CRUD

The CRUD methods are used to create, read, update and delete workflows. There are two ways to use them. The first is through the SDK and the second is through the Project object. The syntax is the same for all CRUD methods. If you want to manage workflows from the project, you can use the Project object and avoid to specify the project parameter. In this last case, you need to specify every parameter as keyword argument.

A workflow entity can be managed with the following methods.

Create:

Read:

Update:

Delete:

Create

You can create a workflow with the new_workflow(). The kwargs parameters are determined by the kind of the object, and are described in the kinds section.

New

This function create a new entity and saves it into the backend.

new_workflow

None
description str

>>>                    name="my-function",
>>>                    kind="kfp",
>>>                    code_src="pipeline.py",
>>>                    handler="pipeline-handler")

Read

To read workflows you can use the get_workflow(), get_workflow_versions(), list_workflows() or import_workflow() workflows.

Get

This function searches for a single workflow into the backend. If you want to collect a workflow from the backend using get_workflow(), you have two options:

  • The first one is to use the key parameter which has the pattern store://<project-name>/<entity-type>/<entity-kind>/<entity-name>:<entity-id>.
  • The second one is to use the entity name as identifier, the project name as project and the entity id as entity_id parameters. If you do not specify the entity id, you will get the latest version.
get_workflow

Parameters:

Name Type Description Default
identifier str

Entity key (store://...) or entity name.

required
project str

Project name.

None
entity_id str

Entity ID.

None
**kwargs dict

{}

Returns:

Type Description
Workflow

>>> obj = get_workflow("store://my-workflow-key")

Using entity name:

>>> obj = get_workflow("my-workflow-name"
>>>                    project="my-project",
>>>                    entity_id="my-workflow-id")

Get versions

This function returns all the versions of a workflow from the backend.
