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

    1. 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.

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

    oc create -f secret-file.yaml
