Description Ulrich Schlueter 2021-05-03 16:36:43 UTC
Description of problem:

The decision whether the InfraEnv resource for a clusterdeployment creates a minimal-iso or a full-iso version of the boot ISO for the cluster servers is currently made a Community Operator build time (by defining the subscription file) or latest at installation time (by modifying the subscription file ahead of a manual installation ). After encountering a problem with booting from minimal-iso for Dell hardware (https://bugzilla.redhat.com/show_bug.cgi?id=1955747 ) this turns out to be difficult to handle and not feasible for  the  multi-cluster/multi-customer setup we are looking for for OSD Baremetal 


Version-Release number of selected component (if applicable):


How reproducible:

Install the Community Edition Assisted Service from the OperatorHub and try to change the ISO format 

Steps to Reproduce:
1.
2.
3.

Actual results:

Format handled on Assisted Service instance level (install time setting)

Expected results:

Iso file format should be a parameter at clusterdeployment or InfraEnv creation time

@atraeger@redhat.com Is supporting only minimal-iso by default is a requirement? 
Do we want to make it part of the API with a default value to minimal-iso?

Comment 2 Avishay Traeger 2021-05-10 06:36:55 UTC
Ulrich, can you please elaborate on why this makes your use case difficult/unfeasible?  Our reasoning was that it was logical for a given deployment to want to use either the full or the minimal ISO, not both, and therefore we wanted to simplify the user-facing API.

Comment 3 Ulrich Schlueter 2021-05-14 14:34:30 UTC
Two points:
- this BZ is a knock-on effect of https://bugzilla.redhat.com/show_bug.cgi?id=1955747 where booting from the minimum-iso failed, but booting from the full-iso worked. Meanwhile that BZ is at least explained as a server side bug and worked around so this change is not required at the moment.

- The idea is not to have both formats at the same time, but making the iso format configurable without reinstalling the assisted-service operator. This would have appeared to be a useful feature in a scenario where many clusters are installed from the same operator instance (which is what I'm testing).
