elasticluster.conf¶
-
class
elasticluster.conf.
ConfigReader
(configfile)[source]¶ Reads the configuration properties from a ini file.
Parameters: configfile (str) – path to configfile -
read_config
()[source]¶ Reads the configuration properties from the ini file and links the section to comply with the cluster config dictionary format.
Returns: dictionary containing all configuration properties from the ini file in compliance to the cluster config format Raises: voluptuous.MultipleInvalid
if not all sections present or broken links between secitons
-
-
class
elasticluster.conf.
ConfigValidator
(config)[source]¶ Validator for the cluster configuration dictionary.
Parameters: config – dictionary containing cluster configuration properties
-
class
elasticluster.conf.
Configurator
(cluster_conf, storage_path=None)[source]¶ - The Configurator is responsible for (I) keeping track of the
configuration and (II) offer factory methods to create all kind of objects that need information from the configuration.
The cluster configuration dictionary is structured in the following way: (see an example @
{ "<cluster_template>" : { "setup" : { properties of the setup section }, "cloud" : { properties of the cloud section }, "login" : { properties of the login section }, "cluster" : { properties of the cluster section }, "nodes": { "<node_kind>" : { properties of the node}, "<node_kind>" : { properties of the node}, }, }, "<cluster_template>" : { (see above) } }
Parameters: - cluster_conf (dict) – see description above
- storage_path (str) – path to store data
Raises: MultipleInvalid – configuration validation
-
create_cloud_provider
(cluster_template)[source]¶ Creates a cloud provider by inspecting the configuration properties of the given cluster template.
Parameters: cluster_template (str) – template to use (if not already specified on init) Returns: cloud provider that fulfills the contract of elasticluster.providers.AbstractSetupProvider
-
create_cluster
(template, name=None)[source]¶ Creates a cluster by inspecting the configuration properties of the given cluster template.
Parameters: - template (str) – name of the cluster template
- name (str) – name of the cluster. If not defined, the cluster
will be named after the template.
Returns: elasticluster.cluster.cluster
instanceRaises: ConfigurationError – cluster template not found in config
-
create_setup_provider
(cluster_template, name=None)[source]¶ Creates the setup provider for the given cluster template.
Parameters: - cluster_template (str) – template of the cluster
- name (str) – name of the cluster to read configuration properties
-
classmethod
fromConfig
(configfile, storage_path=None)[source]¶ Helper method to initialize Configurator from an ini file.
Parameters: configfile (str) – path to the ini file Returns: Configurator
