11.2. Creating an Object Bucket Claim using the command line interface

Procedure

1. Use the command-line interface to generate the details of a new bucket and credentials.

   Run the following command:

   # noobaa obc create <obc-name> -n openshift-storage

   Replace <obc-name> with a unique OBC name, for example, myappobc.

   Additionally, you can use the --app-namespace option to specify the namespace where the OBC configuration map and secret will be created, for example, myapp-namespace.

   For example:

   INFO[0001] ✅ Created: ObjectBucketClaim "test21obc"

   The MCG command-line-interface has created the necessary configuration and has informed OpenShift about the new OBC.

2. Run the following command to view the OBC:

   # oc get obc -n openshift-storage

   For example:

   NAME        STORAGE-CLASS                 PHASE   AGE
   test21obc   openshift-storage.noobaa.io   Bound   38s

3. Run the following command to view the YAML file for the new OBC:

   # oc get obc test21obc -o yaml -n openshift-storage

   For example:

   apiVersion: objectbucket.io/v1alpha1
   kind: ObjectBucketClaim
   metadata:
     creationTimestamp: "2019-10-24T13:30:07Z"
     finalizers:
     - objectbucket.io/finalizer
     generation: 2
     labels:
       app: noobaa
       bucket-provisioner: openshift-storage.noobaa.io-obc
       noobaa-domain: openshift-storage.noobaa.io
     name: test21obc
     namespace: openshift-storage
     resourceVersion: "40756"
     selfLink: /apis/objectbucket.io/v1alpha1/namespaces/openshift-storage/objectbucketclaims/test21obc
     uid: 64f04cba-f662-11e9-bc3c-0295250841af
   spec:
     ObjectBucketName: obc-openshift-storage-test21obc
     bucketName: test21obc-933348a6-e267-4f82-82f1-e59bf4fe3bb4
     generateBucketName: test21obc
     storageClassName: openshift-storage.noobaa.io
   status:
     phase: Bound

4. Inside of your openshift-storage namespace, you can find the configuration map and the secret to use this OBC. The CM and the secret have the same name as the OBC.

   Run the following command to view the secret:

   # oc get -n openshift-storage secret test21obc -o yaml

   For example:

   apiVersion: v1
   data:
     AWS_ACCESS_KEY_ID: c0M0R2xVanF3ODR3bHBkVW94cmY=
     AWS_SECRET_ACCESS_KEY: Wi9kcFluSWxHRzlWaFlzNk1hc0xma2JXcjM1MVhqa051SlBleXpmOQ==
   kind: Secret
   metadata:
     creationTimestamp: "2019-10-24T13:30:07Z"
     finalizers:
     - objectbucket.io/finalizer
     labels:
       app: noobaa
       bucket-provisioner: openshift-storage.noobaa.io-obc
       noobaa-domain: openshift-storage.noobaa.io
     name: test21obc
     namespace: openshift-storage
     ownerReferences:
     - apiVersion: objectbucket.io/v1alpha1
       blockOwnerDeletion: true
       controller: true
       kind: ObjectBucketClaim
       name: test21obc
       uid: 64f04cba-f662-11e9-bc3c-0295250841af
     resourceVersion: "40751"
     selfLink: /api/v1/namespaces/openshift-storage/secrets/test21obc
     uid: 65117c1c-f662-11e9-9094-0a5305de57bb
   type: Opaque

   The secret gives you the S3 access credentials.

5. Run the following command to view the configuration map:

   # oc get -n openshift-storage cm test21obc -o yaml

   For example:

   apiVersion: v1
   data:
     BUCKET_HOST: 10.0.171.35
     BUCKET_NAME: test21obc-933348a6-e267-4f82-82f1-e59bf4fe3bb4
     BUCKET_PORT: "31242"
     BUCKET_REGION: ""
     BUCKET_SUBREGION: ""
   kind: ConfigMap
   metadata:
     creationTimestamp: "2019-10-24T13:30:07Z"
     finalizers:
     - objectbucket.io/finalizer
     labels:
       app: noobaa
       bucket-provisioner: openshift-storage.noobaa.io-obc
       noobaa-domain: openshift-storage.noobaa.io
     name: test21obc
     namespace: openshift-storage
     ownerReferences:
     - apiVersion: objectbucket.io/v1alpha1
       blockOwnerDeletion: true
       controller: true
       kind: ObjectBucketClaim
       name: test21obc
       uid: 64f04cba-f662-11e9-bc3c-0295250841af
     resourceVersion: "40752"
     selfLink: /api/v1/namespaces/openshift-storage/configmaps/test21obc
     uid: 651c6501-f662-11e9-9094-0a5305de57bb

   The configuration map contains the S3 endpoint information for your application.
