+# This is a template for requesting a certificate from the cert-manager (https://cert-manager.io).
+#
+# To request a certificate following steps are to be done:
+#  - create an object 'certificates' in the values.yaml
+#  - create a file templates/certificates.yaml and invoke the function "certManagerCertificate.certificate".
+#
+# Here is an example of the certificate request for a component:
+#
+# Directory structure:
+#   component
+#     templates
+#       certifictes.yaml
+#     values.yaml
+#
+# To be added in the file certificates.yamll
+#
+# To be added in the file values.yaml
+#  1. Minimal version (certificates only in PEM format)
+#  certificates:
+#    - commonName: component.onap.org
+#
+#  2. Extended version (with defined own issuer and additional certificate format):
+#  certificates:
+#    - name:       onap-component-certificate
+#      secretName: onap-component-certificate
+#      commonName: component.onap.org
+#      dnsNames:
+#        - component.onap.org
+#      issuer:
+#        group: certmanager.onap.org
+#        kind: CMPv2Issuer
+#        name: cmpv2-issuer-for-the-component
+#      keystore:
+#        outputType:
+#          - p12
+#          - jks
+#        passwordSecretRef:
+#          name: secret-name
+#          key:  secret-key
+#
+# Fields 'name', 'secretName' and 'commonName' are mandatory and required to be defined.
+# Other mandatory fields for the certificate definition do not have to be defined directly,
+# in that case they will be taken from default values.
+#
+# Default values are defined in file onap/values.yaml (see-> global.certificate.default)
+# and can be overriden during onap installation process.
