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, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)
create_stack(preview=False, **attrs)

Create a new stack from attributes

Parameters

  • preview (bool) – When True, a preview endpoint will be used to verify the template 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, preview=False, **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, resolve_outputs=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, resolve_outputs=True)

Get a single stack

Parameters

  • stack – The value can be the ID of a stack or a Stack instance.

  • resolve_outputs – Whether stack should contain outputs resolved.

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.
