period: "10"

   Copy

6. Record the storage class name, for further use. Deploy by typing:

   kubectl apply -f cte-csi-cmtoken.yaml
   kubectl apply -f cte-storageclass.yaml

   Copy
