Lab Steps
Ready for the real environment experience?
Description
With AWS CloudFormation, developers can spend less time managing resources and more time developing their applications. The reusable nature of CloudFormation templates allows developers to configure resources that can be deployed to different AWS regions or accounts.
AWS CloudFormation helper scripts can be called to initialize services on Amazon EC2 instances that are created as part of a stack.
In this lab, you will inspect and deploy an AWS CloudFormation template that utilizes the cfn-init and cfn-signal helper scripts to initialize an Apache server on an Amazon EC2 instance.
Learning Objectives
Upon completion of this intermediate-level lab, you will be able to:
- Configure an Apache server on an Amazon EC2 instance using cfn-init
- Signal to AWS CloudFormation when the instance configuration process has been completed using cfn-signal
