Description Chris Janiszewski 2023-06-27 19:02:01 UTC

Description of problem:
Red Hat OpenStack Platform 17.0 and 17.1 is based on upstream Wallaby OpenStack version that comes with a new ability to boot Ironic nodes from ISO -> https://docs.openstack.org/ironic/latest/admin/ramdisk-boot.html#:~:text=Booting%20a%20Ramdisk%20or%20an%20ISO%C2%B6,contents%20being%20those%20in%20memory.

This issue is for Red Hat to validate, document and officially support this functionality with Red Hat OpenStack Platform 17+

The feature is being requested by Red Hat Customers to accommodate ISO based OpenShift installation methods .. aka Assisted Installer and Agent Based Installer, but other use cases of provisioning from ISO are also available.


Version-Release number of selected component (if applicable):
OSP17.1+

Additional info:
I was able to validate this use case in the POC lab on RH OSP17.0.1.  I was able to validate the installation of SNO OCP 4.13 on RHOSP17.0.1 Ironic via the ISO/ramdisk functionality.

There is also a related Jira request for shift-on-stack to validate, document and support this use case from the OpenShift perspective:
https://issues.redhat.com/browse/OCPSTRAT-119

Comment 1 James E. LaBarre 2023-07-25 18:29:15 UTC

Developing this testcase for z1

Comment 3 James E. LaBarre 2023-12-05 14:19:42 UTC

No updates on this currently

Comment 4 James E. LaBarre 2023-12-05 23:18:41 UTC

The Tempest, Infrared, etc changes probably need some updates (looks as though there aren't many if any recent changes in the affected files)

Also need to check my access for redhat-openstack/infrared, I don't see my change there.

otherwise I have https://code.engineering.redhat.com/gerrit/c/rhos-infrared/+/445878 and https://code.engineering.redhat.com/gerrit/c/rhos-qe-jenkins/+/445879

Reviewed with team, approved doc changes.

Comment 23 James E. LaBarre 2024-06-04 14:14:19 UTC

As Julia said, waiting on documentation
