Shared Configurations
The shared/ directory contains configurations that are shared across all services:
- PostgreSQL (
postgres.yml): Contains database credentials and service-specific database names (e.g.,service-name-db). - RabbitMQ (
rabbitmq.yml): Defines two queues per service (main queue and dead letter queue). - Elasticsearch (
elasticsearch.yml): Configures unique indices for each service (e.g.,service-name-{env:local}). - Redis (
redis.yml): Shared Redis configurations. - Monitoring (
monitoring.yml): Includes configurations for Grafana, Loki, and Prometheus. - Vault (
vault.yml): HashiCorp Vault configurations for secure secret management.
Environment-Specific Configurations
Each service has the following environment-specific configuration files:
application-local.yml: Local development environment.application-uat.yml: User Acceptance Testing (UAT) environment.application-prod.yml: Production environment.
How to Use
- Spring Cloud Config Server: Point your Spring Cloud Config Server to this repository to serve configurations to your microservices.
- Environment Variables: Use environment variables to override sensitive values (e.g., database credentials, API keys).
- Shared Configurations: Leverage the
shared/directory for common configurations across services.
Monitoring and Observability
The repository includes configurations for monitoring and observability tools:
- Grafana: Dashboard configurations for visualizing metrics.
- Loki: Centralized logging configurations.
- Prometheus: Metrics scraping configurations.
Security
- HashiCorp Vault: Securely manage secrets such as database credentials, API keys, and tokens.
Contributing
Feel free to contribute to this repository by adding new configurations or improving existing ones. Ensure that all changes are tested in the appropriate environments.
This repository is a critical part of the infrastructure and ensures consistent and centralized configuration management for all microservices.
