Quickstart

  1. Create a Google Cloud Project and connect it to an existing Billing account.
  2. Open a bash-compatible shell (eg. Google Cloud Shell) and ensure you have the following tools installed:
  1. Set your Project ID environment variable and operating system.
export PROJECT_ID=<your-project-id>
export OS="darwin" # choice of darwin or amd64
  1. Set up local authentication to your project.
gcloud config set project $PROJECT_ID
gcloud auth login
gcloud auth application-default login
  1. Download the GKE PoC Toolkit binary.
mkdir gke-poc-toolkit && cd "$_"
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
  1. Initialize the cli:
./gkekitctl init
  1. Run gkekitctl apply to run the Toolkit. By default, this command sets up a single-cluster GKE environment. (Configuration here). Enter your project ID when prompted.
./gkekitctl apply
# 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.

# 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.

## 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

./gkekitctl delete
