Need to make lifecycle changes a variable about terraform-aws-ec2-instance

[antonbabenko]

Can you please explain why do you need to ignore changes in arguments like user_data, ami, etc?

[keepercj]

AMI is needed as we have weekly images created and shared with our AWS account and a data resource to lookup and grab the new one. User_data is needed because sometimes we have to update options in our cloudinit script and build extra nodes, but this breaks multiple host builds. I.E. We've deployed 5 nodes with 1 version of a cloud init, then want to go back and add 5 more nodes with different options. It accounts for cloudinit config drifts. In any event there should be a way to remove/add lifecycle changes.

[antonbabenko]

There is no way to use variables in lifecycle block of individual resources and this use-case is not something I think should be in this module.

I recommend you to fork this module and customize for your use case, or consider using terraform-aws-autoscaling module and adjust desired capacity there from 0 to 5.
