Como usar: Kubernetes YAML Generator
- Enter the app name, namespace, container image (with a pinned tag), replicas and the port your app listens on.
- Tick the objects you need — Service, Ingress, ConfigMap, Secret, autoscaling — and fill in their options.
- Keep resource limits, probes and secure pod settings on for production; adjust the values to your app.
- Copy or download the YAML and run
kubectl apply -f. Check it first with the Kubernetes YAML Validator.
What the manifest contains
| Object | What it does |
|---|---|
| Deployment | Runs your container with the given replicas, a rolling-update strategy, labels that match the Service selector, resources and probes |
| Service | A stable address for the pods — ClusterIP inside the cluster, NodePort or LoadBalancer to expose it |
| Ingress | Routes a host name (and path) to the Service; with cert-manager it requests a Let’s Encrypt certificate automatically |
| ConfigMap / Secret | Environment variables loaded with envFrom; secrets use stringData placeholders you replace (or manage with Sealed Secrets / External Secrets) |
| HPA | Scales replicas between a minimum and maximum to keep average CPU near the target |
Secure pod settings
The security context runs the container as a non-root user, blocks privilege escalation, drops all Linux capabilities, uses the default seccomp profile and mounts the root filesystem read-only (with a writable /tmp). These are the settings the Kubernetes “restricted” Pod Security Standard expects. If your app must write elsewhere, mount an emptyDir there.

Perguntas frequentes
How do I create a Kubernetes deployment YAML?
Enter the app name, image and port here and copy the Deployment. It includes labels, a selector, replicas, resources and probes — then apply it with kubectl apply -f.
Why do the Service selector and pod labels matter?
A Service sends traffic to pods whose labels match its selector. The generator uses the same app.kubernetes.io/name label in both, so they always match.
How do I get HTTPS on an Ingress?
Install cert-manager with a ClusterIssuer (for example letsencrypt-prod), tick TLS, and the Ingress annotation tells cert-manager to issue and renew the certificate.
Should I set resource limits?
Yes. Requests let the scheduler place pods sensibly and limits stop one pod from starving others. Autoscaling also needs CPU requests to calculate usage.
Posso instalar o Kubernetes YAML Generator como um aplicativo da web e usá-lo offline?
Sim. O Kubernetes YAML Generator é um aplicativo da web instalável (PWA) — instalado a partir do seu navegador, não baixado de uma loja de aplicativos. Clique em “Instalar aplicativo” na parte superior desta página no Chrome ou no Edge (Windows, macOS, Linux, ChromeOS) ou, no Android, use “Compartilhar” → “Adicionar à tela inicial” no iPhone e no iPad, ou “Arquivo” → “Adicionar ao Dock” no Safari 17+ em um Mac. Em seguida, ela se abre em uma janela própria com seu próprio ícone e, como é executada inteiramente no seu navegador, continua funcionando offline. O Firefox no desktop não permite a instalação de aplicativos da web. Como funciona a instalação.
