Defines the traffic routing strategy during an endpoint deployment to shift traffic from the old fleet to the new fleet.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
JSON
{
"CanarySize" : CapacitySize,
"LinearStepSize" : CapacitySize,
"Type" : String,
"WaitIntervalInSeconds" : Integer
}
YAML
CanarySize:
CapacitySize
LinearStepSize:
CapacitySize
Type: String
WaitIntervalInSeconds: Integer
Properties
CanarySize-
Batch size for the first step to turn on traffic on the new endpoint fleet.
Valuemust be less than or equal to 50% of the variant's total instance count.Required: No
Type: CapacitySize
Update requires: No interruption
LinearStepSize-
Batch size for each step to turn on traffic on the new endpoint fleet.
Valuemust be 10-50% of the variant's total instance count.Required: No
Type: CapacitySize
Update requires: No interruption
Type-
Traffic routing strategy type.
-
ALL_AT_ONCE: Endpoint traffic shifts to the new fleet in a single step. -
CANARY: Endpoint traffic shifts to the new fleet in two steps. The first step is the canary, which is a small portion of the traffic. The second step is the remainder of the traffic. -
LINEAR: Endpoint traffic shifts to the new fleet in n steps of a configurable size.
Required: Yes
Type: String
Allowed values:
ALL_AT_ONCE | CANARY | LINEARUpdate requires: No interruption
-
WaitIntervalInSeconds-
The waiting time (in seconds) between incremental steps to turn on traffic on the new endpoint fleet.
Required: No
Type: Integer
