[aws-events-targets] Support tagging when starting a Fargate task from CloudWatch Events

[zulhfreelancer]

I saw this issue on aws/containers-roadmap and it's exactly the problem I'm facing now. I'm using EcsTask and EcsTaskProps to schedule Fargate tasks using CloudWatch Events rule. Since the scheduled task will run without ECS service, I can't use propagateTags or propagateTaskTagsFrom props.

Use Case

Mainly for billing. By having specific tags, I can use them in AWS Cost Explorer to see the cost breakdown for my scheduled tasks vs normal tasks (i.e. web containers).

Proposed Solution

Something like this would be great:

import events = require("@aws-cdk/aws-events");
import event_targets = require("@aws-cdk/aws-events-targets");

const rule = new events.Rule(this, "theRule", {
    enabled: true,
    // code omitted for brevity
});

rule.addTarget(
    new event_targets.EcsTask({
        // code omitted for brevity
        taskTags: [
            {
                key: "project",
                value: "my-cdk-project"
            },
            {
                key: "team",
                value: "team-a"
            }
        ]
    })
);

Adding support for propagateTags would be great too! (As of now, CloudFormation doesn't seem to have this property)

Potentially related to aws-cloudformation/cloudformation-coverage-roadmap#394

Any updates on this? Is there a known workaround to propagate the tags to an EcsRunTask started by a statemachine / event rule / schedule?

I'm also interested in updates to this issue. It seems from aws-cloudformation/cloudformation-coverage-roadmap#394 that it should be supported by CloudFormation now, but I can't see any options in cdk. I'm trying to add tags to a ScheduledFargateTask.

I solved it via #14553 (comment), maybe this is an option for you too
