Orchestration API

For details on how to use orchestration, see Using OpenStack Orchestration

The Orchestration Class

The orchestration high-level interface is available through the orchestration member of a Connection object. The orchestration member will only be added if the service is detected.

Stack Operations

class openstack.orchestration.v1._proxy.Proxy(session=None, task_manager=None, *args, **kwargs)
create_stack(preview=False, **attrs)

Create a new stack from attributes

Parameters:
  • preview (bool) – When True, returns an StackPreview object, otherwise an Stack object. Default: ``False``
  • attrs (dict) – Keyword arguments which will be used to create a Stack, comprised of the properties on the Stack class.
Returns:

The results of stack creation
Return type:

Stack
check_stack(stack)

Check a stack’s status

Since this is an asynchronous action, the only way to check the result is to track the stack’s status.

Parameters:stack – The value can be either the ID of a stack or an instance of Stack.
Returns:None
update_stack(stack, **attrs)

Update a stack

Parameters:
  • stack – The value can be the ID of a stack or a Stack instance.
  • **attrs (kwargs) – The attributes to update on the stack represented by value.
Returns:

The updated stack
Return type:

Stack
Raises:

ResourceNotFound when no resource can be found.
delete_stack(stack, ignore_missing=True)

Delete a stack

Parameters:
  • stack – The value can be either the ID of a stack or a Stack instance.
  • ignore_missing (bool) – When set to False ResourceNotFound will be raised when the stack does not exist. When set to True, no exception will be set when attempting to delete a nonexistent stack.
Returns:

None
find_stack(name_or_id, ignore_missing=True)

Find a single stack

Parameters:
  • name_or_id – The name or ID of a stack.
  • ignore_missing (bool) – When set to False ResourceNotFound will be raised when the resource does not exist. When set to True, None will be returned when attempting to find a nonexistent resource.
Returns:

One Stack or None
get_stack(stack)

Get a single stack

Parameters:stack – The value can be the ID of a stack or a Stack instance.
Returns:One Stack
Raises:ResourceNotFound when no resource can be found.
get_stack_environment(stack)

Get environment used by a stack

Parameters:stack – The value can be the ID of a stack or an instance of Stack
Returns:One object of                   StackEnvironment
Raises:ResourceNotFound when no resource can be found.
get_stack_files(stack)

Get files used by a stack

Parameters:stack – The value can be the ID of a stack or an instance of Stack
Returns:A dictionary containing the names and contents of all files used by the stack.
Raises:ResourceNotFound when the stack cannot be found.
get_stack_template(stack)

Get template used by a stack

Parameters:stack – The value can be the ID of a stack or an instance of Stack
Returns:One object of StackTemplate
Raises:ResourceNotFound when no resource can be found.
stacks(**query)

Return a generator of stacks

Parameters:**query (kwargs) – Optional query parameters to be sent to limit the resources being returned.
Returns:A generator of stack objects
Return type:Stack
validate_template(template, environment=None, template_url=None, ignore_errors=None)

Validates a template.

Parameters:
  • template – The stack template on which the validation is performed.
  • environment – A JSON environment for the stack, if provided.
  • template_url – A URI to the location containing the stack template for validation. This parameter is only required if the template parameter is None. This parameter is ignored if template is specified.
  • ignore_errors – A string containing comma separated error codes to ignore. Currently the only valid error code is ‘99001’.
Returns:

The result of template validation.
Raises:

InvalidRequest if neither template not template_url is provided.
Raises:

HttpException if the template fails the validation.
resources(stack, **query)

Return a generator of resources

Parameters:
  • stack – This can be a stack object, or the name of a stack for which the resources are to be listed.
  • **query (kwargs) – Optional query parameters to be sent to limit the resources being returned.
Returns:

A generator of resource objects if the stack exists and there are resources in it. If the stack cannot be found, an exception is thrown.
Return type:

A generator of Resource
Raises:

ResourceNotFound when the stack cannot be found.

Software Configuration Operations

class openstack.orchestration.v1._proxy.Proxy(session=None, task_manager=None, *args, **kwargs)
create_software_config(**attrs)

Create a new software config from attributes

Parameters:attrs (dict) – Keyword arguments which will be used to create a SoftwareConfig, comprised of the properties on the SoftwareConfig class.
Returns:The results of software config creation
Return type:SoftwareConfig
delete_software_config(software_config, ignore_missing=True)

Delete a software config

Parameters:
  • software_config – The value can be either the ID of a software config or an instance of SoftwareConfig
  • ignore_missing (bool) – When set to False ResourceNotFound will be raised when the software config does not exist. When set to True, no exception will be set when attempting to delete a nonexistent software config.
Returns:

None
get_software_config(software_config)

Get details about a specific software config.

Parameters:software_config – The value can be the ID of a software config or a instace of SoftwareConfig,
Returns:An object of type SoftwareConfig
software_configs(**query)
