I've the following code

Copy code

const asgEventsTopic = new aws.sns.Topic("asg-events-topic")

asgEventsTopic.onEvent("ci-cd-scale-in", async ev =>{
    console.log("Processing " + ev);
})

const runnerAsg = new aws.autoscaling.Group("ci-cd-runner-asg", {
    name: "ci-cd-runner-asg",
    desiredCapacity: 2,
    maxSize: 2,
    minSize: 1,
    healthCheckGracePeriod: 300,
    healthCheckType: "EC2",
    launchTemplate: {
        id: launchTemplate.id,
        version: `$Latest`,
    },
    vpcZoneIdentifiers: vpc.privateSubnetIds,
    initialLifecycleHooks: [{
        name: "asg-events-hook",
        defaultResult: "CONTINUE",
        lifecycleTransition: "autoscaling:EC2_INSTANCE_TERMINATING",
        notificationTargetArn: asgEventsTopic.arn
    }]
});

the sns topic is assigned as a

notificationTargetArn

to the ASG. I noticed during delete the topic subscription is deleted before the ASG. If it were the other way around, ASG deleted prior to topic subscription, deleting ASG would fire lifecycle transtion events for the EC2 hosts. In thread, I'm posting the output of

pulumi delete

bug may be / am I missing something?
