Generated resources
The deploy command creates the following Kubernetes resources:
- Deployment: Manages the specified number of pod replicas running your container image
- Service: Exposes your deployment via a LoadBalancer with the specified port
Both resources are created in the specified namespace and use matching labels for pod selection.
The deployment creates a LoadBalancer service by default. On cloud providers like AWS and GCP, this will provision an external load balancer. For local or on-premises clusters, you may need to configure an ingress controller or use a different service type.
