outerbounds

✓ from metaflow_extensions import outerbounds

✗ from ob_metaflow_extensions.decorators import outerbounds

This quickstart demonstrates a basic Metaflow flow using the `@outerbounds` decorator, which enables deployment to the Outerbounds Platform. It requires Metaflow to be installed and Outerbounds authentication configured (e.g., via `OUTERBOUNDS_TOKEN` environment variable or Outerbounds CLI login).

from metaflow import FlowSpec, step from ob_metaflow_extensions.decorators import outerbounds # Ensure OUTERBOUNDS_TOKEN environment variable is set for deployment # or ensure you are logged in via Outerbounds CLI @outerbounds class MyOuterboundsFlow(FlowSpec): """ A simple Metaflow flow deployable to the Outerbounds Platform. """ @step def start(self): print("Starting MyOuterboundsFlow") self.message = "Hello from Outerbounds!" self.next(self.end) @step def end(self): print(f"MyOuterboundsFlow finished! Message: {self.message}") if __name__ == '__main__': # To run locally: # python your_flow_file.py run # To deploy to Outerbounds (requires CLI login or token): # python your_flow_file.py deploy MyOuterboundsFlow()

Known issues

gotchaVersion compatibility with `metaflow` is crucial. `ob-metaflow-extensions` is built against specific Metaflow versions. Mismatches can lead to runtime errors or unexpected behavior.

fix

Always check the `ob-metaflow-extensions` documentation or release notes for compatible `metaflow` versions. Upgrade both packages in tandem if necessary.

affects: All versions

gotchaDeploying or running flows on the Outerbounds Platform requires proper authentication. This typically involves setting the `OUTERBOUNDS_TOKEN` environment variable or logging in via the Outerbounds CLI (`ob login`).

fix

Ensure `OUTERBOUNDS_TOKEN` is correctly set in your environment, or run `ob login` to authenticate your CLI session before deploying or interacting with platform features.

affects: All versions

gotchaPlatform-specific features (e.g., S3 artifact storage, Kubernetes orchestration) often require additional environment variables or cluster-side configurations. Errors related to permissions or resource access are common.

fix

Consult Outerbounds Platform documentation for required environment variables (e.g., `AWS_REGION`, `OUTERBOUNDS_NAMESPACE`) and ensure your Outerbounds workspace has the necessary permissions configured for the actions your flow performs.
