Plugins

Fluent Bit comes with a variety of built-in plugins, and also supports loading external plugins at runtime. This feature is especially useful for loading Go or WebAssembly (Wasm) plugins that are built as shared object files (.so). Fluent Bit YAML configuration provides the following ways to load these external plugins:

Inline YAML

You can specify external plugins directly within your main YAML configuration file using the plugins section. Here's an example:

plugins:
  - /path/to/out_gstdout.so

service:
  log_level: info

pipeline:
  inputs:
    - name: random

  outputs:
    - name: gstdout
      match: '*'

YAML plugins file included using the plugins_file option

You can load external plugins from a separate YAML file by specifying the plugins_file option in the service section for better modularity.

To configure this:

service:
  log_level: info
  plugins_file: extra_plugins.yaml

pipeline:
  inputs:
    - name: random

  outputs:
    - name: gstdout
      match: '*'

In this setup, the extra_plugins.yaml file might contain the following plugins section:

plugins:
  - /other/path/to/out_gstdout.so
