Network Path Analysis for OKE

The problem

Organizations leveraging Oracle Container Engine for Kubernetes (OKE) often face challenges ensuring that their network configurations are properly set up to support cluster deployment and operation. OKE clusters depend on specific networking prerequisites—such as subnets, security lists, routing tables, and load balancer settings—that must be correctly configured in advance. However, these configurations can be complex, vary across environments, and are prone to human error.

When network settings are misconfigured, OKE clusters fail to provision or function as intended, leading to wasted engineering time, troubleshooting delays, and disruptions in application delivery. This lack of an automated way to validate network readiness before cluster creation introduces significant operational risks and slows down development velocity.

To address this issue, there is a need for a reliable solution that can test and verify required network configurations prior to OKE cluster deployment. Such a solution would ensure compliance with OKE requirements, provide actionable feedback to engineers, and reduce failures during provisioning—ultimately enabling faster, more secure, and more predictable Kubernetes operations in the cloud.

My impact

• Held collaboration sessions with networking and OKE architects to better understand the different OKE configurations that a customer would commonly need to test for connectivity.


• Created user flows to show the process for creating a Network Path Analyzer test from the OKE cluster.


• Designed simplistic pre-configured source and destination tests for customers to validate their OKE cluster functionality.


• Used the Network resource design system to show hop by hop data.


• Validated numerous configuration tests with networking and OKE architects and engineers.

Meaningful results

Network Path Analyzer (NPA) tests significantly reduce support tickets for Oracle Container Engine for Kubernetes (OKE) by proactively validating critical network configurations before cluster provisioning or workload deployment.

This self-service validation not only accelerates troubleshooting and increases customer confidence but also decreases the number of network-related support requests submitted to the cloud provider. As a result, NPA tests improve the overall reliability of OKE deployments, streamline customer operations, and free up support teams to focus on more complex issues as covered in Network troubleshooting for OCI Container Engine for Kubernetes clusters.
