Terraform Installation

1. Download Terraform from terroform.io

   For Mac,

   wget https://releases.hashicorp.com/terraform/0.11.11/terraform_0.11.11_darwin_amd64.zip -O /tmp/terraform.zip
   

   For Linux,

   wget https://releases.hashicorp.com/terraform/0.11.11/terraform_0.11.11_linux_amd64.zip -O /tmp/terraform.zip
   

2. Extract to a directory

   mkdir -p mkdir -p ${HOME}/terraform
   unzip /tmp/terraform.zip -d ${HOME}/terraform/
   

3. Set Classpath

   echo 'export PATH=${HOME}/terraform:${PATH}' >> ~/.bashrc
   source ~/.bashrc
   

Configure AWS

Make sure to configure AWS credentials so that terraform can create/manage AWS resources.

Create/Open ~/.aws/credentials file and make sure it has access key and secret access key

[demo]
region = us-west-2
output = json
aws_access_key_id = <YOUR AWS ACCESS KEY ID>
aws_secret_access_key = <YOUR AWS SECRET ACCESS KEY ID>

Run Terraform

Running these(Terraform) examples may incur charge in AWS account.

1. Navigate to code directory (let's say demo2/)
2. Put one tfvars file under env directory for each environment. (Refer example.tfvars file)
3. Run terraform init to initialize terraform
4. Run terraform plan -var-file=env/demo.tfvars to see the plan (Let's say demo.tfvars is for demo environment)
5. If happy with the plan, run terraform apply -var-file=env/demo.tfvars
6. If want to cleanup(or destroy all resources created by this example terraform code), run terraform destroy -var-file=env/demo.tfvars
