  title: Amazon SageMaker Provision Notebook Instance
  summary: Create a SageMaker notebook instance and poll it until it is in service.
  description: >-
    A common SageMaker development setup flow. The workflow launches a managed
    Jupyter notebook instance with the requested instance type and IAM role,
    then describes the instance and loops while its status remains Pending,
    continuing once the instance reaches a terminal state such as InService or
    Failed. The connection URL is captured for the caller. Each step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
