Starting Cluster Creation

To create a cluster start the script deploy.sh

You should especify one environment:

• nonprod
• mgmt
• prod

./deploy.sh nonprod|mgmt|prod

If you choose the prod option, the script will ask to you in which aws region must be placed this new cluster:

• 1. eu-west-1

Next Steps

The script will automatically create the following:

• Update trust relationship roles to k8s nodes role
• Create helm service account
• Apply RBAC to helm service account
• Initialize helm
• Deploy ALB Controller
• Deploy keel

Get cluster access

To get access to a cluster, use the command:

eksctl utils write-kubeconfig --name cluster-name

Deploying Demo

kubectl apply -f resources/demo.yaml

** PS: This demo is using nonprod cluster settings, if you want to use in another cluster please remember to change the fields at the ingress section:

• alb.ingress.kubernetes.io/subnets: #nonprod DMZ subnets

• `alb.ingress.kubernetes.io/certificate-arn: "arn:aws:acm:eu-west-1"

• - host: www.example.com

Cleanup

Delete cluster

CLUSTER_NAME="nonprod"
helm delete nginx-ingress --purge
kubectl delete ingress,svc,deployment nginx
eksctl delete cluster --name ${CLUSTER_NAME}
