To make an application accessible outside the Kubernetes cluster, several methods can be used:

Service of type LoadBalancer — creates an external load balancer (if supported by the cloud provider) that directs traffic to the pods.
NodePort — opens a fixed port on each cluster node, which can be accessed from outside the cluster.
Ingress — an object that manages external access to services within the cluster, usually via HTTP/HTTPS, with routing and SSL configuration options.
External IP — assigning an external IP address to a service (for example, in some clouds or using MetalLB).

Example of using Ingress:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: my-service
            port:
              number: 80

Thus, the choice of method depends on the infrastructure and access requirements.
