  Testcontainers is an open-source library ecosystem that provides throwaway,
  lightweight Docker container instances for integration testing across more than
  a dozen programming languages including Java, Go, .NET, Node.js, and Python.
  Developers define real test dependencies — databases, message brokers, browsers
  — as code rather than relying on mocks or shared environments. Testcontainers
  Cloud extends the library to a hosted container runtime service that runs
  container-backed tests in the cloud, eliminating the need for a local Docker
  daemon and enabling parallel execution in CI/CD pipelines. The platform
  authenticates via a TC_CLOUD_TOKEN environment variable or service account
  token, and usage is metered in Worker Minutes bundled with Docker Pro, Team,
  and Business subscriptions.

    description: >-
      The Testcontainers Cloud Agent API enables CI/CD pipelines and desktop
      environments to allocate hosted Docker container workers in the cloud.
      Authentication is performed via TC_CLOUD_TOKEN service account tokens;
      usage is metered in Worker Minutes and configurable through environment
      variables and agent command-line flags.
