Google Kubernetes Engine (GKE)

This module can be used to install dependencies for Google Kubernetes Engine (GKE) provisioning (the gcloud cli), provision a GKE cluster, and destroy an GKE cluster provisioned using this utility.

Getting Started

Optionally run install.sh, this only works on MacOS and Fedora-based Linux instances.

Provisioning

  1. Set the following env vars before provisioning:
export GCLOUD_CREDS_FILE=<your-gcloud-json-key-file, usually ~/.gcp/osServiceAccount.json> (this will default to ~/.gcp/osServiceAccount.json so its not technically required)
export GCLOUD_PROJECT_ID=<your-gcloud-project-id>

# Optional
export CLUSTER_NAME=<some cluster name> # if you set a cluster name, we will use it as a base name for all resources created and append a unique identifier
# if CLUSTER_NAME is not specified, we will use the first 8 characters of the system's username

export GCLOUD_NODE_COUNT=<desired node count>
export GCLOUD_REGION=<desired region>         # defaults to us-east1
export GCLOUD_CLUSTER_VERSION
export GCLOUD_CLUSTER_CHANNEL                 # defaults to use regular channel
  1. run ./provision.sh
  2. if successful, you will see a .json and .kubeconfig file with metadata for your cluster!

Cleaning up a cluster

  1. run ./destroy.sh <.json file of your cluster metadata>
