Auto-Discovering Infrastructure Dependencies Across 10 Ecosystems

Short summary

Auto-discovering infrastructure dependencies across multiple ecosystems requires parsing dependencies from source files, but each ecosystem (Terraform, Docker, Kubernetes, Helm, Python, Go, npm, Ansible) declares them differently with unique syntax variations, variable interpolation, and registry handling. The implementation pattern—enumerate repos, parse files, resolve references, build a dependency graph—is straightforward; the complexity lies in handling ecosystem-specific edge cases like build-time arguments and distinguishing public from internal registries.

• •Dependencies are already declared in source files across a dozen formats and ecosystems, requiring specialized parsers
• •Each ecosystem has unique challenges: Terraform modules support multiple URL formats and variable interpolation, Dockerfiles use ARG-based parameterization, CI configs reference templates differently
• •A production system needs fallback strategies for unresolved variables and must distinguish internal dependencies from public packages
