Frequently Asked Questions
About K8s Generator
Can I apply the generated YAML directly with kubectl?
Yes — the generated YAML uses standard Kubernetes API versions (apps/v1 for Deployment, v1 for Service and ConfigMap) and valid field names. Copy the output to a .yaml file and run
kubectl apply -f file.yaml. The Deployment uses matchLabels selectors, the Service includes proper selector mapping, and the ConfigMap follows the standard data format. Always validate with kubectl apply --dry-run=client first in production environments.What Service types are supported?
The Service generator supports three types: ClusterIP (internal-only, default), NodePort (exposes on a static port on each node, range 30000-32767), and LoadBalancer (provisions an external load balancer, cloud-provider dependent). Ingress is not yet included as a generator mode. For production Ingress resources, add an external-dns annotation and a cert-manager integration manually to the generated Service before creating the Ingress separately.

How do I add environment variables, resource limits, or volume mounts?
The Deployment form includes dynamic rows for environment variables (key-value pairs added inline), resource limits (expandable section with CPU/memory request and limit fields), and volume mounts. Each env var generates an
env: entry under the container spec. Resource limits generate a resources: block. The dynamic form allows adding or removing entries — changes reflect immediately in the YAML preview.Does this tool support StatefulSet, DaemonSet, or Job resources?
Currently, the generator supports Deployment, Service, and ConfigMap — the three most commonly used resource types. StatefulSets (for stateful workloads like databases), DaemonSets (for per-node agents), and Jobs/CronJobs (for batch processing) have different spec structures and are planned for future updates. In the meantime, you can generate a Deployment and manually change
kind: Deployment to kind: StatefulSet in the output as a starting point.How should I handle multi-environment configurations (dev/staging/prod)?
Generate a base Deployment YAML, then use different ConfigMaps per environment for environment-specific values (database URLs, API keys, feature flags). Apply the same Deployment across namespaces with
kubectl apply -f deployment.yaml -n dev and -n prod. For more advanced management, use Kustomize or Helm to overlay environment-specific patches on the generated base YAML. The generator output serves as the starting point.
