Hello Everyone

Welcome to CloudAffaire and this is Debjeet.

In the last blog post, we have created a CloudFormation stack using a sample template provided by AWS.

https://cloudaffaire.com/create-cloudformation-stack/

In this blog post, we are going to create our 1st CloudFormation template and using this template we will create a CloudFormation stack in AWS console. We have tried to include most of the template elements in this demo.

Create CloudFormation Template:

Step 1: Login to AWS console and navigate to ‘CloudFormation’.

Create CloudFormation Template

Note: For shortening of the code, only has AMI mapping for APAC regions. Make sure you are in any one of the APAC regions.

Step 2: Click ‘Create Stack’.

Step 3: Open your favorite editor and create a file with .yaml extension using below YAML code.

Note: Make sure code indentation id correct or you can download the template_elements_demo.yaml file from below GitHub repo.

Step 4: Select ‘Template is ready’ and then ‘Upload a template file’, click ‘Choose file’ to upload the file and click ‘Next’.

Step 5: Provide name, parameters for your stack and click ‘Next’.

Step 6: Leave ‘Configure stack options’ as it is and click ‘Next’.

Step 7: Review your stack configuration and click ‘Create stack’.

Note: It will take some time to complete the stack creation. You can monitor the progress in ‘Events’ section.

Our stack successfully created using the template created in step 3.

Correlate the code with below tabs output for your understanding.

Events: Stack creation details with the timeline (used for troubleshooting if stack creation failed)

Resource: AWS resources created under this stack (in our case one EC2 instance, if db then elastic IP)

Outputs: Values that are returned (In our instance id, type and if db then elastic IP address)

Parameters: Values passed to your template at runtime (cache or web or db)

Template: The actual code for this stack (defined in step 3)

Step 8: Cleanup.

Note: This will also delete the underlying resources for this stack.

Hope you have enjoyed this article. In the next blog post, we will create a template using CloudFormation Designer.
