Description

Add support for scale several scaling group in one transaction.

Supported workflows

The plugin supports:

scaleuplist workflow

Create new instances with properties defined in scalable_entity_properties list.

Parameters:

scalable_entity_properties: List properties for nodes.
scale_compute: If a node name is passed as the scalable_entity_name parameter and that node is contained (transitively) within a compute node and this property is true, operate on the compute node instead of the specified node. Default: false
ignore_failure: Ignore failure on install. Default: false
ignore_rollback_failure: Ignore failure on rollback. Default: true
scale_transaction_field: Place to save transaction id created in same transaction. Default: _transaction_id
scale_transaction_value: Optional, transaction value.
node_sequence: Optional, sequence of nodes for run for override relationships.

scaledownlist workflow

Remove all instances from same transaction/property as node selected by scale_node_name. If instances can’t be deleted in one transaction - as result of workflow will be uninstalled instances with “uninitialized” status and runtime properties cleaned up, you should ignore such instances in future uninstall actions.

Parameters:

scale_compute: If a node name is passed as the scale_node_name parameter and that node is contained (transitively) within a compute node and this property is true, operate on the compute node instead of the specified node. Default: false
ignore_failure: Default: false
scale_transaction_field: Place to save transaction id created in same transaction. Optional, can be skipped if we need to remove instance without relation to initial transaction.
scale_node_name: A list of node ids. The operation will be executed only on node instances which are instances of these nodes. An empty list means no filtering will take place and all nodes are valid (Default: “").
scale_node_field: Node runtime properties field name for search value, supported search by ['a', 'b'] on {'a': {'b': 'c'}} return c.
scale_node_field_value: Node runtime properties field value for search. Can be provided as list of possible values.
force_db_cleanup: Run DB cleanup directly if instances can’t be deleted in one transaction.
all_results: Get all instances for filter. Required 4.4+ manager. Default: false
node_sequence: Optional, sequence of nodes for run for override relationships.

update_operation_filtered workflow

Execute action on selected nodes.

Parameters:

operation: The name of the operation to execute. (Default: cloudify.interfaces.lifecycle.update).
operation_kwargs: A dictionary of keyword arguments that will be passed to the operation invocation (Default: {}).
allow_kwargs_override: A boolean describing whether overriding operations inputs defined in the blueprint by using inputs of the same name in the operation_kwargs parameter is allowed or not (Default: null, means that the default behavior, as defined by the workflows infrastructure, will be used).
run_by_dependency_order: A boolean describing whether the operation should execute on the relevant nodes according to the order of their relationships dependencies or rather execute on all relevant nodes in parallel. (Default: false).
type_names: A list of type names. The operation will be executed only on node instances which are of these types or of types which (recursively) derive from them. An empty list means no filtering will take place and all type names are valid (Default: []).
node_ids: A list of node ids. The operation will be executed only on node instances which are instances of these nodes. An empty list means no filtering will take place and all nodes are valid (Default: []).
node_instance_ids: A list of node instance ids. The operation will be executed only on the node instances specified. An empty list means no filtering will take place and all node instances are valid. (Default: []).
node_field: Node runtime properties field name for search value, supported search by ['a', 'b'] on {'a': {'b': 'c'}} return c.
node_field_value: Node runtime properties field value for search. Can be provided as list of possible values.

Examples

Example for show scaling several scaling group within one transaction.

Install with one “two” node

We install blueprint with one “two” nodes.
