"""
CA Certs
--------
**Summary:** add ca certificates

This module adds CA certificates to ``/etc/ca-certificates.conf`` and updates
the ssl cert cache using ``update-ca-certificates``. The default certificates
can be removed from the system with the configuration option
``remove-defaults``.

.. note::
    certificates must be specified using valid yaml. in order to specify a
    multiline certificate, the yaml multiline list syntax must be used

.. note::
    For Alpine Linux the "remove-defaults" functionality works if the
    ca-certificates package is installed but not if the
    ca-certificates-bundle package is installed.

**Internal name:** ``cc_ca_certs``

**Module frequency:** per instance

**Supported distros:** alpine, debian, ubuntu, rhel

**Config keys**::

ca-certs:
        remove-defaults: <true/false>
        trusted:
            - <single line cert>
            - |
              -----BEGIN CERTIFICATE-----
              YOUR-ORGS-TRUSTED-CA-CERT-HERE
              -----END CERTIFICATE-----
