This mission showcases application configuration, using OpenShift configmaps. It demonstrates application and runtime configuration leveraging external configuration sources. Alongside the basic means to set up a configmap and use with a specific runtime, this booster also demonstrates how changes to the configuration can be applied to services already deployed in OpenShift.
Invoke the service to see the result.
Open ConfigMap editor in your terminal:
oc edit configmap <CONFIGMAP_NAME>
Replace the greeting.message
greeting.message: Bonjour %s from a ConfigMap!
And reload your application
oc rollout latest dc/<DEPLOYMENT_NAME>
