Walkthrough

Documentation update for the Docker events input plugin standardizing configuration parameter names from PascalCase to snake_case (e.g., Unix_Path → unix_path), adding introductory sections with command-line and configuration examples, updating external documentation links, and restructuring the configuration table format.

Changes

Cohort / File(s) Summary
Docker events documentation
pipeline/inputs/docker-events.md
Updated external Docker docs link from engine events to system events reference. Converted all configuration keys from PascalCase to snake_case (Unix_Path, Buffer_Size, Parser, Key, Reconnect.Retry_limits, Reconnect.Retry_interval, Threaded). Added "Get started" section with command-line example and expanded YAML/Fluent Bit configuration code blocks. Updated table structure, defaults, and descriptions to align with new naming convention.

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~5 minutes

  • Single file affected with primarily repetitive naming standardization across configuration parameters
  • Documentation-only changes with no code logic to verify
  • Consistent pattern application (PascalCase → snake_case conversion) throughout

Poem

🐰 Hop, hop, hooray! The docs now gleam so bright,
Configuration keys aligned, from Pascal to snake—what a sight!
Examples dance in YAML's gentle flow,
Docker events documented—let the pipelines go! 🚀

9-17: Verify configuration parameters are complete and accurate.

The configuration table has been standardized to snake_case. Confirm that:

  1. All supported parameters are documented
  2. The parameter names match the actual plugin implementation
  3. Default values are correct and current

Consider searching the plugin implementation to validate that the documented parameters align with the code.


19-61: Validate example code and plugin naming.

The new "Get started" section provides helpful command-line and configuration examples. Verify that:

  1. The plugin input name is correctly referenced as docker_events in all examples
  2. The examples accurately reflect current Fluent Bit syntax and behavior
  3. The example outputs with Match: '*' appropriately route all Docker events

You may want to test these examples to ensure they work as documented. Also confirm the plugin name matches the actual Fluent Bit plugin identifier.


1-61: Verify this documentation reflects current plugin behavior (PascalCase vs snake_case).

The documentation now standardizes all configuration parameters to snake_case (e.g., unix_path instead of Unix_Path). Confirm whether:

  1. This documentation is fixing outdated/incorrect parameter names
  2. The actual plugin has been updated to use snake_case
  3. Users with existing configurations using PascalCase need migration guidance

If this represents an actual parameter name change in the plugin, consider adding a migration note or deprecation notice for users upgrading from previous versions.
