我想使用 docker-compose 创建一个本地 kafka 设置,该设置非常接近地复制融合云中的安全 kafka 设置。
我在 Confluent Cloud 中拥有的集群可以使用
c = Consumer(
{
"bootstrap.servers": "broker_url",
"sasl.mechanism": "PLAIN",
"security.protocol": "SASL_SSL",
"sasl.username": "key",
"sasl.password": "secret",
"group.id": "consumer-name",
}
)
但是我无法在本地创建具有相同配置并且可以使用相同代码连接到的 docker-compose.yml。

这是我在本地 docker-compose 文件方面的内容,但它不起作用这是我尝试使用相同代码连接时遇到的错误
