Creating the secret key

Kubernetes secret objects enable you to store and manage sensitive information.

To create the secret key:

1. Obtain the client admin key.
2. Log in using SSH to the Ceph cluster node in which Ceph-mon is running, and then:
   1. Run the following command:
      ceph auth get-key client.admin
   2. If the preceding step does not provide the key, obtain it from the /etc/ceph/ceph.client.admin.keyring file.
3. Obtain the base64 value of the key by running the following command:

echo -n {key} | base64

4. Create a sample YAML file for the secret key with the following content:

apiVersion: v1

kind: Secret

metadata:

     name: ceph-secret (provide any random name as per choice)

     namespace: ceph-storage-integration

data:

     key: WSA45BYUDNSJGFJKFDGHJDHFGJsdfbusygo76t32SDDSHFGDSFG=

type: kubernetes.io/rbd

Note: Replace the name, namespace, and key values to match your environment.

5. Save the file in the OpenShift master node as secret-file.yaml.
6. To create the secret key in the OpenShift master node, run the following command:

oc create -f secret-file.yaml
