Files

• tomcat.yml: This is the CloudFormation template that defines the resources for the stack. It creates an EC2 instance and a security group. It also installs and configures Tomcat, along with its dependencies such as Java. In addition, it compiles a small test application and deploys it on Tomcat for execution.

• deployStack.sh: This script deploys the CloudFormation stack using the AWS CLI. It assumes that the AWS CLI is installed and configured, and that the stack name is 'Tomcat10'.

• deleteStack.sh: This script deletes the CloudFormation stack using the AWS CLI. It also assumes that the AWS CLI is installed and configured, and that the stack name is 'Tomcat10'.

• app: This is the test application that is compiled and deployed on Tomcat as part of the CloudFormation stack creation. Its a simple 'hello world'.

Usage

1. Make sure you have the AWS CLI installed and configured with a profile named 'default'.

2. To deploy the stack, run the deployStack.sh script:

   bash deployStack.sh

3. To delete the stack, run the deleteStack.sh script:

   bash deleteStack.sh

Please note that the stack name 'Tomcat10' is hardcoded in the scripts. If you want to use a different stack name, you will need to modify the scripts accordingly.

Requirements

• AWS CLI
• AWS account with permissions to create EC2 instances and security groups
• Bash shell to run the scripts
