This project contains Terraform scripts to provision Google GCP infrastructure resources required to deploy SAS Viya 4 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 CAS in SMP or MPP mode
• Shared Storage options for SAS Viya - Google Filestore (ha) or NFS Server (standard)
• Google Cloud SQL for PostgreSQL instance, optional

Once the cloud resources are provisioned, see the viya4-deployment repo to deploy SAS Viya 4 products. If you need more information on the SAS Viya 4 products refer to the official SAS® Viya® 4 Operations documentation for more details.

Operational knowledge of

• Terraform
• Docker
• Google Cloud Platform
• Kubernetes

• Access to a Google Cloud "Project" with these API Services enabled.

• A Google Cloud Service Account.

    • Docker

Run these commands in a Terminal session:

# clone this repo
git clone https://github.com/sassoftware/viya4-iac-gcp

# move to directory
cd viya4-iac-gcp

See Terraform GCP Authentication for details.

Create a file named terraform.tfvars to customize any input variable value documented in the 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 file.

NOTE: You will need to update the cidr_blocks in the variables.tf file to allow traffic from your current network. Without these rules, access to the cluster will only be allowed via the GCP Console.

When using a variable definition file other than terraform.tfvars, see Advanced Terraform Usage for additional command options.

Create and manage the GCP cloud resources by either

• using Terraform directly on your workstation, or
• using a Docker container.

See troubleshooting page.
