osia.installer.clouds package

Submodules

osia.installer.clouds.aws module

Module implements configuration object for aws installation

class osia.installer.clouds.aws.AWSInstaller(cluster_region=None, list_of_regions=None, **kwargs)

Bases: osia.installer.clouds.base.AbstractInstaller

Object containing all configuration related to aws installation

acquire_resources()

Method which is called before the install-config can be generated. The method should be used to get all necessary dependencies to fill in details in install-config

get_template_name()

Method to obtain name of jinja template related to specified platform.

post_installation()

Method called after the installation is done, this is the place where, things like registration of apps domain and other is expected to happen.

osia.installer.clouds.aws.get_free_region(order_list: List[str]) → Optional[str]

Finds first free region in provided list, if provided list is empty, it searches all regions

osia.installer.clouds.base module

Module implements common base for install-config creation. It also implements logic to obtain correct specification for specified installation platform

class osia.installer.clouds.base.AbstractInstaller(cluster_name=None, base_domain=None, master_flavor=None, master_replicas=None, pull_secret_file=None, ssh_key_file=None, worker_flavor=None, worker_replicas=None, certificate_bundle_file=None, cluster_directory=None, skip_clean=False, installer=None, **unused_kwargs)

Bases: abc.ABC

Base object for configuration of install-config

abstract acquire_resources()

Method which is called before the install-config can be generated. The method should be used to get all necessary dependencies to fill in details in install-config

check_clean()

Method returns if installation is configured to clean resources on failure.

classmethod get_environment() → jinja2.environment.Environment

Method loads jinja templates

abstract get_template_name()

Method to obtain name of jinja template related to specified platform.

abstract post_installation()

Method called after the installation is done, this is the place where, things like registration of apps domain and other is expected to happen.

process_template()

Method executes creation of install-config.yaml

class osia.installer.clouds.base.InstallerProvider

Bases: object

Class implements dynamic provider of registered platform specific implementations of AbstractInstaller. Class implements singleton design pattern.

add_installer(name: str, instance: ClassVar)

Insert concrete implementation of AbstractInstaller into the registry

classmethod instance() → osia.installer.clouds.base.InstallerProvider

Method to obtains singleton instance.

classmethod register(name, instance)

Method to dynamically register implementation of AbstractInstaller

osia.installer.clouds.openstack module

Module implements support for Openstack installation

exception osia.installer.clouds.openstack.ImageException(*args, **kwargs)

Bases: Exception

Image exception encapsulates Exception happening while image resolution

class osia.installer.clouds.openstack.OpenstackInstaller(osp_cloud=None, osp_base_flavor=None, network_list=None, os_image=None, images_dir=None, osp_image_download=False, osp_image_unique=False, args=None, **kwargs)

Bases: osia.installer.clouds.base.AbstractInstaller

Class containing configuration related to openstack

acquire_resources()

Method which is called before the install-config can be generated. The method should be used to get all necessary dependencies to fill in details in install-config

get_template_name()

Method to obtain name of jinja template related to specified platform.

post_installation()

Method called after the installation is done, this is the place where, things like registration of apps domain and other is expected to happen.

osia.installer.clouds.openstack.add_cluster(osp_connection: openstack.connection.Connection, image: openstack.image.v2.image.Image, cluster_name: str)

Function adds cluster name to image metadata in order to prevent image deletion

osia.installer.clouds.openstack.delete_fips(fips_file: str)

Deletes floating ips stored in configuration file

osia.installer.clouds.openstack.delete_image(fips_file, cluster_name)

Function checkes the uploaded image into openstack and removes from its metadata information about associated cluster. If last associated cluster was removed, the image is deleted

osia.installer.clouds.openstack.resolve_image(osp_connection: openstack.connection.Connection, cloud: str, cluster_name: str, images_dir: str, installer: str, error: Optional[Exception])

Function searches for image in openstack and creates it if it doesn’t exist

osia.installer.clouds.openstack.upload_uniq_image(osp_connection: openstack.connection.Connection, cloud: str, cluster_name: str, images_dir: str, installer: str)

Function uploads unique image to the cluster, instead of making shared one
