Understanding How Applications Are Exposed in Oracle Kubernetes Engine
Summary:
Best Practices for Exposing Web Applications on Oracle Kubernetes Engine (OKE)
Content (please ensure you mask any confidential information):
While working with Oracle Kubernetes Engine (OKE), I explored different approaches for exposing web applications running inside the Kubernetes cluster.
In a typical OKE deployment, applications are deployed using Kubernetes Deployments that run multiple replicas of application pods across worker nodes. These pods are exposed internally using a Kubernetes Service which provides a stable endpoint for communication inside the cluster.
For external access, one commonly used approach is creating a Service of type LoadBalancer. In Oracle Kubernetes Engine, this automatically provisions an OCI Load Balancer that routes external traffic to the Kubernetes service.
