3. 创建 AWS S3 存储桶：

   $ aws s3api create-bucket \
       --bucket $BUCKET \
       --region $REGION \
       --create-bucket-configuration LocationConstraint=$REGION 

   1

   us-east-1 不支持 LocationConstraint。如果您的区域是 us-east-1，忽略 --create-bucket-configuration LocationConstraint=$REGION。

4. 创建一个 IAM 用户：

   $ aws iam create-user --user-name velero 

   1

   如果要使用 Velero 备份具有多个 S3 存储桶的集群，请为每个集群创建一个唯一用户名。

5. 创建 velero-policy.json 文件：

   $ cat > velero-policy.json <<EOF
   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Action": [
                   "ec2:DescribeVolumes",
                   "ec2:DescribeSnapshots",
                   "ec2:CreateTags",
                   "ec2:CreateVolume",
                   "ec2:CreateSnapshot",
                   "ec2:DeleteSnapshot"
               ],
               "Resource": "*"
           },
           {
               "Effect": "Allow",
               "Action": [
                   "s3:GetObject",
                   "s3:DeleteObject",
                   "s3:PutObject",
                   "s3:AbortMultipartUpload",
                   "s3:ListMultipartUploadParts"
               ],
               "Resource": [
                   "arn:aws:s3:::${BUCKET}/*"
               ]
           },
           {
               "Effect": "Allow",
               "Action": [
                   "s3:ListBucket",
                   "s3:GetBucketLocation",
                   "s3:ListBucketMultipartUploads"
               ],
               "Resource": [
                   "arn:aws:s3:::${BUCKET}"
               ]
           }
       ]
   }
   EOF

6. 附加策略，为 velero 用户授予所需权限：

   $ aws iam put-user-policy \
     --user-name velero \
     --policy-name velero \
     --policy-document file://velero-policy.json

7. 为 velero 用户创建访问密钥：

   $ aws iam create-access-key --user-name velero

   Copy to Clipboard Toggle word wrap

   输出示例

   {
     "AccessKey": {
           "UserName": "velero",
           "Status": "Active",
           "CreateDate": "2017-07-31T22:24:41.576Z",
           "SecretAccessKey": <AWS_SECRET_ACCESS_KEY>,
           "AccessKeyId": <AWS_ACCESS_KEY_ID>
     }
   }

   Copy to Clipboard Toggle word wrap

8. 创建 credentials-velero 文件：

   $ cat << EOF > ./credentials-velero
   [default]
   aws_access_key_id=<AWS_ACCESS_KEY_ID>
   aws_secret_access_key=<AWS_SECRET_ACCESS_KEY>
   EOF

   Copy to Clipboard Toggle word wrap

   在安装数据保护应用程序前，您可以使用 credentials-velero 文件为 AWS 创建 Secret 对象。
