  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.

    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.

      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.

      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.
