Starting stack on AWS

What actually gets provisioned during Quick Start


  1. VPC in the region that was picked. Along with the VPC, private and public subnets are also provisioned with dedicated subnets for any databases you might want to provision. These are associated with security groups, ingress and egress rules, public IPs and EIPs. This spans across 3 AZs.
  2. EKS - a kubernetes cluster with a single managed nodegroup that can scale up and down within the specified limits. The nodes (EC2 instances) are provisioned through an ASG (Auto-Scaling Group). This can be used to provision on-demand instances or spot instances for cost savings in non-critical environments. By default, EBS is used for storage (the default is going to change to EFS for cross-AZ access)
  3. Loadbalancer - A single NLB is used per cluster. This is to provide maximum flexibility for services to be exposed on different endpoints and ports (eg, two different services on and tcp:// This loadbalancer is provisioned through the ingress-nginx controller.


These services are provisioned by default:

  1. Prometheus for metric collection
  2. cert-manager for provisioning letsencrypt TLS certificates
  3. cluster-autoscaler to scale the ASGs based on load, within limits
  4. node-exporter and event-exporter for logging kubernetes cluster specific diagnostics
