Terraform Openstack

This will create:

dmznet and dmzsubnet

borderrouter that connects dmznet to bright-external-flat-externalnet

a floating ip address, and an instance coming off of dmznet

clusternet off of dmznet instance

clustersubnet eill connect instance to ood through ohpc and download software

Make a new directory for Terraform:

$mkdir terraform-first-instance

Install Terraform:

$brew install terraform

Unzip the file and make a path to your new directory:

$export TERRAFORM_DIR="$(pwd)/terraform-first-instance"

$cp $HOME/Downloads/terraform_0.6.16_linux_amd64/terraform $TERRAFORM_DIR

Create a new application credintial in Openstack:

In Openstack, go to Identity - Application Credentials

Click "Create Application Credential"

Name the credential and add a description(Leave the rest blank. It is important not to add an expiration date.)

Open the credential rc file you have created, and change all OS_ to TF_. This will allow terraform to read and use these values.

Save the credential in your terraform-first-instance directory.

Download RC File from Openstack(V3) and save it in your terraform-first-instance directory.

Clone this repo into your terraform-first-instance directory:

$git clone --recursive https://gitlab.rc.uab.edu/rrand11/terraform-openstack.git

Source the openrc file and enter your password for openstack (you will only need to do this the very first time):

$source OPENRCFILENAME

Source the credential rc file and initialize terraform:

$source CREDENTIALRCFILENAME

$cd terraform-openstack

$terraform init

Write Terraform Plan to your terraform-first-instance directory and run that plan:

$terraform plan -out $HOME/terraform-first-instance/terraform-plan.tf

#terraform plan -out writes the plan to a file and then terraform apply runs that plan

$terraform apply "$HOME/terraform-first-instance/terraform-plan.tf"

Destroy Terraform Instance:

$terraform destroy
