#Configure Terraform to use your AWS account in one of the following ways.
#https://registry.terraform.io/providers/hashicorp/aws/latest/docs#authentication
#make sure to set AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables for the AWS provider.
#or define shared_credentials_file = "/path/to/aws_credentials" in the aws provider section.
#hardcoding the access_key and secret_key  in the aws provider section is also an option, but not recommanded.

#check the stored state file for Terraform version that generated the state.
# grep -e '"version"' -e '"terraform_version"' terraform.tfstate
