Your Startup Needs a Deployment Platform, Not a Platform Team

· 8 min read

Many startups begin with one application and a hosted deployment service. That is usually the right decision. The team can ship without first building networking, deployment automation, or an operations layer.

The requirements change as the company adds services, environments, enterprise customers, private networking, and infrastructure ownership. The team still needs a short path to production, but the applications now need to run in infrastructure the company controls.

AstroPulse gives growing engineering teams a repeatable path from code to production in infrastructure they control, without requiring them to build the platform themselves.

From code in an editor through Astro Platform services to a healthy application, with one platform reused across multiple services

Push to Your Own Domain: Managed Add-ons + Custom Domains

TL;DR

Our earlier build-your-own-PaaS blueprint wired up ingress, TLS, and DNS by hand. Now it's three managed add-ons and one domain verification: install NGINX + cert-manager + ExternalDNS, verify a domain once, and every container image you deploy comes up on your own domain with real, auto-renewing HTTPS. Do it from the console, the CLI, or just ask your AI. All three drive the same platform.

The AstroPulse console — clusters, applications, add-ons, and domains in one place

Three ways to follow along. Each step below leads with the console walkthrough, with the CLI and AI equivalents in the tabs underneath:

  • Console: point and click; the walkthroughs below are the real UI.
  • CLI: astroctl …, copy-paste ready.
  • AI: ask Nova in the console, or connect your editor's assistant to the AstroPulse MCP (platform.astropulse.io/mcp) and describe what you want. For building an image straight from a repo, the astro-deploy MCP does that too.

Before you start: one cluster with cloud identity

You need exactly one thing: a Kubernetes cluster connected to AstroPulse, running with the cloud's own identity — IRSA on AWS, Workload Identity on GCP/Azure. That identity is what lets ExternalDNS manage DNS and cert-manager solve ACME challenges without ever handling a cloud credential.

The easy path is to let AstroPulse provision the cluster. It wires that identity up for you:

Connect your cloud, then provision (identity configured for you)
$ # one-time: connect your cloud account astroctl cloud aws connect --account-id 123456789012 --region us-east-1 --cluster-name prod # provision the cluster — IRSA / Workload Identity is set up automatically astroctl infra k8s apply -f cluster.yaml

Already run your own cluster? Register it instead, then set up the identity per the add-on docs:

Terminal
$ astroctl infra k8s register --cluster-name my-cluster

Step 1: Install the three add-ons

On your cluster's Add-ons tab, choose Install Add-on and pick from the catalog. Each installs with production-sensible defaults; you tune only what matters.

Installing an add-on from the catalog — pick it, review the defaults, install
  • NGINX Ingress: routes public traffic. The default terminates TLS at the ingress (there's a passthrough option for backends that terminate their own). On a cloud cluster it comes up behind a real LoadBalancer with the right provider annotations already set.
  • cert-manager: issues and renews TLS certificates. Turn on Create a Let's Encrypt ClusterIssuer and add a contact email for real, auto-renewing public certificates, with no manual cert wrangling.
  • ExternalDNS: publishes DNS records for your apps. Pick your DNS provider and set the domain filter to your zone (e.g. example.com). It uses the cluster identity from the prerequisite step, so no keys are ever stored.

Prefer YAML? The same add-ons apply declaratively. Copy-paste the example manifests:

Apply add-ons and watch them go healthy
$ astroctl infra k8s addons apply -f nginx-ingress.yaml astroctl infra k8s addons apply -f cert-manager.yaml astroctl infra k8s addons apply -f external-dns.yaml astroctl infra k8s addons get prod # all add-ons + health

Installed together, they compose into automatic, production-grade HTTPS: cert-manager solves the ACME challenge through NGINX, ExternalDNS creates the DNS record, and NGINX terminates TLS at the edge with the issued certificate. Certificates renew themselves.

Step 2: Verify your domain, once

In Settings → Domains, add a domain you control and publish the TXT record it shows you. Once it verifies, every internet-facing app can serve on it, on a hostname you choose (shop.example.com) or an auto-generated one.

Adding a domain, publishing the TXT record, and watching it verify
Claim and verify a domain
$ astroctl domain add example.com # prints the TXT record to publish astroctl domain verify example.com # run once DNS has propagated

See Custom Domains for the details.

