TrafficShiftConfig Struct
Configuration for traffic shift during progressive deployments.
Example
ts
declare const cluster: ecs.Cluster;
declare const taskDefinition: ecs.TaskDefinition;
declare const blueTargetGroup: elbv2.ApplicationTargetGroup;
declare const greenTargetGroup: elbv2.ApplicationTargetGroup;
declare const prodListenerRule: elbv2.ApplicationListenerRule;
const service = new ecs.FargateService(this, 'Service', {
cluster,
taskDefinition,
deploymentStrategy: ecs.DeploymentStrategy.LINEAR,
linearConfiguration: {
stepPercent: 10.0,
stepBakeTime: Duration.minutes(5),
},
});
const target = service.loadBalancerTarget({
containerName: 'web',
containerPort: 80,
alternateTarget: new ecs.AlternateTarget('AlternateTarget', {
alternateTargetGroup: greenTargetGroup,
productionListener: ecs.ListenerRuleConfiguration.applicationListenerRule(prodListenerRule),
}),
});
target.attachToApplicationTargetGroup(blueTargetGroup);
Properties
stepBakeTimeDurationstep_bake_timeDurationstepBakeTimeDurationStepBakeTimeDurationStepBakeTimeDuration#The duration to wait between traffic shifting steps.
Default: Duration.minutes(6) for linear, Duration.minutes(10) for canary
Valid values are 0 to 1440 minutes (24 hours).
The percentage of production traffic to shift in each step.
Default: 10.0 for linear, 5.0 for canary
- For linear deployment: multiples of 0.1 from 3.0 to 100.0
- For canary deployment: multiples of 0.1 from 0.1 to 100.0
