# 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/certificate.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
# create: true
#
# 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.
