Fluent bit docker images are not compatible with Apple M2 chips. about cloud-native-spring-in-action

Hi @ketankvishwakarma, thanks for reporting this issue. The Loki-flavoured image of Fluent Bit used in the book is built for AMD64 architectures. It can still run on Apple Silicon computers thanks to Docker Desktop (which uses the proper virtualisation to make that work), but you get a warning about it. As you noticed, logs are correctly scraped by Fluent Bit, sent to Loki, and browsable from Grafana even on an Apple M2 computer.

For the purpose of the examples in the book, the warning can be ignored. If you'd like to get rid of it, you can update the docker-compose.yml file to configure explicitly that the FluentBit image requires an AMD64 architecture. Docker Desktop, on top of Apple Rosetta, will make it work.

version: "3.8"
services:
    ...
    fluent-bit:
        image: grafana/fluent-bit-plugin-loki:2.6.1-amd64
        container_name: fluent-bit
        platform: linux/amd64
    ...

Unfortunately, Grafana doesn't provide a grafana/fluent-bit-plugin-loki image for ARM64 architectures yet (issue here).

I'm currently working on a setup that uses the full Grafana stack (with Promtail instead of Fluent Bit) and I plan to publish it soon on a new repo on my GitHub together with a bunch of dashboards I've been designing for several Spring Boot scenarios. I'll let you know when that is published.
