The GKE Proof of Concept (PoC) Toolkit is a demo generator for [Google Kubernetes Engine](https://cloud.google.com/kubernetes-engine).

![demo-gif](https://raw.githubusercontent.com/GoogleCloudPlatform/gke-poc-toolkit/main/assets/demo.gif)
  
## Quickstart

1. **[Create a Google Cloud Project](https://cloud.google.com/resource-manager/docs/creating-managing-projects)** and connect it to an existing Billing account.
2. **Open a bash-compatible shell** (eg. [Google Cloud Shell](https://cloud.google.com/shell)) and ensure you have the following tools installed:

* [Google Cloud SDK version >= 325.0.0](https://cloud.google.com/sdk/docs/downloads-versioned-archives)
* * [Terraform >= 0.13](https://www.terraform.io/downloads.html)
* [kubectl](https://kubernetes.io/docs/tasks/tools/) ( >= v1.20)

3. **Set your Project ID environment variable and operating system.**

```bash
export PROJECT_ID=<your-project-id>
export OS="darwin" # choice of darwin or amd64 
```

4. **Set up local authentication to your project.**

```
gcloud config set project $PROJECT_ID
gcloud auth login
gcloud auth application-default login
```

5. **Download the GKE PoC Toolkit binary.**

```shell
mkdir gke-poc-toolkit && cd "$_"
VERSION=$(curl -s https://api.github.com/repos/GoogleCloudPlatform/gke-poc-toolkit/releases/latest | grep browser_download_url | cut -d "/" -f 8 | tail -1)
curl -sLSf -o ./gkekitctl https://github.com/GoogleCloudPlatform/gke-poc-toolkit/releases/download/${VERSION}/gkekitctl-${OS} && chmod +x ./gkekitctl
```

6. **Initialize the cli:**
```bash 
./gkekitctl init
```

7. **Run `gkekitctl apply` to run the Toolkit.** By default, this command sets up a single-cluster GKE environment. ([Configuration here](cli/pkg/cli_init/samples/default-config.yaml)). Enter your project ID when prompted.

```shell
./gkekitctl apply
```
```shell
# expected output 
INFO[0000] ☸️ ----- GKE POC TOOLKIT ----- 🛠
INFO[0000] Enter your Google Cloud Project ID:
```

This command takes about **10 minutes** to run; when it completes, you will have a full GKE demo environment ready to explore and deploy applications to.

```bash
# Expected output on successful run

```

## Update

If you want to update your environment change the config file and re-run the apply command. This is a great way to add or remove clusters.
```bash
## Local tf state 
./gkekitctl apply --config <"config file name">

## If you are using remote TF state 
./gkekitctl apply --config <"config file name"> --gkestate <"bucket name used for state file"> --vpcstate <"if using sharevpc, bucket name for shared vpc state file">
```

## Clean up

```bash
./gkekitctl delete
```
