Terraform infra for Jenkins Server

Terraform commands

Initializes the working directory containing Terraform configuration files:

$ terraform init

Rewrite Terraform configuration files to a canonical format and style:

$ terraform fmt .

Validate the configuration files in a directory:

$ terraform validate .

Building the cloud infrastructure

Creates an execution plan, which lets you preview the changes that Terraform plans to make to your infrastructure:

$ terraform plan

Apply a configuration to build infra:

$ terraform apply

Destroying the cloud infrastructure

Destroy infrastructure:

$ terraform destroy  

Infrastructure managed outside of Terraform

1. Elastic IP: Due to frequent terraform apply and destroy operations, elastic IP is managed independently of Terraform, so as to attach the same elastic IP everytime on doing a 'terraform apply', and dissociating it (not detroy) on doing a 'terraform destroy'.

2. DNS Hosted Zone: Hosted zone is a permanent resource, need not be destroyed and recreated everytime with tf apply and destroy operations.
