Im trying to get a file in cloudformation to generate in an ec2 instance and cant seem to see it on the ec2 instance

Question

currently I try to simply spin up an ec2 instance to show myfile2.txt in the tmp folder currently the cloud formation launches. but no file. I have tried working around in the command line and check the logs but I don't see what the issue is I've been having trouble with AWS::CloudFormation::Init: for a while and was wondering if anyone had any suggestions??

This is a just simple exercise that is part of a greater project.

It's not clear if you're running cfn-init command or not. Ideally your userdata section would have a command cfn-init which in turn would invoke the configsets defined under Init key. Please check the sample snippet below.

UserData: !Base64 
  'Fn::Join':
    - ''
    - - |
        #!/bin/bash -xe
      - |
        # Install the files and packages from the metadata
      - '/opt/aws/bin/cfn-init -v '
      - '         --stack '
      - !Ref 'AWS::StackName'
      - '         --resource WebServerInstance '
      - '         --configsets InstallAndRun '
      - '         --region '
      - !Ref 'AWS::Region'
      - |+
