Setup

  • Make sure Docker is installed
  • Create a Google Cloud account. (You can sign up for a free trial!)
  • Create a Project in Google Cloud Dashboard.

Enable Billing

Make sure billing is enabled for project.

Installing gcloud command line utilities

  # install gcloud
  curl https://sdk.cloud.google.com | bash
  # Restart shell
  exec -l $SHELL
  gcloud components install kubectl
  gcloud --quiet components update

Setup gcloud defaults

gcloud auth login
gcloud config set project <PROJECT_ID>
gcloud config set compute/zone <ZONE>
  • Your PROJECT_ID can be found in your dashboard
  • A Cluster is deployed to a single zone. You can find more about zones here. Or you can select one from the list generated from gcloud compute zones list

Create a Cluster

gcloud container clusters create nsolid-cluster \
 --username admin \
 --password password \
 --num-nodes 3 \
 --machine-type n1-standard-1 \
 --disk-size 80 \
 --enable-cloud-logging \
 --enable-cloud-monitoring \
 --scope "https://www.googleapis.com/auth/devstorage.read_write" \
 --wait
  • Username & Password flags are for accessing your Kubernetes cluster
  • Enable cloud logging & monitoring flags only work if you have enabled them in the dashboard. Logging requires creating a bucket to dump log files to.
  • Scope: Allows your instances to have oauth access to particular parts of the cloud api. In this case devstorage.read_write allows access to buckets.
  • wait blocks the command until cluster and instances are ready. This could take 3-5 minutes.

If you omit the password flag google will create one for you. After your cluster is setup you can find it by

gcloud container clusters describe nsolid-cluster | grep password

Set cluster as default

  gcloud config set container/cluster nsolid-cluster
  # share credentials with kubectl
  gcloud container clusters get-credentials nsolid-cluster

Accessing your Kubernetes dashboard

kubectl cluster-info

The master url will provide you with a list of resource like the ui, swagger, logs, metrics, health, and api.
