question: pods in a completed state count against available-resource-calculation? about multi-cluster-app-dispatcher

[asm582]

MCAD in its current state will dispatch the workloads if a completed job referenced by appwrapper is deleted by the user. MCAD does not know when an item inside an appwrapper completes and the impact of one item completion on the entire appwrapper.

We already have a WIP progress PR that enables MCAD to have rich state information. This will enable MCAD to have more insights into the completion status of item(s) expressed by users.

@MEllis-github did we try to answer your question?

To recap, in the current version, once the AppWrapper reaches a Running state, all associated resources will be counted against the cluster's available resources until the AppWrapper is deleted by the user, is that right?
With the WIP, it will be possible to leverage rich state information to ~loosen this behavior?

Yes

No, the design is to always clean up pods. with new states, users can express when an item inside appwrapper completes so that the MCAD controller can delete such objects

This is helpful, thanks!

No, the design is to always clean up pods. with new states, users can express when an item inside appwrapper completes so that the MCAD controller can delete such objects

So in the new WIP specification, the user will be able to define a completion condition, and then MCAD will automatically adjust its resource calculation when that condition is reached, whether or not the AppWrapper has been deleted? Or alternatively, an automated or manual auxiliary method of cleaning-up AppWrapped workloads will always be required, but a service or user can leverage the rich state information to do so?
