gcloud cheatsheet for GKE

This is by no means comprehensive, it's just some things I've found useful.

Get installed and auth'd:
gcloud components install kubectl
gcloud auth application-default login
Creating a cluster with a specific version:
gcloud config set compute/zone us-west1-b
gcloud beta container clusters create permissions-test-cluster \
    --cluster-version=1.6.1 \
    --no-enable-legacy-authorization
Upgrading GKE:
# Get available versions
$ gcloud container get-server-config 
Fetching server config for us-west1-b
defaultClusterVersion: 1.5.7
defaultImageType: COS
validImageTypes:
- COS
- CONTAINER_VM
validMasterVersions:
- 1.6.4
- 1.5.7
validNodeVersions:
- 1.6.4
- 1.6.2
- 1.5.7
- 1.5.6
- 1.4.9

$ CLUSTER_NAME="testing"
$ CLUSTER_VERSION="1.6.4"

# Nodes
$ gcloud container clusters upgrade $CLUSTER_NAME --cluster-version=$CLUSTER_VERSION

# Master
$ gcloud container clusters upgrade $CLUSTER_NAME --master --cluster-version=$CLUSTER_VERSION
