Technology Stack

VRO software leverages a wide range of tools and technologies, categorized by their purpose within the stack:

Java: Most of the project is built using the Spring Framework.
Python: Domain services (partner team projects) are primarily written in Python.
Ruby: One domain service is currently written in Ruby.

RabbitMQ: Serves as the primary communication bus between microservices, using AMQP architecture.
Gradle: Utilized for build automation. Refer to the buildSrc folder for details.
Docker: Extensively used for local development and deployments.
- Note: In most cases, Docker Desktop is not provided. Colima is recommended as an alternative container runtime.
Postgres: AWS RDS Postgres is employed for database services, managed through Helm charts.
Redis: Currently in the process of being removed from the stack.
Kubernetes: VRO’s DevOps operations are supported by LHDI infrastructure.
ArgoCD: Used for deployment management (see this issue).

VRO also utilizes these key repositories for project management and deployments:

VRO Public Repo: Main repository for the VRO project.
VRO Internal Repo: Used for running SecRel scans.
ArgoCD Repo: Contains the ArgoCD URL for viewing deployments.
VRO Skeleton: VRO Python starter project. Eventually, Java and Ruby skeleton projects will be added.