Step 3: Deploy a container image on your domain

Custom domains attach to Container Image applications; that's the exposure model. Here's a ready-made image so you can watch the whole thing light up:

Deploy wizard: Container Image astropulse/latency:v1.0.0, then choose a verified domain and hostname under External access
  1. Deploy Application → Container Image, image astropulse/latency:v1.0.0.
  2. Under External access, pick your verified domain and a hostname (or leave it blank to auto-generate <app>-<id>.example.com).
  3. Deploy.

Within a minute or two the app is running, its DNS record and TLS certificate are created for you, and it's live on https://<your-host>.example.com.

Deploy an image app on a verified domain
$ cat <<'EOF' | astroctl app apply -f - apiVersion: platform.astropulse.io/v1 kind: Application spec: name: latency-demo profileName: <YOUR_PROFILE_NAME> # list: astroctl app profile get source: type: image image: registry: docker.io repository: astropulse/latency tag: v1.0.0 externalAccess: domain: example.com # verified domain → latency-demo-<id>.example.com EOF

Test it locally: no cloud needed

Want to validate the wiring before touching a cloud account? The whole flow runs on a local kind cluster, with a few local swaps:

  • NGINX: install it with Expose via NodePort (Advanced settings). kind has no cloud LoadBalancer, so the controller is reachable on a node port instead. That's the only local-vs-cloud difference.
  • cert-manager: enable a self-signed ClusterIssuer: no ACME account, no public DNS, no email. It's Ready offline, which is all you need to prove the TLS path.
  • ExternalDNS: skip it locally; it needs a real cloud DNS zone.

Deploy any container image with an ingressClassName: nginx Ingress and it's reachable through NGINX exactly as it would be through a cloud LoadBalancer in production. Full steps are in the add-on docs' local testing section.

The point

The blueprint still stands if you want to own every piece. But the ingress, TLS, and DNS plumbing is now something AstroPulse installs, keeps healthy, and upgrades for you, reachable from a console, a CLI, or a sentence to your AI. Push an image, get a live URL on your own domain with real HTTPS. That's the whole idea.

From Git Push to Production: Your Own Self-Hosted Platform

TL;DR: What You'll Build

In this guide, you'll build your own Vercel-like platform on Kubernetes in ~30 minutes:

  • You'll deploy an EKS cluster with kpack (auto-builds), cert-manager (TLS), external-dns (DNS), and nginx-ingress
  • You'll configure automatic Git push → build → live HTTPS deployment (just like Vercel)
  • You'll run any workload: web apps, APIs, databases, microservices, background jobs—any language
  • You'll add security scanning, compliance controls, and observability for production
  • You'll use Nova to debug, troubleshoot, and operate your platform

Perfect for building internal developer platforms, launching SaaS products, or meeting enterprise compliance requirements.

Introduction

You want the simplicity of "push code, get a live URL"—the developer experience Vercel pioneered—but with full control over your deployment, infrastructure, and compliance. This guide shows you how to build that experience on your own AWS infrastructure using AstroPulse and open-source tools: kpack, cert-manager, external-dns, and nginx-ingress.

AstroPulse PaaS Flow Architecture

You'll build a production-grade platform that delivers Git-push deployments with automatic TLS certificates, preview URLs, and complete observability—all running on infrastructure you own and control. Unlike hosted PaaS platforms, you'll be building on Kubernetes with full deployment control. That means you can run any workload: microservices (with or without public endpoints), stateful databases, WebSockets, long-running background jobs, AI/ML model training and serving, or traditional web applications in any language. You get the simple developer experience with complete architectural control.

How operations work: The infrastructure industry is moving toward an agentic era—AI agents autonomously handling complex workflows (MCP, A2A, multi-agent orchestration). We're heading toward infrastructure that self-configures, self-heals, and self-optimizes. We're not there yet, but Nova brings you AI-assisted operations today with human-in-the-loop. Day 1 (this guide): You build the platform. Day 2 (ongoing): Nova analyzes issues, diagnoses problems, recommends fixes—you approve. As AI matures, more becomes autonomous.
