Laboratorio # 3: creación de recursos del Stack

How to deploy resources on AWS with a Stack?

Leveraging the capabilities of Amazon Web Services to deploy applications and resources is essential for any developer. In this lab, focusing on deploying Votan Help, you will learn how to use a Stack to create and configure resources such as API Gateway, Lambda and DynamoDB efficiently. The structure and coordination of these elements is crucial for a successful project, and here we show you how to achieve it.

How to clone the code repository?

To begin with, it is important to have the correct source code. Go to your code repository and clone it by following these steps:

1. Copy the repository URL.
2. Open your terminal and use the command git clone followed by the copied URL.
3. Verify that the clone was successful by checking the folder structure of the repository on your local system.

How to prepare the AWS S3 environment for the project?

Amazon S3 is an essential object storage service where the code and files needed for Lambda are stored. Here's how to set it up:

1. Access the Amazon S3 console and create a bucket if you don't already have one. You just need to specify the name.
2. Once the bucket is created, upload the compressed code of the Lambda function in .zip or .pkg format. This file will be key to deploy the Lambda function.

How to upload and configure the Stack in AWS CloudFormation?

CloudFormation is used to deploy and manage multiple resources on AWS with a single template. Here's how to do it:

1. Copy the full URL of the master template file from the code repository in S3.
2. Access the AWS CloudFormation console and select "Create Stack".
3. Provide the copied URL as the source of your template.
4. Fill in the required fields, such as the Stack name (e.g. VotaNextMaster) and project-specific details such as DynamoDB table name, primary key, Lambda function name and S3 bucket where the code is stored.

What aspects are vital when creating a Stack?

During the Stack creation process, there are several important aspects to consider to avoid errors. These include:

• Make sure you select the necessary IaaM permissions, especially when creating roles and policies.
• Review each step before proceeding to ensure that the settings and configurations are correct.
• Monitor the deployment process, verifying that each resource is successfully created through the CloudFormation status.

How to verify that the resources have been created correctly?

After Stack creation, it is essential to ensure that each resource is working correctly:

• Lambda: Confirm that the Lambda function is deployed and configured to run with the appropriate runtime (e.g., Python 3.7). Verify policies and permissions.

• DynamoDB: Check that the DynamoDB table exists and has the correct keys configured. It is important to have the main things, such as citizenship card, ready for queries.

• API Gateway: Verify the creation of the endpoints in API Gateway, making sure they are correctly integrated with the Lambda function.

This detailed approach gives you the clarity and security you need to deploy projects on AWS, enabling you to take your applications to the next level with confidence.
