Deploy a Kubernetes Cluster on AWS in Under 20 Minutes with SeaGit

Spinning up a production-grade Kubernetes cluster on AWS usually means

juggling VPCs, IAM roles, node groups, and a wall of Terraform. With SeaGit

you can go from zero to a running EKS cluster in under 20 minutes — no prior

Kubernetes expertise required. Here's the full walkthrough.

## What you'll need

- A SeaGit account (free tier works fine)

- An AWS account with permissions to create IAM roles

- About 20 minutes

## Step 1 — Connect your AWS provider (3 min)

In the SeaGit dashboard, go to Providers and click "Connect AWS". SeaGit walks

you through creating a scoped IAM role — copy the generated trust policy into

the AWS console, paste the role ARN back, and you're connected. No long-lived

access keys to manage.

## Step 2 — Create a network (2 min)

Head to Networks and click "New VPC". Pick a region and a CIDR range (the

default 10.0.0.0/16 is fine for most teams). SeaGit provisions the VPC,

public/private subnets across availability zones, and NAT gateways for you.

## Step 3 — Provision the cluster (10 min)

Open Clusters and click "New Cluster":

- Choose the VPC you just created

- Select a Kubernetes version (latest stable is pre-selected)

- Pick a node group instance type — t3.medium is a good starting point

- Set min/max nodes for autoscaling (try 2–4)

Hit Create. SeaGit provisions the EKS control plane, node groups, and core

add-ons (NGINX ingress, the ALB controller, and ArgoCD) automatically. This is

the longest step — grab a coffee while AWS spins up the control plane.

## Step 4 — Deploy your first app (3 min)

Once the cluster shows "Ready", create an Environment (say, "production"), then

add an Application. Point it at your container image, set a port, and deploy.

SeaGit assigns a DNS subdomain, wires up ingress, and rolls out your workload

with zero-downtime defaults.

## That's it

You now have a real EKS cluster — autoscaling nodes, ingress, GitOps delivery,

and your first app live — in under 20 minutes. Everything is provisioned with

infrastructure-as-code under the hood, so it's reproducible and auditable, but

you never had to write a line of Terraform.

Push a commit to your connected repo and watch the CI/CD pipeline deploy an

ephemeral preview environment automatically. Welcome to Kubernetes without the

headache.
