## AppSpec file reference

* **Note**\
  The AppSpec file for an EC2/On-Premises deployment must be named `appspec.yml` or `appspec.yaml`, unless you are performing a local deployment. For more information, see [Create a local deployment](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_code_deploy/deployments-local.md#deployments-local-deploy).
* **Note**\
  The tar and compressed tar archive file formats (.tar and .tar.gz) are not supported for Windows Server instances.

## AWS CloudFormation template reference

* **Note**\
  AWS CloudFormation hooks are part of the AWS CloudFormation components for AWS and are different from CodeDeploy lifecycle event hooks.

## Resource kit reference

* **Note**\
  To access the Amazon S3 bucket in the Asia Pacific (Hong Kong) Region, you must enable the region in your AWS account. For more information, see [Managing AWS Regions](https://docs.aws.amazon.com/general/latest/gr/rande-manage.html#rande-manage-enable).
* **Note**\
  The files in each bucket are designed to work with resources in the corresponding region.
*
* **Note**\
  Be sure to use the period (`.`) near the end. This downloads the file to your current directory.

## Limits

* **Note**\
  You can [request a limit increase](https://console.aws.amazon.com/support/home#/case/create%3FissueType=service-limit-increase) for the CodeDeploy limits listed in [AWS service limits](https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html#limits_codedeploy) in the *Amazon Web Services General Reference* . You cannot increase the limit on the number of hours a deployment can run.
