Dear ONAP friends,
as you might know we are working on offline-installer solution for ONAP, our first platform was RHEL 7.4. Now we have reached some limitations of this platform and starting with Casablanca old RHEL7.4 kernel is crashing (attached) We are considering adding support for some Centos distribution, later-on it might be ubuntu/xenial but we are not sure what version to pick, is there any information regarding some recommended OS platform + version for Casablanca and later Dublin ONAP ??? Not sure if everyone is just on xenial as its reference rancher platform, for us some rpm distro would be easier to start with. https://onap.readthedocs.io/en/latest/submodules/oom.git/docs/oom_setup_kubernetes_rancher.html#onap-on-kubernetes-with-rancher “Select Ubuntu 16.04 as base image …“ any comment / feedback appreciated thanks, Michal -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
