+dcaegen2-services-common._externalVolumes:
+This template generates a list of volumes associated with the pod,
+based on information provided in .Values.externalVolumes. This
+template works in conjunction with dcaegen2-services-common._externalVolumeMounts
+to give the microservice access to data in volumes created else.
+This initial implementation supports ConfigMaps only, as this is the only
+external volume mounting required by current microservices.
+
+.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
+ release to the name), the string can be a Helm template fragment that will be expanded at
+ deployment time.
+ - type: the type of the resource (in the current implementation, only "ConfigMap" is supported).
+ The value is a case-INsensitive string.
+ - mountPoint: the path to the mount point for the volume in the container file system. The
+ 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:
+
+externalVolumes:
+ - name: my-example-configmap
+ type: configmap
+ mountPath: /opt/app/config
+ - name: '{{ include "common.release" . }}-another-example'
+ type: configmap
+ mountPath: /opt/app/otherconfig
+ optional: false
