Find the URL for your Argo CD dashboard and log in using your OpenShift credentials
```
oc get route argocd-server -n bgd -o jsonpath='{.spec.host}{"\n"}'
```
Click on the Application to show its topology
Verify that OpenShift sees the Deployment as rolled out
```
oc rollout status deploy/bgd
```

Get the route and browse to it in your browser

oc get route bgd -n bgd -o jsonpath='{.spec.host}{"\n"}'

You should see a green box in the website like so

Patch the OpenShift resource to force it to be out of sync with git

oc patch deploy/bgd --type='json' \
  -p='[{"op": "replace", "path":
  "/spec/template/spec/containers/0/env/0/value", "value":"blue"}]'

Refresh Your browser and you should see a blue box in the website like so
Meanwhile check ArgoCD it should show the application as out of sync. Click the Sync button to have it revert the change you made in OpenShift
Check again, you should see a green box in the website like so
