Setup Kubernetes Cluster

Summary

In this lab, you will create a new Kubernetes cluster, which we’ll use for the rest of the lab.

Prerequisites

  • Use either Google Cloud Shell or your terminal with Google Cloud SDK installed (the SDK comes with kubectl, so you do not need to install it manually)

  • You already created a GCP project and set the $PROJECT_ID envrionement variable.

  • You already cloned the directory : https://github.com/Sfeir/kubernetes-istio-workshop.

Run the following commands to configure gcloud, this will save you from typing the parameters $PROJECT_ID, zone or region in every gcloud command.

gcloud config set compute/zone europe-west1-b
gcloud config set compute/region europe-west1
gcloud config set project $PROJECT_ID

  • All the commands must be run in the kubernetes-istio-workshop directory.

Create the cluster

Create a cluster:

$ gcloud beta container clusters create "istio-workshop"

kubeconfig entry generated for istio-workshop.
NAME            LOCATION        MASTER_VERSION  MASTER_IP      MACHINE_TYPE   NODE_VERSION  NUM_NODES  STATUS
istio-workshop  europe-west1-b  1.13.7-gke.8    35.240.33.159  n1-standard-1  1.13.7-gke.8  3          RUNNING

⏳ Wait until the cluster is created. It may takes up to 5 minues.

Connect to the cluster

Let’s check the connexion to our newly created cluster:

1- Review the cluster’s informations:

$ gcloud container clusters list

NAME           LOCATION        MASTER_VERSION  MASTER_IP      MACHINE_TYPE   NODE_VERSION  NUM_NODES  STATUS
istio-cluster  europe-west1-b  1.9.7-gke.6     35.195.237.45  n1-standard-1  1.9.7-gke.6   3          RUNNING

2- Download the cluster’s credentials, they will be written to kubectl's configuration file (~/.kube/config`).

$ gcloud container clusters get-credentials istio-workshop

Fetching cluster endpoint and auth data.

3- Check the connexion with the cluster:

$ kubectl cluster-info

Kubernetes master is running at https://35.184.85.239
GLBCDefaultBackend is running at https://35.184.85.239/api/v1/namespaces/kube-system/services/default-http-backend:http/proxy
Heapster is running at https://35.184.85.239/api/v1/namespaces/kube-system/services/heapster/proxy
KubeDNS is running at https://35.184.85.239/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
Metrics-server is running at https://35.184.85.239/api/v1/namespaces/kube-system/services/https:metrics-server:/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

Now you are ready to install Istio!
