Bug #14710
Updated by Peter Amstutz over 5 years ago
Child containers are determined by querying for container requests where requested_by_container_uuid matches the parent container. This does not work for federated workflows, because (a) containers run on remote clusters don't set @requested_by_container_uuid@ and (b) even if it was set, we don't have an easy way to query it (requires either #14374 or generalizing javascript multi-site search feature).
For (a) The arvados-cwl-runner does know which containers it is tracking. so it could explicitly update the container record with a list of child containers, similar to the runtime_status feature.
