Add WebUI

[birdayz]

Kaf should have a WebUI.

I tend towards the following setup:

• kaf ui starts a local webserver on port XYZ
• grpc & grpc-web is used to communicate from VueJS (or something more lightweight) frontend
• since we add a grpc API, this can be used to run kaf in a k8s cluster and invoke commands from local - without using e.g. telepresence to reach brokers in a cluster.

TODO

• Implement Subscribe() for each Resource (Topic, Group?), so changes are reflected instantly

this will not happen in the near future probably. it's something i want to do, but adding further concrete CLI commands has priority over exposing the same existing features on a different frontend.

Update: For everyone who's interested: i managed to find some spare time to work on this. it's going to happen :)

Sneak preview:

the only thing to do is running kaf serve and browsing to http://localhost:8081. It's implemented via a gRPC endpoint and a VueJS app using grpc-web to fetch the data. A lot of work needs to be done, but we'll see some major updates on this in the next weeks.

Hello, take a look at https://github.com/mikekonan/kafka-ui I believe you could reuse/enhance some parts of it

Also take a look at https://github.com/provectus/kafka-ui - the web UI has to be hosted somewhere which is a bummer for people who just want to run a local tool.
