// Availability Zone group in a Spot Instance request, all Spot Instances in the
// request are launched in the same Availability Zone. Instance proximity is
// maintained with this parameter, but the choice of Availability Zone is not. The
// group applies only to requests for Spot Instances of the same instance type. Any
// additional Spot Instance requests that are specified with the same Availability
// Zone group name are launched in that same Availability Zone, as long as at least
// one instance from the group is still active. If there is no active instance
// running in the Availability Zone group that you specify for a new Spot Instance
// request (all instances are terminated, the request is expired, or the maximum
// price you specified falls below current Spot price), then Amazon EC2 launches
// the instance in any Availability Zone where the constraint can be met.
// Consequently, the subsequent set of Spot Instances could be placed in a
// different zone from the original request, even if you specified the same
// Availability Zone group. Default: Instances are launched in any available
// Availability Zone.
AvailabilityZoneGroup *string
// Deprecated.
BlockDurationMinutes *int32
// Unique, case-sensitive identifier that you provide to ensure the idempotency of

// in the Amazon EC2 User Guide for Linux Instances.
ClientToken *string
// Checks whether you have the required permissions for the action, without
// actually making the request, and provides an error response. If you have the
// required permissions, the error response is DryRunOperation . Otherwise, it is
// UnauthorizedOperation .
DryRun *bool
// The maximum number of Spot Instances to launch. Default: 1
InstanceCount *int32
// The behavior when a Spot Instance is interrupted. The default is terminate .
InstanceInterruptionBehavior types.InstanceInterruptionBehavior
// The instance launch group. Launch groups are Spot Instances that launch
// together and terminate together. Default: Instances are launched and terminated
// individually
LaunchGroup *string
// The launch specification.
LaunchSpecification *types.RequestSpotLaunchSpecification
// The maximum price per unit hour that you are willing to pay for a Spot
// Instance. We do not recommend using this parameter because it can lead to
// increased interruptions. If you do not specify this parameter, you will pay the
// current Spot price. If you specify a maximum price, your instances will be
// interrupted more frequently than if you do not specify this parameter.
SpotPrice *string
// The key-value pair for tagging the Spot Instance request on creation. The value
// for ResourceType must be spot-instances-request , otherwise the Spot Instance
// request fails. To tag the Spot Instance request after it has been created, see
// CreateTags (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateTags.html)
// .
TagSpecifications []types.TagSpecification
// The Spot Instance request type. Default: one-time
Type types.SpotInstanceType
// The start date of the request. If this is a one-time request, the request
// becomes active at this date and time and remains active until all instances
// launch, the request expires, or the request is canceled. If the request is
// persistent, the request becomes active at this date and time and remains active
// until it expires or is canceled. The specified start date and time cannot be
// equal to the current date and time. You must specify a start date and time that
// occurs after the current date and time.
ValidFrom *time.Time
// The end date of the request, in UTC format (YYYY-MM-DDTHH:MM:SSZ).
// - For a persistent request, the request remains active until the ValidUntil
// date and time is reached. Otherwise, the request remains active until you cancel
// it.
// - For a one-time request, the request remains active until all instances
// launch, the request is canceled, or the ValidUntil date and time is reached.
