Provision AWS instance.

Requirements

• The steps below were successfully tested using:
  • Terraform (0.14.4)

Install Terraform

• Go to url

AWS Credentials.

• Export these variables

export AWS_ACCESS_KEY_ID="XXX"
export AWS_SECRET_ACCESS_KEY="YYY"
export AWS_DEFAULT_REGION="us-west-2"

Overriding Variables

• The quickest way to override the variables (Emails, Services, Budget Limits) with experimental changes is to copy vars.tf to the override terraform file.

• For more on overriding variables Go to url

cp vars.tf _override.tf

EMAILS

• Add email addresses as needed.

variable "emails" {
  description = "List of emails"
  type = list(string)
  default = ["xxx@gmail.com"]
}

Services and Budget Limts :

Example using EC2 and S3 services. You can add other services specified in service.tf.

variable "account_budget_limit" {
  type = string
  default = "20.0"
}

variable "services" {
  default = {
    EC2 = {
      budget_limit = "10.0"
    },
    S3 = {
      budget_limit = "5.0"
    }
  }
}

Deploy:

Note: Terraform creates some folders and files to maintain the state. Use ls -a aws

# This will install the aws terraform provider. 
terraform init

# Validate the config
terraform validate

# View what is going to be created. The plan.
terraform plan

# This will create the budgets
terraform apply

#To view:
terraform show 

#To destroy:
terraform destroy
