Using AWS CloudFormation in Go: A Complete Guide

AWS CloudFormation is an exciting AWS cloud computing service that allows you to build and manage infrastructure in a fraction of the time without actually dealing with various underlying services. In this article, we will learn how to use AWS CloudFormation in Go language to manage and deploy AWS infrastructure. This article will introduce the following content:

What is AWS CloudFormation?

AWS CloudFormation is a comprehensive cloud-based service that allows administrators and developers to easily create and deploy infrastructure resources and applications. AWS CloudFormation gives users the ability to maintain consistency and repeatability in AWS and manage services in a fully automated manner. Call it "infrastructure as code".

AWS CloudFormation provides a DSL (Domain Specific Language) to help you define and deploy infrastructure. The DSL is in JSON or YAML format, very similar to the Go language.

Configuring AWS CloudFormation

To start using AWS CloudFormation, you need to install and configure the AWS CLI (Command Line Interface). The AWS CLI is a command line tool that allows you to easily interact with AWS resources.

1. First you need to install the AWS CLI command line tool, which can be downloaded from the official website or installed through the package manager.
2. Associate security credentials with the AWS CLI: It is best to use an IAM user to provide security credentials, so that you can control the scope of AWS services that the user can operate.
3. Create a stack using the AWS CLI: Define the infrastructure in JSON or YAML format and use the AWS CLI to create one or more stacks.

Manage Infrastructure

In your AWS cloud, a stack is a set of AWS resources that depend on each other. AWS CloudFormation manages the stack by running templates on the stack and automatically creating, updating, and deleting AWS resources.

1. Using AWS CloudFormation templates: In your AWS cloud, AWS CloudFormation templates act as declarative blueprints for the AWS resources in the stack. Define templates via JSON or YAML format and run them on the stack to automatically create, update, and delete AWS resources for your infrastructure.
2. Create and update stacks and resources: You can use the AWS CLI or AWS CloudFormation console to directly create and update one or more stacks and resources. You can also use the AWS SDK (such as Go SDK) to write code to manage the stack and interact with it. to interact with the AWS cloud.
3. Other options for creating infrastructure:

Infrastructure that changes frequently can adopt code-based development, such as: GitHub, Bitbucket, GitLab, etc. How to define in the code Infrastructure works with AWS CloudFormation templates. In addition to the most convenient GitHub, the AWS CLI can also easily integrate your application's GitHub repository into the AWS build pipeline.

4. Apply AWS CloudFormation templates to design security for applications: For any security manager, security is their top priority. AWS CloudFormation templates help include security in your application because the template contains certain resources that set security settings for the application. For example, you can define AWS Identity and Access Management (IAM) roles, security groups, network ACLs, and other resource contents.

AWS CloudFormation in Go

You can use the AWS Go SDK (Pipelines and AWS CloudFormation Go SDK) to operate stacks in the AWS cloud. The Go SDK is a powerful tool that provides support for interactions between major services, APIs, and AWS resources in AWS. Go language is very suitable for handling concurrent operations.

Installation pipeline:

go get -u github.com/aws/aws-sdk-go/...

Install AWS CloudFormation SDK:

go get -u github.com/aws/aws-sdk-go/service/cloudformation

import "github.com/aws/aws-sdk-go/aws/session"
import "github .com/aws/aws-sdk-go/aws"

// Credentials and categories and changing the default zone
mysession := session.Must(session.NewSessionWithOptions(session.Options{
Config :aws.Config{

Region:aws.String("us-west-2”)},
CredentialsProvider：credentials.NewSharedCredentials("", "default")

}))
cf := cloudformation.New(mysession)

Work better with AWS CloudFormation

AWS CloudFormation templates are Define infrastructure best practices. Include all resources and deployment operations that must be completed in the template to make the operation of the infrastructure simple and clear.

It is recommended to store templates in a source code version control repository and manage them along with the software development and deployment process. This way, you can easily deploy the same infrastructure in every environment without having to do it manually every time.
