Developer guide for plugins
Is there a guide to getting started with building/testing the plugins, and how to add a new one?
An example from the Kubernetes project
Thanks!
Hi, You can read our blog post which describes how to write a plugin. https://falco.org/blog/extend-falco-inputs-with-a-plugin-the-basics/
We'll trying to adapt it as a tutorial in the docs for future.
Thank you, I was attempting to follow that guide but ran in to issues where the libc on my machine doesn't match the version included in the falco container image I was running. Perhaps we could update this guide to use the same container image used to build the falco images to prevent this sort of issue?
My current (bad) approach has been to do the following (or building an image based on falco), to avoid this issue
nerdctl run --rm -it -v$(pwd):/example:rw --entrypoint="/bin/bash" falcosecurity/falco -c 'apt update ; apt --fix-broken install -y ; apt install -y wget && wget https://go.dev/dl/go1.19.5.linux-amd64.tar.gz && tar -C /usr/local -xzf go1.19.5.linux-amd64.tar.gz && export PATH=$PATH:/usr/local/go/bin && cd /example && make clean && make && /usr/bin/falco -u -c /example/examples/running-locally/falco.yaml -r /example/examples/running-locally/falco_rules.yaml --list-plugins'
Thanks!

In the last months, our documentation has been revised and extended. I guess most of what the developers need is described at https://falco.org/docs/plugins/developers-guide/.
Do you think anything still needs to be added? :thinking:

It's still missing build details like which glibc to target, which go versions to use and other toolchain like things Instead of documenting it, it could be as simple as providing a container which can be used to generate compatible plugins? My approach to this can be seen in the command in https://github.com/falcosecurity/plugins/issues/225#issuecomment-1412405353
