• Overview
  

Variables

• Terraform variables allows users to pass the values during execution
• Variable block supports the arguments as listed here
• syntax

variable <name> {
    type = 
}

• Generally as per google’s style guide we create all the variables in variables.tf or inputs.tf
• To use the variable the syntax is var.<name>
• Refer Here for the variables added to aws vpc and 4 subnets
• We can create a file <name>.tfvars where we can apply all the values and pass this file during terraform apply
• Generally we will have <environment>.tfvars
• Refer Here for changes done
• Few variables to pass

terraform apply -var var1=value1 -var var2=value2 

• many variables to pass, create a .tfvars file such as dev.tfvars

terraform apply -var-file="dev.tfvars"

• Refer Here for variables with object types
