Pipeline API: Do I have to always specify all the nodes and edges?

The default PipelineCreate API call requires you to define the full nodes/edges structure, and allows you to override items.

There's another API that allows you to say "Run this pipeline from this commit with the default values from valohai.yaml": PipelineCreateFromTemplate.

• Send a POST request to: https://app.valohai.com/api/v0/pipelines/create-from-template/
• Include the following things in the request body: project id, commit, and the name of the pipeline as written in your valohai.yaml.
  • Instead of specifying the commit hash, you can also use the latest fetched commit from a branch by using the branch name (e.g. main ).

Note that the PipelineCreateFromTemplate does not allow any overrides. Moreover, you don't need to specify environment . Valohai will use the step default environments, or if the step doesn't have one, it'll use the project/org default environment.
