A helper scrip to spin up GKE clusters

gke-install.sh

#!/usr/bin/env sh

# This script lives in ~/bin
# It mostly automates the instructions found on https://heptio.github.io/ark/v0.9.0/gcp-config, except that creating the bucket and service account has already been done.

# Source the variables since they're private information
# Defines $PROJECT, $CREDS_FILE, $SERVICE_ACCOUNT_EMAIL, and $BUCKET.
source ~/bin/gke-vars.sh

# Spin up a GKE cluster and get the credentials for kubeconfig

# TODO: update with BackupStorageLocation

# Only apply the deployment file if -d switch is provided. Otherwise, we'll run Ark locally.

# When done, I delete the cluster with:
#    gcloud container clusters delete cluster-1 --async
# --async can be left off if you want to wait for the cluster to teardown.

# TODO: Script to gather all snapshots and delete them, since those can add up.
