Instructions for setting up infrastructure using Terraform:

• docs
• Install Terraform:

  • sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
  • sudo apt-get update && sudo apt-get install terraform
• Verify the installation
  • terraform -help
• Initialize the directory
  • terraform init && terraform plan
• Format and validate the configuration
  • terraform fmt
  • terraform validate
• Create infrastructure
  • terraform apply
• Inspect state
  • terraform show
• Destroy Infrastructure
  • terraform destroy

Demo commands:

• build vpc:
  • go to /VPCs/0x/
  • export AWS_PROFILE=prod //for dev: export AWS_PROFILE=dev
  • terraform init && terraform plan
  • terraform apply
  • terraform destroy
• build all resources:
  • cd modules/services
  • export AWS_PROFILE=prod
  • alias t=terraform
  • t init && t plan -var 'env=prod'
  • t apply -var 'env=prod'//for dev: t apply -var 'env=dev'

SSL:

1. prepare ssl: get private key and CSR

• namecheap
• commands:

sudo openssl genrsa -out private.key 2048 # generate the private key
sudo openssl req -new -key private.key -out csr.pem # generate CSR based on the Private Key

2. activate on namecheap
3. set up CNAME in DNS, in my case: it's in aws route53
4. install ssl: import in aws certificate manager

• namecheap

5. Set up in load balancer: two options

• Load Balancers menu >> Listeners >> View/edit certificates
• Command:

aws elb set-load-balancer-listener-ssl-certificate --load-balancer-name my-loadbalancer --load-balancer-port 443 --ssl-certificate-id arn:aws:iam::123456789012:server-certificate/certificate_object_name

Parameter my-loadbalancer is the name of your load balancer.
