Ceph BucketNotifications 不會向 Kafka 推送消息

Question

我有一個ceph與三個節點測試集群radosgw安裝在第一個節點上。 ceph版本14.2.6 （f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9）鸚鵡螺（穩定）

# cat /etc/ceph/ceph.conf
[global]
fsid = a204e3b5-b0e1-4598-aadc-f46011b562f0

mon_initial_members = ceph-test-01, ceph-test-02, ceph-test-03
mon_host = 172.19.19.252,172.19.19.251,172.19.19.244

auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx

public network = 172.19.19.0/24

rgw_frontends = beast port=80

以及用於接收消息的 Apache Kafka 代理。

我根據官方CEPH文檔創建了一個主題：

（ https://docs.ceph.com/docs/master/radosgw/notifications/ ）。

POST http://ceph-test-01/?Action=CreateTopic&Name=bucketnotifications&push-endpoint=kafka://kafka-test-01:9092 with S3 credentials
Response:
<CreateTopicResponse xmlns="https://sns.amazonaws.com/doc/2010-03-31/">
    <CreateTopicResult>
        <TopicArn>arn:aws:sns:us::bucketnotifications</TopicArn>
    </CreateTopicResult>
    <ResponseMetadata>
        <RequestId>14804357-9c29-437d-9789-c127e1c13d23.44108.275</RequestId>
    </ResponseMetadata>
</CreateTopicResponse>

我創建了一個名為new-bucket並檢查了它的配置：

GET http://ceph-test-01/new-bucket?notification
Response:
<NotificationConfiguration>
    <TopicConfiguration>
        <Id>bucketnotifications</Id>
        <Topic>arn:aws:sns:us::bucketnotifications</Topic>
        <Event>s3:ObjectCreated:*</Event>
        <Event>s3:ObjectRemoved:*</Event>
    </TopicConfiguration>
</NotificationConfiguration>

當我向存儲桶添加或刪除文件時， ceph不會將通知推送到 Apache Kafka 主題。 Radosgw日志（調試模式開啟）包含以下字符串：

2020-03-04 10:58:00.533 7f29a8da3700 20 notification: 'bucketnotifications' on topic: 'bucketnotifications' and bucket: 'new-bucket' (unique topic: 'bucketnotifications') apply to event of type: 's3:ObjectCreated:Put'
2020-03-04 10:58:00.533 7f29a8da3700  1 ERROR: failed to create push endpoint: kafka://kafka-test-01:9092 due to: pubsub endpoint configuration error: unknown schema in: kafka://kafka-test-01:9092
2020-03-04 10:58:00.533 7f29a8da3700  5 req 188 0.248s s3:put_obj WARNING: publishing notification failed, with error: -22

但是 Apache Kafka 沒有創建新主題。

似乎 nautilus 版本中存在一個 kafka 架構不會檢查的錯誤。 您可以升級到支持此架構的15.2.0版或等待 nautilus 上的錯誤修復更新。
