Project Description

People need to test operating systems and applications on s390 platform. Solutions include:

  • just deploy and provision manually add-emoji (with the help of ftpboot script, if you are at SUSE)
  • use s3270 terminal emulation (used by openQA people?)
  • use zPXE to do some PXE-alike booting (used by the orthos team?)
  • use ICIC web interface (openstack in disguise, contributed by IBM)
  • use ICIC from the openstack terraform provider (used by Rancher QA)
  • use tessia to install from scratch using autoyast
  • use libvirt for s390 to do some nested virtualization on some already deployed z/VM system
  • connect to SMAPI low-level socket interface
  • directly install a Linux kernel on a LPAR and use kvm + libvirt from there

IBM Cloud Infrastructure Center (ICIC) harnesses the Feilong API, but you can use Feilong without installing ICIC, provided you set up a "z/VM cloud connector" into one of your VMs following this schema.

What about writing a terraform Feilong provider, just like we have the terraform libvirt provider? That would allow to transparently call Feilong from your main.tf files to deploy and destroy resources on your system/z.

Goal for this Hackweek

My real goal is to be able to easily deploy and provision VMs automatically on a z/VM system, in a way that people might enjoy even outside of SUSE.

Other solutions include e.g. making libvirt Feilong-aware, or simply calling Feilong from shell scripts.

My preference is to write a terraform provider plugin, as it is the approach that involves the least software components for our deployments, while remaining clean.

      As the Feilong project chair, I like the terraform-feilong-provider project and making libvirt Feilong-aware. I will support your effort!

      Thanks for your support Mike. For the moment, I am still not completely sure whether I will take the terraform approach or the libvirt approach. The first one seems to me better, as for practical purposes it's one software layer less for us. I could even pick up something completely different. But so far the terraform provider approach seems the most promising for the least effort.

      OK, decision taken, I will stick to the terraform approach.

      The bad part is that I have to code for 2 versions of terraform as we need to support both plugin protocols 5 and 6.

      The good part is that we get a golang library for Feilong for free (there is a project ZVM connector golang but it does not provide marshalling and demarshalling).

      We have a working provider and a partial Go library. Mission accomplished, although it would be nice to attract other contributors and fill in the holes.
