Creating a Kubernetes Cluster

Search…
Below you will find examples of creating a small 3 node Kubernetes cluster to try NATS on multiple clouds.
Google Kubernetes Engine
Use gcloud to create a 3 node regional Kubernetes cluster on us-west2.
1
# Create a 3 node Kubernetes cluster. One node in each of the region's three zones.
2
gcloud container clusters create nats-k8s-cluster \
3
  --project $YOUR_GOOGLE_CLOUD_PROJECT \
4
  --region us-west2 \
5
  --num-nodes 1 \
6
  --machine-type n1-standard-2
Copied!
Note that since this is a regional cluster we are specifying --num-nodes 1 which will create a kubelet on 3 different zones. If you are creating a single-zone cluster but want 3 nodes then you have to specify --num-nodes 3.
Amazon Kubernetes Service
The eksctl is a very helpful tool to manage EKS clusters, you can find more docs on how to set it up here.
1
# Create 3 node Kubernetes cluster
2
eksctl create cluster --name nats-k8s-cluster \
3
  --nodes 3 \
4
  --node-type=t3.large \
5
  --region=eu-west-1

# Get the credentials for your cluster
8
eksctl utils write-kubeconfig --name $YOUR_EKS_NAME --region eu-west-1

You can use doctl to create a cluster as follows:
1
doctl kubernetes cluster create nats-k8s-nyc2 --count 3 --region nyc1
Copied!
Azure Kubernetes Service
Using az you can create a cluster like this:
1
# In case not done already, register to use some services:
2
az login
3
az provider register -n Microsoft.Network
4
az provider register -n Microsoft.Storage
5
az provider register -n Microsoft.Compute
6
az provider register -n Microsoft.ContainerService

8
# Create resource group and 3 node cluster
9
az group create --name nats --location westus
10
az aks create \
11
    --resource-group nats \
12
    --name nats  \
13
    --node-count 3 \
14
    --node-vm-size Standard_DS2_v2 \
15
    --load-balancer-sku basic \
16
    --enable-node-public-ip 
17
​
18
az aks get-credentials --resource-group nats --name nats
Copied!
Eventually your cluster will be provided ExternalIPs that the NATS cluster can advertise to clients:
1
kubectl get nodes -o wide
2
NAME                       STATUS   ROLES   AGE     VERSION    INTERNAL-IP   EXTERNAL-IP      OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME
