Ciris Aiven Kafka

Aiven Kafka support for Ciris.

Getting Started

To get started with sbt, simply add the following lines to your build.sbt file.

resolvers += Resolver.bintrayRepo("ovotech", "maven")

libraryDependencies += "com.ovoenergy" %% "ciris-aiven-kafka" % "1.1.1"

The library is published for Scala 2.12 and 2.13.

Usage

Simply import ciris.aiven.kafka._ and use aivenKafkaSetup to setup the key and trust stores.

import cats.effect.{Blocker, ExitCode, IO, IOApp}
import cats.implicits._
import ciris._
import ciris.aiven.kafka._

object Main extends IOApp {
  def run(args: List[String]): IO[ExitCode] =
    Blocker[IO].use { blocker =>
      aivenKafkaSetup(
        clientPrivateKey = env("CLIENT_PRIVATE_KEY"),
        clientCertificate = env("CLIENT_CERTIFICATE"),
        serviceCertificate = env("SERVICE_CERTIFICATE"),
        blocker = blocker
      ).load[IO]
    }.as(ExitCode.Success)
}

If the configuration loading was successful, aivenKafkaSetup will return an AivenKafkaSetup with the key and trust store locations, and their passwords. Temporary files and passwords are used and the files are set to be deleted automatically on exit. The key store is of type PKCS12 and the trust store is of type JKS.

AivenKafkaSetup provides properties: Map[String, String] with suitable consumer properties.

You can’t perform that action at this time.
