Configuration

The config plugin is an essential component in RoadRunner, responsible for parsing configuration files and environment variables. It serves as a central hub for managing configurations for the plugins and RoadRunner server itself.

Configuration File Structure

The RoadRunner configuration file should be formatted using YAML or JSON. Each configuration file must include a version at the top, indicating the format's version. The currently supported configuration version is version 3.

The configuration version is not synonymous with the RoadRunner (RR) version. The configuration version and RR version have separate versioning systems.

Example of a YAML configuration file:

.rr.yaml

version: '3'

# ... other config values

Version numbers are strings, not numbers. For example, version: "3" is correct, but version: 3 is not.

Tips

1. By default, .rr.yaml used as the configuration, located in the same directory with RR binary.
