Landscape
---------
**Summary:** install and configure landscape client
This module installs and configures ``landscape-client``. The landscape client
will only be installed if the key ``landscape`` is present in config. Landscape
client configuration is given under the ``client`` key under the main
``landscape`` config key. The config parameters are not interpreted by
cloud-init, but rather are converted into a ConfigObj formatted file and
written out to ``/etc/landscape/client.conf``.
The following default client config is provided, but can be overridden::
landscape:
client:
log_level: "info"
url: "https://landscape.canonical.com/message-system"
ping_url: "http://landscape.canoncial.com/ping"
data_path: "/var/lib/landscape/client"
.. note::
see landscape documentation for client config keys
.. note::
if ``tags`` is defined, its contents should be a string delimited with
``,`` rather than a list
**Internal name:** ``cc_landscape``
**Module frequency:** per instance
**Supported distros:** ubuntu
**Config keys**::
landscape:
client:
url: "https://landscape.canonical.com/message-system"
