Struct DockerComposeTemplateRenderingService 

pub struct DockerComposeTemplateRenderingService { /* private fields */ }

Service for rendering Docker Compose templates

This service encapsulates the complex logic for building Docker Compose contexts including:

• Database variant selection (SQLite vs MySQL)
• Topology computation (which services are enabled)
• Optional service configuration (Prometheus, Grafana, Backup, Caddy)
• Grafana environment context
• MySQL setup configuration

Implementations

impl DockerComposeTemplateRenderingService

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

Create a new service with explicit dependencies

Arguments

• templates_dir - Directory containing template source files
• build_dir - Directory where rendered templates will be written
• clock - Clock service for timestamps

pub async fn render( &self, user_inputs: &UserInputs, admin_token: &str, ) -> Result<PathBuf, DockerComposeTemplateRenderingServiceError>

Render Docker Compose templates with full context building

This method builds the complete Docker Compose context from user inputs, including database-specific configuration, topology computation, and optional service integration.

Arguments

• user_inputs - Complete user configuration
• admin_token - Tracker admin token

Returns

Path to the rendered docker-compose build directory

Errors

Returns error if template rendering fails
