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.

  name: Score Specification
  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.

- aid: score:score-compose
  name: score-compose
  description: score-compose is the reference Score implementation that translates Score YAML workload specifications into
    Docker Compose configuration files. It enables local development environments that mirror production workload definitions,
    supports resource provisioners for common dependencies like databases and message queues, and generates runnable Docker
    Compose files from a single score.yaml source.

  description: score-k8s is the reference Score implementation that translates Score YAML workload specifications into Kubernetes
    manifests including Deployments, Services, ConfigMaps, and Secrets. It supports Kubernetes resource provisioners, patch
    templates for customizing generated manifests, and enables consistent workload configuration from development to production
    on Kubernetes.
