Kubernetes - TerraForm

 

Installation: https://www.decodingdevops.com/how-to-install-terraform-on-windows-10-or-8-or-7/

Create a .tf file

provider "aws" {
   region = "us-east-1"
}

cd to the folder where .tf file resides, run "terraform init" and terraform will downlaod the aws provider to local diretory

terrform aws provider cli : https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html

 

 Create IAM account at AWS cloud, and simply assign it the admin role to have all acess

 

 

 

 Use following script to create S3 

provider "aws" {
   region = "us-east-1"
   access_key = "AKIA***"
   secret_key = "hMHx***"
   #shared_credentials_file="E:/K8S/FromAppToK8S/Script/KubeK8S/Terraform"
   #profile = "mattcoder1"
}

resource "aws_s3_bucket" "s3-matt-bucket"{
  bucket = "s3-matt-bucket"
}

 Using terraform console for query

 

 AWS Region - Availability Zone - VPC (Virtual private cloud)

1 Region -  1 VPC - Mutltiple AZ

 

 Use terraform to create EC2 instance

Firstly collect all required info
