Story #19132
Updated by Ward Vandewege over 2 years ago
Support versioning for registered workflows in Workbench.
Possible features:
* When launching a workflow, user can choose among multiple versions
* Can easily determine which version of the workflow was used to run a particular pipeline.
* Text of workflow that is used for execution is more like the text that the user started from (instead of workflow packing).
* Text of workflow as submitted (i.e. original) is also saved so that users can compare the "original" they submitted against their VCS later (good for auditability).
Possible design:
* Use collection versioning
* Store workflow metadata in properties
** entry point
** input spec
** git commit/branch/repo? if uploaded a git directory
** docker jobs image to use
* Are "workflow" records even needed any more? Could be kept in a collection with "type: workflow" property
* Identify the workflow version used for a given pipeline by matching the PDH
Implementation:
* arvados-cwl-runner support for creating/updating new-style registered workflows
* Workbench 2 support (this is probably the majority of the work)
