Filip Brychta commented on SWSQE-1056:
--------------------------------------

{color:#333333}Currently the only tested/working way is a bare metal IPI on single stack IPv6, docs here [1]. I know about two teams which have a CI for that. Openshift-kni dev team is using [2] and ocp-edge-qe team is using [3]. Both approaches are mocking bare metal machines as VMs on one big hypervisor and using IPI way.{color}
{color:#333333}I tried [2] on our bare metal machine (b24.jonqe.lab.eng.bos.redhat.com) in BOS lab which has 64GB of memory and 32 CPUs which should match minimal resource requirements. The cluster was provisioned fine (after several tries) but any change which requires cluster reconciliation breaks it. Some cluster operators (authentication, dns, kube-storage-version-migrator, network, openshift-apiserver) are stuck in progressing state or degraded and the cluster never come back up. This is blocking SM installation as on IPv6 it's necessary to mirror SM operators from redhat-operators (the same way like in disconnected OCP) which is starting the cluster reconciliation.{color}
{color:#333333}I've not tried [3] yet as it requires machine with 144 GB of memory and I don't have such a big machine.{color}

{color:#333333}Possible next steps:{color}
{color:#333333}- try [2] on bigger machine as the minimal required resources might not be enough (cluster with minimal resources seems pretty fragile even on IPv4), bigger machine might be available in http://bagl.scalelab.redhat.com/ or https://beaker.engineering.redhat.com/{color}
{color:#333333}- wait for working UPI installer and update our existing provisioning scripts for IPv6 (our scripts are mocking bare metal machines as VMs in PSI OpenStack and using UPI way){color}
{color:#333333}- wait for working templates for Flexy, e.g. [4] and use the One OCP deploy tool{color}
