manual installation of kafka extension failed

[nachoge]

Hi, I'm following your docs on how to install the kafka extension but nothing happends...

following: https://github.com/Azure/azure-functions-kafka-extension/tree/master/samples

I'm working with centos 8 anf java 11 right now having installed azure-cli-2.16.0-1.el7.x86_64 dotnet-sdk-5.0-5.0.100_rc.2.20479.15-1.x86_64 dotnet-runtime-5.0-5.0.0-0.8.0201202git337413b.el8_3.x86_64 dotnet-host-5.0.0-0.8.0201202git337413b.el8_3.x86_64 dotnet-runtime-deps-5.0-5.0.0-0.1.rc.2.20475.5.x86_64 dotnet-targeting-pack-5.0-5.0.0-0.1.rc.2.20475.5.x86_64 dotnet-hostfxr-5.0-5.0.0-0.8.0201202git337413b.el8_3.x86_64 dotnet-apphost-pack-5.0-5.0.0-0.1.rc.2.20475.5.x86_64

aspnetcore-runtime-5.0-5.0.0-0.8.0201202git337413b.el8_3.x86_64 aspnetcore-targeting-pack-5.0-5.0.0-0.1.rc.2.20475.17.x86_64

when I issue this command: func extensions install --package Microsoft.Azure.WebJobs.Extensions.Kafka --version 3.2.1

this is the output No action performed. Extension bundle is configured in /home/igarcia....../host.json

the host.json remains the same { "version": "2.0", "extensionBundle": { "id": "Microsoft.Azure.Functions.ExtensionBundle", "version": "[1.*, 2.0.0)" } }

and no librdkafka exists

any help appreciate

thanks

Hello @nachoge Could you try to remove "extensionBundle" part? then try func install again? Kafka extension is not included by the extension bundle.

This is an example (this is for Debian/Ubuntu based, however, you can refer the host.json.

host.json { "version": "2.0" }

Hi @nachoge You look using .net 5 sdk. However, Azure Functions doesn't support it (currently). Could you try 3.1 instead? Also you can refer the Dockerfile (for Debian) in case you've got other errors.

These Dockerfile might be a good example.

• java11-appservice.Dockerfile
• java11-core-tools.Dockerfile

Hi @TsuyoshiUshio,

Thanks I will give you a feedback as soon as possible!

@TsuyoshiUshio Is .NET 5 supported by this library now since AF support it? Is there a sample?

[TsuyoshiUshio]

Yeah. Looks so. https://github.com/Azure/azure-functions-dotnet-worker/blob/main/samples/Extensions/Kafka/KafkaFunction.cs

Looks like this issue is more related to .Net version support so closing this issue for now as Az Func doesn't support .Net5 version
