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" ping_url: "http://landscape.canonical.com/ping" data_path: "/var/lib/landscape/client" http_proxy: "http://my.proxy.com/foobar" https_proxy: "https://my.proxy.com/foobar" tags: "server,cloud" computer_title: "footitle" registration_key: "fookey" account_name: "fooaccount" """ import os from six import BytesIO from configobj import ConfigObj from cloudinit import type_utils from cloudinit import util from cloudinit.settings import PER_INSTANCE frequency = PER_INSTANCE LSC_CLIENT_CFG_FILE = "/etc/landscape/client.conf" LS_DEFAULT_FILE = "/etc/default/landscape-client" distros = ['ubuntu'] # defaults taken from stock client.conf in landscape-client 11.07.1.1-0ubuntu2 LSC_BUILTIN_CFG = { 'client': { 'log_level': "info", 'url': "https://landscape.canonical.com/message-system", 'ping_url': "http://landscape.canonical.com/ping", 'data_path': "/var/lib/landscape/client", } } def handle(_name, cfg, cloud, log, _args): """ Basically turn a top level 'landscape' entry with a 'client' dict and render it to ConfigObj format under '[client]' section in /etc/landscape/client.conf """ ls_cloudcfg = cfg.get("landscape", {}) if not isinstance(ls_cloudcfg, (dict)): raise RuntimeError( "'landscape' key existed in config, but not a dictionary type," " is a {_type} instead".format( _type=type_utils.obj_name(ls_cloudcfg))) if not ls_cloudcfg: return cloud.distro.install_packages(('landscape-client',)) merge_data = [ LSC_BUILTIN_CFG, LSC_CLIENT_CFG_FILE, ls_cloudcfg, ] merged = merge_together(merge_data) contents = BytesIO() merged.write(contents) util.ensure_dir(os.path.dirname(LSC_CLIENT_CFG_FILE)) util.write_file(LSC_CLIENT_CFG_FILE, contents.getvalue()) log.debug("Wrote landscape config file to %s", LSC_CLIENT_CFG_FILE) util.write_file(LS_DEFAULT_FILE, "RUN=1\n") util.subp(["service", "landscape-client", "restart"]) def merge_together(objs): """ merge together ConfigObj objects or things that ConfigObj() will take in later entries override earlier """ cfg = ConfigObj({}) for obj in objs: if not obj: continue if isinstance(obj, ConfigObj): cfg.merge(obj) else: cfg.merge(ConfigObj(obj)) return cfg # vi: ts=4 expandtab Submit
