Configure DependencyTrack with Terraform

Source: Dev.to

Why DependencyTrack Matters

Dependency management and Software Bill of Materials (SBOMs) are more important than ever. With the upcoming EU Cyber Resilience Act, they are becoming a legal mandate for many organizations. Beyond compliance, using SBOMs together with reproducible builds as your “source of truth” for dependencies is a solid security practice.

DependencyTrack (an OWASP project) helps you manage SBOMs and audit vulnerabilities of used dependencies. It is organized around projects. While a project type (e.g., Application, Container Image) is technically just a label, how you structure them matters.

Recommended Project Structure

Create a standalone project for each component of your application (e.g., separate projects for your frontend and backend). This separation provides:

• Contextual Auditing: Vulnerabilities are easier to triage when you know exactly which layer they affect.
• Statistical Transparency: Clearer metrics on component counts per service.
• Hierarchical Organization: Better integration with Collection Projects.

Collection Projects

Collection Projects let you organize projects in a tree‑based structure. For an app My Calendar you could create a parent collection project that aggregates data from its child projects (Frontend and Backend). Collection projects don’t contain direct components; they aggregate them from their children based on configuration.

This approach scales well for multiple apps with components deployed across different environments (dev, prod, etc.):

- My-Shop
  - Basket Service
    - Basket Service (Dev)
      - Basket Service Frontend (Dev)
      - Basket Service Backend (Prod)
    - Basket Service (Prod)
      - Basket Service Frontend (Dev)
      - Basket Service Frontend (Prod)
  - Payment Service
    ...

Automating Setup with Terraform

Manually creating dozens of nested projects is tedious. The DependencyTrack Terraform Provider automates the creation of nested structures, teams, permissions, and LDAP mappings.

If you prefer a “Product Group” approach—grouping services like Payment, Basket, and Inventory into a single functional unit—use the community module:

Treat DependencyTrack Configuration as Code

Even without the module, managing DependencyTrack via Terraform brings several benefits:

• Auditability: Every change is tracked in version control.
• Disaster Recovery: Easily restore your entire project structure if a database is lost.
• Living Documentation: Your HCL files explain the setup better than a “lost” colleague ever could.
