Terraform basic infrastructure setup with AWS for practice.

Working towards this diagram setup:

• Use backend_setup/ to create two separate AWS S3 buckets for TF State storage (development and production)

• The TF State for the backend is managed locally (init and apply from within backend_setup/)

• Update the bucket name in the appropriate backend.hcl file: environments/<env>/backend.hcl

• terraform init/apply from environments/dev or environments/prd

• Provide the backend config path: terraform init -backend-config=backend.hcl

• Before init/apply, create an SSH keypair: ssh-keygen -b 2048 -t rsa -f infra-key from within environments/<env>

• Save the private infra-key file to SSH onto the Bastion EC2, the infra-key.pub can be deleted after init/apply (it gets installed onto the EC2 instance)

• SSH to bastion host: ssh -i infra-key ec2-user@<bastion-host Public IP>

• Or SSH to bastion host and then to the private instance:

ssh-add infra-key
ssh -A ec2-user@<bastion-host Public IP>
ssh ec2-user@<private-instance Private IP>
