[cloudformation] Error parsing parameter '--template-body': Unable to load paramfile

[santosh]

I am following basic cloudformation tutorial. This is my template contents:

AWSTemplateFormatVersion: 2010-09-09
Description: A simple EC2 instance
Resources:
  MyEC2Instance:
    Type: 'AWS::EC2::Instance'
    Properties:
      ImageId: ami-006d3995d3a6b963b
      InstanceType: t2.micro
      KeyName: dev-on-ec2

A key with that name already exists in the AWS account.

I am running this command:

aws cloudformation create-stack --stack-name ec2-demo --template-body file:///tmp/cfn/ec2.yaml

Location of the template is: /tmp/cfn/ec2.yaml

I am getting this error:

Error parsing parameter '--template-body': Unable to load paramfile file:///tmp/cfn/ec2.yaml: [Errno 2] No such file or directory: '/tmp/cfn/ec2.yaml'

Hi @santosh there's an existing feature request related to this: #2275. Per this comment YAML isn't currently supported in the command line but there are some workarounds in the comments such as #2275 (comment) that you could try.

Looking at the age of the issue it feels like it will take another 5 years to be implemented. I'll better upload it to S3 and try to proceed from there.
