ecs_task module support listing running tasks

  COMPONENT NAME

  ansible-modules-extras/cloud/amazon/ecs_task

ANSIBLE VERSION

2.3.0

OS / ENVIRONMENT

N/A

SUMMARY

module should support the list function aws ecs list-tasks --cluster default

this will enable us to gather current running tasks in a cluster and then act upon them.

looks like the framework is already there to list the tasks, just need a option rather then run, start and stop to list the array of returned tasks.

can you please elaborate on use cases?

[JoshuaSeidel]

@simplesteph we're using ansbile for the CD process into ECS. right now when i mark a task as inactive create a new revision and update the service, it can take between 5-20min for 2 containers to swap out. for some environments we need it to move faster, so being able to query with ansible for the current running tasks, having them match up to the old task revision and stopping. this will speed up the swap out process.

[simplesteph]

that's odd. make sure you're not using a load balance with a graceful timeout of 300 seconds, or that your containers have graceful stops. This definitely shouldn't be the behaviour. Also look into min and max percent for the ecs service to tweak how many containers can go down together.

But this alone doesn't warrant a module IMO. This looks like just some AWS config you need to tweak

@simplesteph As @JoshuaSeidel mentioned, there is already a function built for this.

    def list_tasks(self, cluster_name, service_name, status):
        response = self.ecs.list_tasks(
            cluster=cluster_name,
            family=service_name,
            desiredStatus=status
        )
        if len(response['taskArns'])>0:
            for c in response['taskArns']:
                if c.endswith(service_name):
                    return c
        return None

There's just no module parameter to call it directly. Am I understanding this right?

[simplesteph]

no worries you can do a PR and add a Param if that helps then!

This should probably be a new module ecs_task_facts rather than a new parameter for existing ecs_task module
