What the lab teaches
The lab teaches how to use the OpenShift web console to deploy an application directly from a public container image repository. It uses the Deploy Image flow in the Developer perspective, where OpenShift pulls the container image and creates a running application from it.
Prerequisites covered
Learners should understand:
| Topic | Why it matters |
|---|---|
| Container images | The app is deployed from an existing image |
| Container image repositories | The image is pulled from a registry such as Quay |
| OpenShift web console | The lab uses the UI, not CLI |
| Administrator and Developer perspectives | Learners navigate the Developer +Add workflow |
| OpenShift and Kubernetes relationship | OpenShift runs the container workload on Kubernetes |
Main lab flow
| Step | Action |
|---|---|
| 1 | Open the Developer Sandbox |
| 2 | Log in with a Red Hat account |
| 3 | Open the OpenShift web console |
| 4 | Go to Developer perspective |
| 5 | Click +Add |
| 6 | Select Container images |
| 7 | Open the Deploy Image tab |
| 8 | Enter image name: quay.io/openshiftroadshow/parksmap:1.3.0 |
| 9 | Select Deployment as the resource type |
| 10 | Click Create |
| 11 | View the app in the Topology page |
| 12 | Open the app using the URL icon |
| 13 | Delete the application from Topology |
| 14 | Confirm deletion by entering the application name |
What OpenShift creates
When the image is deployed, OpenShift downloads the container image and creates a running containerized application in the cluster. For a web application, OpenShift can expose it through a URL/route so the user can open it in a browser.
CLI equivalent for the same lab
The PDF uses the web console, but the closest oc equivalent is:
oc new-project parksmap-demo
oc new-app quay.io/openshiftroadshow/parksmap:1.3.0 --name=parksmap
oc expose service/parksmap
oc get pods
oc get service
oc get route
Code language: JavaScript (javascript)To test the route:
curl -I http://$(oc get route parksmap -o jsonpath='{.spec.host}')
Code language: JavaScript (javascript)To clean up:
oc delete all -l app=parksmap
oc delete route parksmap
oc delete project parksmap-demo
Code language: JavaScript (javascript)Main difference from Lab 2: Lab 2 builds an app from GitHub source code using S2I; Lab 3 deploys a prebuilt container image from a registry.

The tutorial explains how to deploy applications from a container image repository through the OpenShift web console, but it would be useful to include some operational best practices. In real-world environments, managing access to private registries, handling image pull credentials, and enforcing image verification policies are important for maintaining a secure platform. It would also add value to discuss automated image updates, security scanning, and promotion mechanisms that help teams deliver consistent releases across multiple environments.
