Score

Score is an open-source, platform-agnostic workload specification developed under the Cloud Native Computing Foundation (CNCF) Sandbox program. It provides a developer-centric YAML specification that enables teams to define application workloads once and deploy them across multiple container platforms including Docker Compose, Kubernetes, and cloud runtimes without environment-specific configuration drift. The score-spec organization provides reference CLI implementations (score-compose and score-k8s) that translate Score YAML into platform-specific manifests, eliminating YAML bloat and reducing cognitive load for platform engineering teams.

Score publishes 3 APIs on the APIs.io network. Tagged areas include Platform Engineering, Cloud Native, CNCF, Workload Specification, and Kubernetes.

The Score catalog on APIs.io includes 1 JSON-LD context.

Score’s developer surface includes documentation, engineering blog, and 6 more developer resources.

  description: The Score Specification (score.yaml) is a declarative, platform-agnostic workload definition format that captures
    containers, service ports, and resource dependencies in a single file. Reference CLI implementations (score-compose and
    score-k8s) translate Score files into Docker Compose manifests or Kubernetes manifests respectively. The specification
    supports metadata, container definitions with environment variables and volume mounts, service port exposure, health probes,
    and resource references using placeholder syntax.
