    post:
      operationId: CreateDaemon
      summary: Create Daemon
      description: Creates a new daemon in the specified cluster and capacity providers. A daemon deploys cross-cutting software agents such as security monitoring, telemetry, and logging independently across your Amazon ECS infrastructure. Amazon ECS deploys exactly one daemon task on each container instance of the specified capacity providers. When a container instance registers with the cluster, Amazon ECS automatically starts daemon tasks. Amazon ECS starts a daemon task before scheduling other tasks. Daemons are essential for instance health - if a daemon task stops, Amazon ECS automatically drains and replaces that container instance. ECS Managed Daemons is only supported for Amazon ECS Managed Instances Capacity Providers.

      description: Updates the specified daemon. When you update a daemon, a new deployment is triggered that progressively rolls out the changes to the container instances associated with the daemon's capacity providers. For more information, see Daemon deployments in the Amazon Elastic Container Service Developer Guide. Amazon ECS drains existing container instances and provisions new instances with the updated daemon. Amazon ECS automatically launches replacement tasks for your services. Updating a daemon triggers a rolling deployment that drains and replaces container instances. Plan updates during maintenance windows to minimize impact on running services. ECS Managed Daemons is only supported for Amazon ECS Managed Instances Capacity Providers.
