The aws_spot_instance resource enables Cluster to create customized spot
instance groups.
Provision a spot instance in AWS to reduce the cost of instances. Spot
instance availability is not guaranteed. Therefore, it is recommended to use
aws_spot_instance_request for additional worker nodes and not for
mission-critical nodes like managers and registry.
The following is a basic example:
resource:
aws_spot_instance:
workers:
instance_type: "t2.xlarge"
os: "Ubuntu 18.04"
price: 0.25
quantity: "3"
aws_spot_instance supports all of the settings for `` aws_instance
with the addition of the following
| Setting | Type | Default | Description |
|---|---|---|---|
price |
Float | None | Maximum price to bid on the spot instance |
