  title: Amazon GameLift Deploy Build to a Fleet
  summary: Register a game build, create a fleet from it, and wait for the fleet to become ACTIVE.
  description: >-
    The core Amazon GameLift hosting setup flow. The workflow creates a new
    build resource for your game server binaries, deploys that build onto a new
    EC2 fleet, and then polls the fleet's attributes until it reaches ACTIVE
    status and can accept game sessions. Each step spells out its AWS JSON
    protocol request inline, including the X-Amz-Target header, so the flow can
    be read and executed without opening the underlying OpenAPI description.

  summary: Create a build, create a fleet from it, and poll until the fleet is ACTIVE.
  description: >-
    Creates a build resource, launches a fleet that deploys the build on EC2
    instances, and repeatedly describes the fleet until Amazon GameLift reports
    it in ACTIVE status.

  steps:
  - stepId: createBuild
    description: >-
      Create a new build resource for the game server binaries. A new build is
      placed in INITIALIZED status and must reach READY before a fleet can use
      it.
