oc Expose Service Examples¶
Introduction¶
oc get routes and oc expose service are used to publish Services outside the cluster. Confirm route host, target service, and endpoints before testing from a browser.
When You Need This Command¶
Use this command when you need to inspect, change, or verify OpenShift resources from the terminal without relying on the web console.
Syntax¶
oc <command> <resource> [name] -n <project>
Practical Examples¶
oc expose service/web -n app
oc get routes -n app
oc describe route web -n app
curl -Ik https://web-app.apps.ocp.example.com
Example output:
NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD
web web-app.apps.ocp.example.com web 8080 None
Verification¶
oc get events -n app --sort-by=.lastTimestamp
oc get pods -n app -o wide
Common Mistakes¶
- Looking only at the final error and ignoring events.
- Checking the wrong project with oc.
- Changing several objects at once before confirming the current state.
Production Notes¶
Run read-only commands first, check the active project, and prefer declarative manifests for repeatable changes.
Quick Checklist¶
- Confirm the active project.
- Inspect the exact object named in the error.
- Read recent events.
- Apply one focused fix.
- Verify status after the change.
