AWS ECS Error when running task: No Container Instances were found in your cluster

Question

Im trying to deploy a docker container image to AWS using ECS, but the EC2 instance is not being created. I have scoured the internet

Answer 1

Another possible cause that I ran into was updating my ECS cluster AMI to an "Amazon Linux 2" AMI instead of an "Amazon Linux AMI", which caused my EC2 user_data launch script to not work.
