Setting directory owner and permission with appspec.yml through Amazon Web Service CodeDeploy

I'm deploying a Node.js application through Codeship using the CodeDeploy AWS deployment system.

I am making use of the appspec.yml file to set the owner and permissions of one of the deployed directory.

I want to allow read/write for any files that will be created in a specified folder of the deployment. Files will be created by the web application once it starts running.

Currently my appspec.yml contains the following:

version: 0.0
os: linux
files:
  - source: /
    destination: /var/www/APPLICATION_NAME
permissions:
  - object: /var/www/APPLICATION_NAME/tmpfiles
    mode: 644
    owner: ec2-user
    type:
      - directory
