Q: Developers on your teams struggle with 800-line Helm values.yaml files and environment-specific Kubernetes manifests. How do you implement Score (score.dev) to provide a developer-centric specification that translates cleanly to Docker Compose locally and Helm/ArgoCD in cloud clusters?
Decoupling developer workload definitions from target environment infrastructure using the CNCF Score specification.

Author Developer-Centric score.yaml Specification
Developers declare container requirements and abstract resource dependencies in under 30 lines of YAML, completely independent of Kubernetes namespaces, ingress classes, or AWS ARNs.

type: postgresConfigure Platform Dynamic Resource Resolvers
The platform team defines resource provisioners. Locally, `score-compose` spins up an ephemeral Postgres container in docker-compose. In production, the translator resolves `${resources.db.host}` to an AWS RDS instance provisioned via Crossplane.
# Local translation:
score-compose generate score.yaml --output-file docker-compose.yaml
# Cloud translation:
score-helm generate score.yaml --values-file values-prod.yaml -o helm-chart/Validate Environment Parity in CI/CD Pipelines
Validate the `score.yaml` in pre-commit and CI hooks using `score-k8s`. Ensure developers never commit environment-specific IP addresses, ingress annotations, or static secret credentials.
- Replace complex Helm values files with lightweight, environment-agnostic score.yaml manifests.
- Use score-compose for zero-overhead local development and score-helm for production GitOps delivery.
- Platform teams maintain centralized resource provisioners mapping abstract resources (like postgres) to cloud infrastructure.
