Service Environment Variables¶

This document provides a comprehensive reference for all environment variables used by SyRF services.

Note: Environment variables are now managed via the Schema-Driven Code Generation system. See Env-Mapping Code Generation for the architecture and How-To: Extend Env-Mapping Schema for adding new variables.

Source of Truth¶

All environment variables are defined in a single schema file:

src/charts/syrf-common/env-mapping.yaml

This schema generates:

Helm templates (_env-blocks.tpl) for .NET services
TypeScript interfaces for the web service
JSON configuration files for NGINX envsubst

Service	Total Env Vars	Prefix	Deployment Type
API	~70	`SYRF__`	.NET
project-management	~70	`SYRF__`	.NET
Quartz	~75	`SYRF__`	.NET

ConfigMap Support¶

Most non-secret values can be read from ConfigMaps instead of direct values. The pattern is:

# In values.yaml
mongoDb:
  configMapName: syrf-mongodb-config  # If set, reads from ConfigMap
  clusterAddress: "fallback-value"    # Used if configMapName not set

Supported ConfigMaps:

mongoDb.configMapName
postgres.configMapName
elastic.configMapName
rabbitMq.configMapName
s3.configMapName
ses.configMapName
auth0.configMapName
elasticApm.configMapName
googleSheets.configMapName
appSettings.configMapName
swaggerAuthConfig.configMapName
robApiSettings.configMapName

Web-Specific (Not Shared)¶

The web service uses SPA__ prefix and envsubst pattern, making it fundamentally different from .NET services. Web deployment should remain separate.
