Mistake CF Template
As writing in other review, this product do not work properly.
First: you are forced to create an account (thanks, now I've 3 Elastic Cloud account, and you can't delete it)
Second: CloudFormation Launch Template do not work properly (multiple reason)
I spent 1 hour to try debugging yaml Launch Template (first time for me) and I waste my time.
As a result, I will buy a EC2 instance and run myself ES on docker...
Waste of time & money - don't try this. Read other comments & find another way to run ES
PS: 1 star because I couldn't put 0 star
