Kubernetes for Startups: What You Actually Need

Do you actually need Kubernetes?

Before anything else — let's be honest. Kubernetes is powerful, but it's also complex. If you have fewer than 5 microservices and a team of under 10 engineers, you probably don't need it yet.

That said, if you're building a product that will scale, or you're already feeling the pain of manual deployments and inconsistent environments, it's time to talk about Kubernetes.

What a startup cluster actually needs

Most "Kubernetes setup" guides show you everything. Here's what you actually need to start:

1. A managed control plane

Don't self-host your control plane. Use EKS (AWS), GKE (Google Cloud), or AKS (Azure). The managed control plane cost ($70–150/month) is worth it to avoid debugging etcd at 2am.

2. Node groups that make sense

3. GitOps from day one

Set up ArgoCD before you deploy your first service. Deploying via `kubectl apply` manually is a trap — it works until it doesn't, and you have no audit trail.

# Example ArgoCD Application

apiVersion: argoproj.io/v1alpha1

kind: Application

metadata:

name: my-service

namespace: argocd

spec:

project: default

source:

repoURL: https://github.com/your-org/gitops-repo

targetRevision: main

path: apps/my-service

destination:

server: https://kubernetes.default.svc

namespace: production

syncPolicy:

automated:

prune: true

selfHeal: true

4. Resource limits on everything

Every pod needs `requests` and `limits`. Without them, one noisy neighbour can take down your whole node.

resources:

requests:

memory: "128Mi"

cpu: "100m"

limits:

memory: "256Mi"

cpu: "500m"

5. Basic observability

Prometheus + Grafana with the `kube-prometheus-stack` Helm chart. 30 minutes to set up, saves hours of debugging.

What you can skip at first

The honest truth about Kubernetes

It takes 2–4 weeks to set up properly. The first week you'll wonder if it was worth it. By month 3, you won't be able to imagine deploying any other way.

The key is doing it right the first time — GitOps, resource limits, observability, and RBAC. Skipping these creates technical debt that's painful to fix later.
