Which sequence describes a typical end-to-end deployment flow for a simple OpenShift app from source to exposure to users?

• A. Build from source (BuildConfig), create ImageStream, deploy via Deployment/DeploymentConfig, expose via Route, test via URL, monitor and adjust.
• B. Create Route, then test via URL, then build from source.
• C. Deploy a prebuilt image, forget BuildConfig.
• D. Use Helm to manage deployment exclusively.

Answer: (A)

In OpenShift, the end-to-end flow starts by turning your source code into a runnable container image, then deploying that image and exposing it to users. You begin with a BuildConfig to build the application from source, producing a container image and tagging it in an ImageStream. Once the image is available, a Deployment or DeploymentConfig uses that image to run pods in the cluster. To make the app reachable from outside the cluster, you expose it with a Route, which provides a URL that users can navigate to. After exposing it, you test the app by hitting that URL, observe how it behaves, and then monitor and adjust resources, scaling, or configuration as needed.

This sequence is the standard, end-to-end OpenShift workflow: build from source → image is stored/tracked → deploy the image → expose via a Route → test via the route URL → monitor and refine. Options that skip building from source, start by exposing before a deployment exists, or rely solely on tools like Helm for exclusive management don’t capture the complete path from code to customer-facing access in OpenShift.
