This repository is needed for sample app deployments in GCP, that can be found here: gke-sample-app-deployment.

All of the code is based on official HashiCorp tutorial. You can use it to deploy: vpc & subnet, GKE cluster, GCR.

To do so:

1. Clone this repository.
2. Install Terraform (version: 0.15+).
3. Install Google Cloud SDK
4. Log in to your GCP project from command line (gcloud init)
5. [Optional] Create terraform.auto.tfvars - add variable values for region, zone, project_id (you will be prompted to provide them if you won't create this file).
6. Change backend configuration in terraform_config.tf - use your own Terraform Organisation and Workspace - if you don't want to use Terraform Cloud - change backend type to local. (if you do so, you will also have to amend code within gke-sample-app-deployment repository to get information about GKE clusters from different location than shared remote backend)

If you will use Terraform Cloud, open your terminal and log in:

terraform login

While creating namespace: make sure to set execution mode to local and select CLI-driven runs.

7. Inside gke-infra/ folder run:

terraform init
terrafom plan
terrafom apply

8. Approve terraform apply and wait for around 10 mins for cluster to deploy.

9. Remember to remove your resources when you no longer need them with:

terraform destroy

This infrastructure will generate costs, check GCP documentation to learn more.

This infrastructure is only a demo, it does not contain production-ready environment. Currently GKE cluster is deployed in single zone.
