You have to manually scale the AutoScalingGroup, you say? :-)

More seriously, what's the barrier to configuring the ASG to grow and shrink automatically?

Heh, yeah basically you can create an asg, but ecs has no trigger to scale it based on the number of task containers you attempt to launch on the cluster....

There is a workaround, apparently, which is to create a custom metric but aws says this has not been tested to their knowledge... So any asg will be "static" implicitly...

[djb_hackernews]

That is definitely inaccurate. We have asgs that scale based on cpu load and custom cloudwatch metrics.

With ecs I can imagine a metric that keeps track of the number of tasks and hosts, or ports used or something. I think asg is the perfect tool to use to auto scale ecs clusters.

Ah, true... you could create custom metrics to trigger on... I was mentioning from the native ECS standpoint...

Also - all my information is only from the one day container session I attended at the pop-up last week... so I am certainly not an SME on ECS.
