Hi! Any tips on how to supply userData to AWS ECS instances? I've got ecsCluster.createAutoScalingGroup() and when I pass userData in the launchConfiguration, the original ECS-specific userData is lost and my cluster doesn't start

Is this specifically about using the `awsx` library?

How are you passing the custom usersata?  I believe the awsx library provides a way to include custom runcmd and bootcmd sections but still keep all the ECS defaults - see <https://github.com/pulumi/pulumi-awsx/blob/master/nodejs/awsx/autoscaling/launchConfiguration.ts#L421|https://github.com/pulumi/pulumi-awsx/blob/master/nodejs/awsx/autoscaling/launchConfiguration.ts#L421>. 

<@UB3BGTV63> or <@U012FJB6PDY> - I'm stuck on the same thing. Looking for a little more clarity.

I see that I can add a new autoscaling group to a cluster, but is there some way to just pass `extraRuncmdLines` directly to a cluster? I don't see that option exposed in any `awsx` arguments object.

In my case, I'm trying to install a docker plugin at the time of creating the new EC2 instances.
