8.2. 使用命令行界面创建对象 Bucket 声明

流程

1. 使用命令行界面生成新 bucket 和凭据的详细信息。运行以下命令：

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

   Copy to Clipboard Toggle word wrap

   将 <obc-name> 替换为一个唯一的对象 Bucket Claim 名称，例如 myappobc。

   另外，您可以使用 --app-namespace 选项指定创建 Object Bucket Claim 配置映射和 secret 的命名空间，如 myapp-namespace。

   输出示例：

   INFO[0001] ✅ Created: ObjectBucketClaim "test21obc"

   Copy to Clipboard Toggle word wrap

   MCG 命令行界面已创建了必要的配置，并已向 OpenShift 告知新的 OBC。

2. 运行以下命令来查看对象 Bucket 声明：

   # oc get obc -n openshift-storage

   Copy to Clipboard Toggle word wrap

   输出示例：

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

   Copy to Clipboard Toggle word wrap

3. 运行以下命令，以查看新对象 Bucket 声明的 YAML 文件：

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

   Copy to Clipboard Toggle word wrap

   输出示例：

   apiVersion: objectbucket.io/v1alpha1
   kind: ObjectBucketClaim
   metadata:
     creationTimestamp: "2019-10-24T13:30:07Z"
     finalizers:
     - objectbucket.io/finalizer
     generation: 2
     labels:

     namespace: openshift-storage
     resourceVersion: "40756"
     selfLink: /apis/objectbucket.io/v1alpha1/namespaces/openshift-storage/objectbucketclaims/test21obc

     generateBucketName: test21obc
     storageClassName: openshift-storage.noobaa.io
   status:
     phase: Bound

4. 在 openshift-storage 命名空间内，您可以找到配置映射和 secret 来使用此 Object Bucket Claim。CM 和 secret 的名称与 Object Bucket Claim 的名称相同。查看 secret：

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

   输出示例：

   apiVersion: v1
