Plugins

Note: The plugin system is a new feature introduced since Falco 0.31.0. You can find more detail in the original proposal document.

This repository contains the Plugin Registry and the plugins officially maintained by the Falcosecurity organization. Plugins can be used to extend Falco and of applications using Falcosecurity libs. Please refer to the official documentation to better understand the plugin system's concepts and architecture.

Plugin Registry

The Registry contains metadata and information about every plugin known and recognized by the Falcosecurity organization. It lists plugins hosted either in this repository or in other repositories. These plugins are developed for Falco and made available to the community. Check out the sections below to know how to register your plugins and see plugins currently contained in the registry.

Registering a new Plugin

Registering your plugin inside the registry helps ensure that some technical constraints are respected, such as that a given ID is used by exactly one plugin with event source capability and allows plugin authors to coordinate about event source formats. Moreover, this is a great way to share your plugin project with the community and engage with it, thus gaining new users and increasing its visibility. We encourage you to register your plugin in this registry before publishing it. You can add your plugins in this registry regardless of where its source code is hosted (there's a url field for this specifically).

The registration process involves adding an entry about your plugin inside the registry.yaml file by creating a Pull Request in this repository. Please be mindful of a few constraints that are automatically checked and required for your plugin to be accepted:

The name field is mandatory and must be unique across all the plugins in the registry
(Sourcing Capability Only) The id field is mandatory and must be unique in the registry across all the plugins with event source capability
- See docs/plugin-ids.md for more information about plugin IDs
The plugin name must match this regular expression: ^[a-z]+[a-z0-9-_\-]*$ (however, its not recommended to use _ in the name, unless you are trying to match the name of a source or for particular reasons)
The source (Sourcing Capability Only) and sources (Extraction Capability Only) must match this regular expression: ^[a-z]+[a-z0-9_]*$
The url field should point to the plugin source code
The rules_url field should point to the default ruleset, if any

For reference, here's an example of an entry for a plugin with both event sourcing and field extraction capabilities:

- name: k8saudit
  description: ...

  maintainers:
    - name: The Falco Authors

Hosted Plugins

Another purpose of this repository is to host and maintain the plugins owned by the Falcosecurity organization. Each plugin is a standalone project and has its own directory, and they are all inside the plugins folder.

The main branch contains the most up-to-date state of development, and each plugin is regularly released. Please check our Release Process to know how plugins are released and how artifacts are distributed. Dev builds are published each time a Pull Request gets merged into main, whereas stable builds are released and published only when a new release gets tagged. You can find the published artifacts at https://download.falco.org/?prefix=plugins.

If you wish to contribute your plugin to the Falcosecurity organization, you just need to open a Pull Request to add it inside the plugins folder and to add it inside the registry. In order to be hosted in this repository, plugins must be licensed under the Apache 2.0 License.
