+In order to use certServiceClient it is needed do define certificates array in target component values.yaml. Each
+certificate will be requested from separate init container
+
+Minimum example of array in target component values.yaml:
+certificates:
+ - mountPath: /var/custom-certs
+ commonName: common-name
+
+Full example (other fields are ignored):
+certificates:
+ - mountPath: /var/custom-certs
+ caName: RA
+ outputType: JKS
+ commonName: common-name
+ dnsNames:
+ - dns-name-1
+ - dns-name-2
+ ipAddresses:
+ - 192.168.0.1
+ - 192.168.0.2
+ emailAddresses:
+ - email-1@onap.org
+ - email-2@onap.org
+ uris:
+ - http://uri-1.onap.org
+ - http://uri-2.onap.org
+ subject:
+ organization: Linux-Foundation
+ country: US
+ locality: San Francisco
+ province: California
+ organizationalUnit: ONAP
+
+There also need to be some includes used in a target component deployment (indent values may need to be adjusted):
+ 1. In initContainers section:
+ {{ include "common.certServiceClient.initContainer" . | indent 6 }}
+ 2. In volumeMounts section of container using certificates:
+ {{ include "common.certServiceClient.volumeMounts" . | indent 10 }}
+ 3. In volumes section:
+ {{ include "common.certServiceClient.volumes" . | indent 8 }}
