Add labels and selectors to all resources. If the label key already is present on the resource, the value will be overridden.

{{% pageinfo color="warning" %}} Selectors for resources such as Deployments and Services shouldn't be changed once the resource has been applied to a cluster.

Changing commonLabels to live resources could result in failures. {{% /pageinfo %}}
