## Getting Started
### Prerequisites
### Setup AWS Credentials:
As a prerequisite first, we have to set AWS credentials for both our development and production AWS accounts
IAM configuration to `~/.aws/credentials`(For Mac) consisting of proper IAM permissions. For temporary credentials also
add the session key.
```
[dev]
aws_access_key_id =
aws_secret_access_key =
[prod]
aws_access_key_id =
aws_secret_access_key =
aws_session_token=
```
### Remote Backend & Variables
1.Backend Infra setup for example for s3+dynamodb:
`backend.tf`
```tf
terraform {
backend "s3" {
bucket = ""
encrypt = true
key = "path/terraform.tfstate"
region = ""
dynamodb_table = ""
}
}
```
2. Key value .tfvars configuration file example with sensetive data:
`dev.tfvars`
```tfvars
# Generic variables
project = "terrasample"
aws_region = ""
profile = "terrasample-dev"
environment = "dev"
```
### Initialize the Project
```bash
terraform init
```
### Basic Terraform Commands
## Basic Terraform Commands
### Changing Environment in Terraform:
Select development environment:
```bash
terraform workspace select dev
```
Select production environment:
```bash
terraform workspace select prod
```
#### Plan:
```bash
# For Development Environment
terraform workspace select dev && terraform plan -var-file="dev.tfvars"
# For Production Environment
terraform workspace select dev && terraform plan -var-file="prod.tfvars"
```
#### Apply:
```bash
# For Development Environment
terraform workspace select dev && terraform apply -var-file="dev.tfvars"
# For Production Environment
terraform workspace select dev && terraform apply -var-file="prod.tfvars"
