Deploy AWS k8s cluster

Prerequisities before running the AWS k8s cluster deployment:

• a fresh EC2 Ubuntu instance on AWS
• an IAM user/role with Route53, EC2, IAM and S3 full access and attached to the EC2 instance
• a Route53 private hosted zone, following example uses domain "appstacleoulu.fi" on eu-west-3 region

SSH to your cluster and follow this instruction:

First, root the instnace:

sudo su -
export KOPS_STATE_STORE=s3://dev.k8s.appstacleoulu.fi

in directory: Eclipse-Hono-on-AWS-and-Azure

chmod +x AWS_k8s.sh
./AWS_k8s.sh

Enter your EC2 instance zone when it is required.

Finally, create kubernetes cluser:

kops update cluster dev.k8s.appstacleoulu.fi --yes

It takes 5-10 min to create the AWS k8s cluster.

To validate your cluster:

kops validate cluster

And to list nodes:

kubectl get nodes

To access the K8s master node:

cd .ssh
ssh -i id_rsa admin@(Public DNS)

To delete the k8s cluster:

export KOPS_STATE_STORE=s3://dev.k8s.appstacleoulu.fi
kops delete cluster dev.k8s.appstacleoulu.fi --yes

Deploy Azure k8s cluster

Prerequisites

• an Azure subscription
• Azure CLI installed to setup the infrastructure.

login to your Azure CLI and root..

sudo su -

in directory: Eclipse-Hono-on-AWS-and-Azure

Then..

chmod +x Azure_k8s.sh
./Azure_k8s.sh

If encountered error, run following scripts again:

az aks create --resource-group oulu --name azure --node-count 2 --generate-ssh-keys
az aks install-cli
az aks get-credentials --resource-group oulu --name azure

It takes 5-10 minutes before it creates the cluster node. To list nodes and get cluster info

kubectl get nodes
kubectl cluster-info

Deploying the Eclipse Hono on the AWS/Azure k8s clusters:

chmod +x Hono_deployment.sh
./Hono_deployment.sh

To get Hono services, pods, and endpoints

kubectl get pods,svc,ep -n hono

To describe the pod and get logs. (Note: Replace "..." with your specific pod name.)

kubectl describe pod ... -n hono
kubectl -n hono logs ...
