+# GCP-GKE
+
+Cluster.dev uses [stack templates](https://docs.cluster.dev/stack-templates-overview/) to generate users' projects in a desired cloud. GCP-GKE is a stack template that creates and provisions Kubernetes clusters in GCP cloud by means of Google Kubernetes Engine (GKE).
+
+In this repository you will find all information and samples necessary to start an GKE cluster on GPC with Cluster.dev. 
+
+The resources to be created:
+
+* VPC
+* GKE Kubernetes cluster with addons:
+  * cert-manager
+  * ingress-nginx
+  * external-secrets (with GCP Secret Manager backend)
+  * external-dns
+  * argocd
+
+## Prerequisites
+
+1. Terraform version >= 1.4
+2. GCP account and project.
+3. GCloud CLI installed and configured with your GCP account.
+4. kubectl installed.
+5. [Cluster.dev client installed](https://docs.cluster.dev/get-started-install/).
+6. Parent Domain
+
+## Before you begin
+
+1.  [Create or select a Google Cloud project.](https://console.cloud.google.com/project)
+    ```
+    gcloud projects create cdev-demo
+    gcloud config set project cdev-demo
+    ```
+
+2.  [Enable billing for your project.](https://support.google.com/cloud/answer/6293499#enable-billing)
+
+3.  [Enable the Google Kubernetes Engine API.](https://console.cloud.google.com/flows/enableapi?apiid=container,cloudresourcemanager.googleapis.com)
+
+4. Enable Secret Manager
+   ```
+   gcloud services enable secretmanager.googleapis.com
+   ```
+
+
+## Quick Start
+1. Clone example project:
+    ```
+    git clone https://github.com/shalb/cdev-gcp-gke.git
+    cd examples/
+    ```
+2. Update project.yaml
+    ```
+    name: demo-project
+    kind: Project
+    backend: default
+    variables:
+      organization: my-organization
+      project: cdev-demo
+      region: us-west1
+      state_bucket_name: gke-demo-state
+      state_bucket_prefix: demo
+    ```
+3. Create GCO bucket for terraform backend
+    ```
+    gcloud projects create cdev-demo
+    gcloud config set project cdev-demo
+    gsutil mb gs://gke-demo-state
+    ```
+4. Edit variables in the example's files, if necessary.
+5. Run `cdev plan`
+6. Run `cdev apply`
+7. Setup DNS delegation for subdomain by creating
+   NS records for subdomain in parent domain
+   Run `cdev output`
+   ```
+   cdev output
+   12:58:52 [INFO] Printer: 'cluster.outputs', Output:
+   domain = demo.gcp.cluster.dev.
+   name_server = [
+     "ns-cloud-d1.googledomains.com.",
+     "ns-cloud-d2.googledomains.com.",
+     "ns-cloud-d3.googledomains.com.",
+     "ns-cloud-d4.googledomains.com."
+   ]
+   region = us-west1
+   ```
+   add records from name_server list
+
+8. Authorize cdev/terraform to interact with GCP via SDK
+    ```
+    gcloud auth application-default login
+    ```
+9. Connect to GKE cluster
+    ```
+    gcloud components install gke-gcloud-auth-plugin
+    gcloud container clusters get-credentials demo-cluster --zone us-west1-a --project cdev-demo
+    ```
+10. Retrieve ArgoCD admin password
+   install argocd cli 
+    ```
+    kubectl -n argocd get secret argocd-initial-admin-secret  -o jsonpath="{.data.password}" | base64 -d; echo
+   ```
