Struct PrometheusTemplateRenderingService 

pub struct PrometheusTemplateRenderingService { /* private fields */ }

Service for rendering Prometheus configuration templates

This service encapsulates the logic for rendering prometheus.yml configuration files. It’s designed to be shared across command handlers and steps that need to prepare Prometheus configuration.

Implementations

impl PrometheusTemplateRenderingService

pub fn from_paths( templates_dir: PathBuf, build_dir: PathBuf, clock: Arc<dyn Clock>, ) -> Self

Build a PrometheusTemplateRenderingService from environment paths

Arguments

• templates_dir - Directory containing the source templates
• build_dir - Directory where rendered templates will be written
• clock - The clock for generating timestamps

Returns

Returns a configured PrometheusTemplateRenderingService ready for template rendering

pub fn render( &self, prometheus_config: Option<&PrometheusConfig>, tracker_config: &TrackerConfig, ) -> Result<Option<PathBuf>, PrometheusTemplateRenderingServiceError>

Render Prometheus configuration templates

This renders the prometheus.yml configuration file to the build directory. Returns None if Prometheus is not configured.

Arguments

• prometheus_config - Prometheus configuration from user inputs (optional)
• tracker_config - Tracker configuration (needed for API token and port)

Returns

Returns the path to the rendered Prometheus build directory, or None if not configured

Errors

Returns PrometheusTemplateRenderingServiceError::RenderingFailed if template rendering fails.
