This initial implementation supports ConfigMaps only, as this is the only
external volume mounting required by current microservices.
-.Values.externalValues is a list of objects. Each object has 3 required fields and 1 optional field:
+.Values.externalVolumes is a list of objects. Each object has 3 required fields and 2 optional fields:
- name: the name of the resource (in the current implementation, it must be a ConfigMap)
that is to be set up as a volume. The value is a case sensitive string. Because the
names of resources are sometimes set at deployment time (for instance, to prefix the Helm
value is a case-sensitive string.
- readOnly: (Optional) Boolean flag. Set to true to mount the volume as read-only.
Defaults to false.
+ - optional: (Optional) Boolean flag. Set to true to make the configMap optional (i.e., to allow the
+ microservice's pod to start even if the configMap doesn't exist). If set to false, the configMap must
+ be present in order for the microservice's pod to start. Defaults to true. (Note that this
+ default is the opposite of the Kubernetes default. We've done this to be consistent with the behavior
+ of the DCAE Cloudify plugin for Kubernetes [k8splugin], which always set "optional" to true.)
Here is an example fragment from a values.yaml file for a microservice:
