Prerequisites

List the software and tools that need to be installed before setting up the project.

• aws-cli install
• terraform install
• kubectl install
• shell scripts

Installation

Step-by-step instructions to install the project.

1. aws-cli install

   brew install aws-cli

2. terraform install

   brew tap hashicorp/tap
   brew install hashicorp/tap/terraform

3. kubectl install(1.29)

   curl -O https://s3.us-west-2.amazonaws.com/amazon-eks/1.29.0/2024-01-04/bin/darwin/amd64/kubectl
   curl -O https://s3.us-west-2.amazonaws.com/amazon-eks/1.29.0/2024-01-04/bin/darwin/amd64/kubectl.sha256
   openssl sha1 -sha256 kubectl
   chmod +x ./kubectl
   mkdir -p $HOME/bin && cp ./kubectl $HOME/bin/kubectl && export PATH=$HOME/bin:$PATH
   echo 'export PATH=$HOME/bin:$PATH' >> ~/.bash_profile

Configuration

Pre-setup for Terraform on AWS: S3 Bucket and DynamoDB Table with aws-cli

1. Create a S3

   aws s3api create-bucket --bucket terraform-state-js-test --region ap-northeast-2 --create-bucket-configuration LocationConstraint=ap-northeast-2
   aws s3api put-bucket-versioning --bucket terraform-state-js-test --versioning-configuration Status=Enabled
   

2. Create a DynamoDB

   aws dynamodb create-table \
   --table-name terraform-locks \
   --attribute-definitions AttributeName=LockID,AttributeType=S \
   --key-schema AttributeName=LockID,KeyType=HASH \
   --provisioned-throughput ReadCapacityUnits=1,WriteCapacityUnits=1
   

Usage

1. Plan the changes:

   terraform init
   terraform plan

   The terraform plan command creates an execution plan, which lets you preview the changes that Terraform plans to make to your infrastructure.

2. Apply the changes:

   terraform apply

   The terraform apply command executes the actions proposed in a Terraform plan to create, update, or destroy resources.

3. Destroy the infrastructure:

   terraform destroy
