# SAS Viya 4 Infrastructure as Code (IaC) for Google Cloud
## Overview
This project contains Terraform scripts to provision Google Cloud infrastructure resources required to deploy SAS Viya 4 platform products. Here is a list of resources this project can create -
>- VPC Network and Network Firewalls
>- Managed Google Kubernetes Engine (GKE) cluster
>- System and User GKE Node pools with required Labels and Taints
>- Infrastructure to deploy SAS Viya platform CAS in SMP or MPP mode
>- Shared Storage options for SAS Viya platform - Google Filestore (ha), Google NetApp Volumes (ha) or NFS Server (standard)
>- Google Cloud SQL for PostgreSQL instance, optional

Once the cloud resources are provisioned, see the [viya4-deployment](https://github.com/sassoftware/viya4-deployment) repository to deploy SAS Viya 4 platform products. If you need more information on the SAS Viya 4 platform products refer to the official [SAS® Viya® platform Operations](https://documentation.sas.com/?cdcId=itopscdc&cdcVersion=default&docsetId=itopswlcm&docsetTarget=home.htm) documentation for more details.
## Prerequisites
Operational knowledge of
- [Terraform](https://www.terraform.io/intro/index.html)
- [Docker](https://www.docker.com/)
- [Google Cloud](https://cloud.google.com/)
- [Kubernetes](https://kubernetes.io/docs/concepts/)
### Required
- Access to a [**Google Cloud "Project"**](https://cloud.google.com/resource-manager/docs/creating-managing-projects) with [these API Services](docs/user/APIServices.md) enabled.
- A [Google Cloud Service Account](./docs/user/TerraformGCPAuthentication.md).
- Terraform or Docker
- #### Terraform
- [Terraform](https://www.terraform.io/downloads.html) - v1.10.5
- [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl) - v1.30.10
- [jq](https://stedolan.github.io/jq/) - v1.7
- [gcloud CLI](https://cloud.google.com/sdk/gcloud) - (optional - useful as an alternative to the Google Cloud Platform Portal) - v513.0.0
- [gke-gcloud-auth-plugin](https://cloud.google.com/kubernetes-engine/docs/how-to/cluster-access-for-kubectl#install_plugin) - (optional - only for provider based Kubernetes configuration files) - >= v1.26
- #### Docker
- [Docker](https://docs.docker.com/get-docker/)
## Getting Started
### Clone this project
Run these commands in a Terminal session:
```bash
# clone this repository
git clone https://github.com/sassoftware/viya4-iac-gcp
# move to directory
cd viya4-iac-gcp
```
### Authenticating Terraform to access Google Cloud
See [Terraform Google Cloud Authentication](./docs/user/TerraformGCPAuthentication.md) for details.
### Customize Input Values
Create a file named `terraform.tfvars` to customize any input variable value documented in the [CONFIG-VARS.md](docs/CONFIG-VARS.md) file. For starters, you can copy one of the provided example variable definition files in `./examples` folder. For more details on the variables declared refer to the [CONFIG-VARS.md](docs/CONFIG-VARS.md) file.
**NOTE:** You will need to update the `cidr_blocks` in the [variables.tf](variables.tf) file to allow traffic from your current network. Without these rules, access to the cluster will only be allowed via the Google Cloud Console.
When using a variable definition file other than `terraform.tfvars`, see [Advanced Terraform Usage](docs/user/AdvancedTerraformUsage.md) for additional command options.
## Creating and Managing the Cloud Resources
Create and manage the Google Cloud resources by either
- using [Terraform](docs/user/TerraformUsage.md) directly on your workstation, or
- using a [Docker container](docs/user/DockerUsage.md).
## Troubleshooting
See [troubleshooting](./docs/Troubleshooting.md) page.
