Terraforming the Cloud

This is an example repo to demonstrate terraform with GCP and Azure as part of a talk.

The examples in this repo where developed using Hashicorp's Terraform Get Started guides for Azure and GCP.

What you will need

A terraform installation: https://learn.hashicorp.com/tutorials/terraform/install-cli
An account with your chosen cloud provider
- If you choose Google Cloud, you will also need to create a service account and generate a key for it
The command line interface installation for your chosen cloud provider, either:
- Azure: https://docs.microsoft.com/en-us/cli/azure/install-azure-cli
- Google Cloud: https://cloud.google.com/sdk/docs/install

Clone the repo

git clone https://github.com/sgibson91/terraform-example.git
cd terraform-example

Change into the terraform subdirectory of your chosen cloud provider
```
cd terraform/{{ azure | gcp }}
```

Authenticate with your chosen cloud provider

# For Azure
az login
# For Google Cloud
gcloud auth login

Create a copy of inputs.example.tfvars and replace the placeholder values with your desired inputs. You may even choose to change some other values that are listed in variables.tf.
```
cp inputs.example.tfvars inputs.tfvars
```
Initialise terraform
```
terraform init
```

Plan your infrastructure changes

terraform plan -var-file=inputs.tfvars -out=plan

💡 Steps 6 and 7 can be repeated as many times as you wish as you make changes to your infrastructure

Once you are finished, destroy your infrastructure

terraform plan -var-file=inputs.tfvars -out-plan -destroy
terraform apply plan
