I'm confused. Yeah, boot-iso seems to assume this 'boot_iso' path, however generate_discovery_iso has dest: "{{ http_store_path }}/data/iso/discovery.iso", which I think means that if the inventory ever has boot_iso set to anything different, nothing's going to work anyway. Is this correct? If so, why even have it?
In fact, the inventory-bm.j2, inventory-bm.j2, and inventory-ibmcloud-bm.j2 templates hardcode discovery.iso while inventory-sno.j2 and inventory-ibmcloud-sno.j2 don't define boot_iso at all.

SNO's need a specific iso file generated for each SNO, where as a MNO/BM clusters uses the same ISO file for every node. So you can think of the iso files as specific to the cluster. The SNO inventory files do define boot_iso, it's just a host var instead of a host group var applied to all hosts in a group.

Thanks! Yeah, I see it now: I missed it in that enormous line in the SNO template. 😆
But the boot_iso settings in the non-SNO cases still seem like "lies" as generate-discovery-iso will always create discovery.iso but if a BYOL inventory sets boot_iso to something else, the boot-iso role will try to use it and won't find it. Should this be an SNO-only setting, or should the generate roles be fixed to use the var for consistency?

Yea, we should fix the generate roles so they use the vars for consistency, though I would really appreciate folks not mucking with generated inventory vars without researching what that does. But users will always be users...

Indeed, mucking with generated inventory files should come with a red blinking danger warning. I think BYOL is the bigger concern here, because we either should use boot_iso consistently or document clearly that it must be the "mandatory default" 😆

@Noreen21 or @dbutenhof Any chance you can test this with SNOs in your environment so I can merge this? |
