How to Set Up Kubernetes for a Startup

Kubernetes without the platform team - the managed cluster setup that works for 5-50 engineers.

Kubernetes is powerful enough to run Netflix and complex enough to require a dedicated platform team - if you set it up wrong. This guide covers the managed cluster configuration that gives you container orchestration auto-scaling and rolling deployments without requiring a Kubernetes specialist to maintain it.

No fluff. Production-grade answers from engineers who build this every day.

Managed Cluster vs Self-Managed - The Decision

Self-managed Kubernetes (kubeadm k3s on bare metal) makes sense for specific compliance requirements or extreme cost optimization. For 95% of startups its unnecessary complexity. Managed options: EKS (AWS) GKE (Google Cloud) AKS (Azure). GKE is the most mature and developer-friendly. EKS is the right choice if youre already deep in AWS. All three handle the control plane upgrades and most operational complexity.

At Valletta Software, we focus on:

Managed cluster: GKE Autopilot EKS with managed node groups or AKS - dont manage the control plane

Namespace strategy: per-environment (dev staging prod) or per-team - not one flat namespace

Resource requests and limits: always set both - Kubernetes scheduling depends on requests

HPA: Horizontal Pod Autoscaler on CPU and custom metrics - scale on load not manually

RBAC: least privilege - developers get read access CI gets deploy access no cluster-admin in prod

Network policies: deny-all default allow explicitly - microservices should not talk freely

Ingress: nginx-ingress or cloud-native load balancer with TLS termination - not NodePort

The Production Checklist for a Startup Kubernetes Cluster

The things that bite you six months after launch if you skip them.

We give you more than just people. We give you top performers who drive results.

Pod disruption budgets: minimum available pods during node drain - zero-downtime deployments

Secrets: External Secrets Operator with AWS Secrets Manager or HashiCorp Vault - not base64 in YAML

Monitoring: kube-prometheus-stack (Prometheus plus Grafana plus Alertmanager) - one Helm chart

Logging: Fluent Bit to CloudWatch or Loki - structured JSON logs not application-level file writes

Cluster upgrades: test in staging first upgrade control plane then node groups - one minor version at a time

Cost: Spot/Preemptible nodes for non-critical workloads - 60-70% savings on compute

Backup: Velero for cluster state backup - not just database backup

You stay in control. We handle hiring, contracts, and HR. You direct the work.
