wes-service 3.3

GA4GH Workflow Execution Service reference implementation

Workflow as a Service

This provides client and server implementations of the GA4GH Workflow Execution Service API for the Common Workflow Language.

It provides an Arvados backend. It also works with any cwl-runner that supports the CWL standard command line interface: http://www.commonwl.org/v1.0/CommandLineTool.html#Executing_CWL_documents_as_scripts

Installation:

pip install wes-service

Run a standalone server with default cwl-runner backend:

$ wes-server

Submit a workflow to run:

$ wes-client --host=localhost:8080 myworkflow.cwl myjob.json

List workflows:

$ wes-client --list

Get workflow status:

$ wes-client --get <workflow-id>

Get stderr log from workflow:

$ wes-client --log <workflow-id>
