CloudFormation Examples

This repository contains CloudFormation example templates, each building on the previous stack:

• Create Basic Amazon EC2 Instance
• Enable SSH and HTTP/HTTPS Traffic
• Assign an IP Address and Output the Website URL
• Make the Template Dynamic
• Add RDS Postgresql Database
• Enable Inbound Traffic on Port 5432
• Add CodeDeploy agent, tags, and CodeDeployTrustRole
• Create CodePipeline
• Delete Your Stacks & Snapshots

This repository accompanies the following blog posts:

• Provisioning an EC2 Instance with CloudFormation (part 1)
• Provisioning an RDS Database with CloudFormation (part 2)
• Using CloudFormation to Automate Build, Test, and Deploy with CodePipeline (part 3)

1. Create Basic Amazon EC2 Instance

To create the stack using this template, run the create-stack command-line:

$ aws cloudformation create-stack --stack-name ec2-rds-example --template-body file://01_ec2.yaml

2. Enable SSH and HTTP/HTTPS Traffic

You can update your stack using the update-stack command:

$ aws cloudformation update-stack --stack-name ec2-rds-example --template-body file://02_ec2.yaml

3. Assign an IP Address and Output the Website URL

You can update your stack using the update-stack command:

$ aws cloudformation update-stack --stack-name ec2-rds-example --template-body file://03_ec2.yaml

4. Make the Template Dynamic

You can update the stack with this command, passing in the parameter values:

$ aws cloudformation update-stack --stack-name ec2-rds-example --template-body file://04_ec2.yaml \
--parameters ParameterKey=AvailabilityZone,ParameterValue=us-east-1a \
ParameterKey=EnvironmentType,ParameterValue=dev \
ParameterKey=KeyPairName,ParameterValue=jenna

5. Add RDS Postgresql Database

You can update the stack with this command, passing in the parameter values:

$ aws cloudformation update-stack --stack-name ec2-rds-example --template-body file://05_rds.yaml \
--parameters ParameterKey=AvailabilityZone,ParameterValue=us-east-1a \
ParameterKey=EnvironmentType,ParameterValue=dev \
ParameterKey=KeyPairName,ParameterValue=jenna \
ParameterKey=DBPassword,ParameterValue=Abcd1234

6. Enable Inbound Traffic on Port 5432

You can update the stack with this command, passing in the parameter values:

$ aws cloudformation update-stack --stack-name ec2-rds-example --template-body file://06_rds.yaml \
--parameters ParameterKey=AvailabilityZone,ParameterValue=us-east-1a \
ParameterKey=EnvironmentType,ParameterValue=dev \
ParameterKey=KeyPairName,ParameterValue=jenna \
ParameterKey=DBPassword,ParameterValue=Abcd1234

7. Delete Your Stacks & Snapshots

Don’t forget to delete your stack so you don’t accrue charges. You can do that with the delete-stack command:

$ aws cloudformation delete-stack --stack-name ec2-rds-example

If you left the DeletionPolicy and UpdateReplacePolicy properties set to snapshot and you no longer need those snapshots, then you can also delete those snapshots using the AWS Console so you don't accrue charges for those either.

Navigate to the RDS Management Console. From there, go to the Snapshots menu option. Select the snapshots created from your stack (hint: they will have a snapshot name that starts with your stack name) and select Delete snapshot from the Actions menu.
