Fix incorrect terminal commands in API Platform Documentation

[VidathVi]

Purpose

Found four issues in the kubernetes standalone gateway deployment guide (https://wso2.com/api-platform/docs/api-gateway/1.1.0/deployment/deployment-modes/kubernetes/kubernetes-standalone/) while following the page's instructions on a local "kind" cluster and fixed them.

• Not applicable — no images added or changed
• Not applicable — existing frontmatter unchanged

Goals

Make sure documented commands work exactly as written for anyone following the guide from scratch on a local development cluster, without running into errors in the terminal.

Approach

Fixed four command line commands in

1. Corrected the port of the health-check example from 9094 (which wasn't mapped) to 9090.
2. Added the "-u admin:admin" flag to the same health check example because it doesn't work without this authentication. (It still doesn't work even with this authentication, but at least it gives a 404 page not found response instead of the terminal running into an error)
3. Added a new "Expose the data plane" step before "Test routing through the gateway" step
4. Added a note clarifying that the, "helm install" sections of "Install Gateway Chart" and "TLS Configuration" must be combined into a single install, because running them one after the other would lead to a release name conflict (or run via helm upgrade if running sequentially).

User stories

As a developer following this guide for the first time, it would be nice to have all the docummented commands work as written. This would save the time wasted on figuring out and fixing these issues.

Release note

Fixed incorrect port, missing authentication, a missing port-forward step,
and conflicting install/TLS instructions in the Kubernetes standalone
gateway deployment guide.

Test environment

Windows 11, local kind Kubernetes cluster, kubectl, Helm 3.x,
gateway Helm chart gateway-1.1.5 (app.kubernetes.io/version: 1.1.0),
cert-manager (Jetstack) for TLS. All four fixes verified by reproducing
the original failures, then confirming the corrected commands succeed.

Learning

Every issue was found by hitting an actual command line failure while working on a personal project while following the WSO2 kubernetes standalone gateway guide step by step. And then inspecting cluster states to find the fix

📝 Walkthrough

Walkthrough

The Kubernetes standalone deployment guide updates Helm instructions, changes the controller health check to authenticated port 9090, and adds gateway runtime service port-forwarding steps for data-plane testing.

Changes

Kubernetes standalone documentation

Layer / File(s)	Summary
Helm upgrade guidance en/docs/api-gateway/1.1.0/deployment/deployment-modes/kubernetes/kubernetes-standalone.md	The guide instructs users to use helm upgrade when the gateway is already installed.
Controller health check en/docs/api-gateway/1.1.0/deployment/deployment-modes/kubernetes/kubernetes-standalone.md	The controller health check uses authenticated port 9090 instead of unauthenticated port 9094.
Runtime service testing en/docs/api-gateway/1.1.0/deployment/deployment-modes/kubernetes/kubernetes-standalone.md	The guide adds commands to identify the gateway runtime service and port-forward HTTP 8080 and HTTPS 8443.

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title is overly broad and does not clearly identify the primary fix. It mentions 'incorrect terminal commands' but the PR actually fixes four distinct issues including a port change, missing authentication, a missing step, and conflicting install instructions.	Revise the title to be more specific about the main changes, such as 'Fix health check port, authentication, and Helm install instructions in Kubernetes deployment guide'.
