本文介绍如何快速使用 Volcengine Python SDK 实现基础的 Kafka 实例资源管理流程，包括创建实例、创建 Topic 等操作。

前提条件 #

• 已安装 Volcengine Python SDK。更多信息，请参见安装 Python SDK。
• 已创建并获取火山引擎访问密钥 AccessKey。访问密钥 AccessKey 拥有所有 API 的全部权限。建议您通过 IAM 用户进行 API 相关操作和日常运维。使用 IAM 用户前，主账号需要为 IAM 用户授予消息队列 Kafka版相关资源和操作的权限。

示例代码 #

创建实例 #

通过 Volcengine Python SDK 调用消息队列 Kafka版 V2 API CreateInstance 的示例代码如下。

from __future__ import print_function
import volcenginesdkcore
from pprint import pprint
from volcenginesdkcore.rest import ApiException
import volcenginesdkkafka

if __name__ == '__main__':
    configuration = volcenginesdkcore.Configuration()
    configuration.ak = "Your AK"
    configuration.sk = "Your SK"
    configuration.region = "cn-beijing"
    # set default configuration
    volcenginesdkcore.Configuration.set_default(configuration)

    # use global default configuration
    api_instance = volcenginesdkkafka.KAFKAApi()

    try:
        resp = api_instance.create_instance(volcenginesdkkafka.CreateInstanceRequest(
            zone_id="cn-beijing-a",
            version="2.2.2",
            compute_spec="kafka.20xrate.hw",
            vpc_id="vpc-rs4yccs57e9sv0x57bf****",
            subnet_id="subnet-rrps5hvr1bswv0x58fp****",
            user_name="kafka2001",
            user_password="Test@123456",
            charge_info=volcenginesdkkafka.ChargeInfoForCreateInstanceInput(
                charge_type="PrePaid",
                auto_renew=True,
                period_unit="Month",
                period=1
            )
        ))
        pprint(resp)
    except ApiException as e:
        print("Exception when calling api: %s\n" % e)

查询实例列表 #

通过 Volcengine Python SDK 调用消息队列 Kafka版 V2 API DescribeInstances 的示例代码如下。

from __future__ import print_function
import volcenginesdkcore
from pprint import pprint
from volcenginesdkcore.rest import ApiException
import volcenginesdkkafka

if __name__ == '__main__':
    configuration = volcenginesdkcore.Configuration()
    configuration.ak = "Your AK"
    configuration.sk = "Your SK"
    configuration.region = "cn-beijing"
    # set default configuration
    volcenginesdkcore.Configuration.set_default(configuration)

    # use global default configuration
    api_instance = volcenginesdkkafka.KAFKAApi()

    try:
        resp = api_instance.describe_instances(volcenginesdkkafka.DescribeInstancesRequest(
            page_size=10,
            page_number=1,
        ))
        pprint(resp)
    except ApiException as e:
        print("Exception when calling api: %s\n" % e)

创建 Topic #

通过 Volcengine Python SDK 调用消息队列 Kafka版 V2 API CreateTopic 的示例代码如下。

from __future__ import print_function
import volcenginesdkcore
from pprint import pprint
from volcenginesdkcore.rest import ApiException
import volcenginesdkkafka

if __name__ == '__main__':
    configuration = volcenginesdkcore.Configuration()
    configuration.ak = "Your AK"
    configuration.sk = "Your SK"
    configuration.region = "cn-beijing"
    # set default configuration
    volcenginesdkcore.Configuration.set_default(configuration)

    # use global default configuration
    api_instance = volcenginesdkkafka.KAFKAApi()

    try:
        resp = api_instance.create_topic(volcenginesdkkafka.CreateTopicRequest(
            access_policies=[
                volcenginesdkkafka.AccessPolicyForCreateTopicInput(
                    access_policy="PubSub",
                    user_name="user123"
                )
            ],
            all_authority=False,
            description="describe",
            instance_id="kafka-cnngbnntswg1****",
            topic_name="mytopic123",
            replica_number=3,
            partition_number=3,
            parameters="{\"LogRetentionHours\":\"72\",\"MessageMaxByte\":\"10\",\"MinInsyncReplicaNumber\":\"2\"}"
        ))
        pprint(resp)
    except ApiException as e:
        print("Exception when calling api: %s\n" % e)
