I’ve created an AWS launch template, but the autoscaling group can’t find it. Running this script as written fails to create either resource. I had to comment out the

asg

configuration, create the launch template separately, then go back and run the whole thing.

➜ cat __main__.py
import pulumi

from pulumi_aws import autoscaling, ec2

lt = ec2.LaunchTemplate('launch-template',
        image_id = 'ami-032509850cf9ee54e',
        instance_type = 't2.micro',
        )

asg = autoscaling.Group('autoscaling-group',
        launch_template = {'name': lt.id},
        min_size = 1,
        max_size = 4,
        )

pulumi.export('launch-template', lt.id),
pulumi.export('autoscaling group', asg.id),

After creating it separately, the launch template is available

➜ pulumi stack output launch-template
lt-01a8e3b45e7100203

But not to the autoscaling group apparently

➜ pulumi up -y
[...]
