Project Description
People need to test operating systems and applications on s390 platform.
Installation from scratch solutions include:
- just deploy and provision manually
(with the help of ftpbootscript, if you are at SUSE) - use
s3270terminal emulation (used byopenQApeople?) - use
LXCfrom IBM to start CP commands and analyze the results - use
zPXEto do some PXE-alike booting (used by theorthosteam?) - use
tessiato install from scratch using autoyast - use
libvirtfor s390 to do some nested virtualization on some already deployed z/VM system - directly install a Linux kernel on a LPAR and use
kvm+libvirtfrom there
Deployment from image solutions include:
- use
ICICweb interface (openstackin disguise, contributed by IBM) - use
ICICfrom theopenstackterraformprovider (used byRancherQA) - use
zvm_ansibleto controlSMAPI - connect directly to
SMAPIlow-level socket interface
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.
Other Feilong-based solutions include:
- make
libvirtFeilong-aware - simply call
Feilongfrom shell scripts withcurl - use
zvmconnectorclient python library from Feilong - use
zthinpart of Feilong to directly commandSMAPI.
Goal for Hackweek 23
My final 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.
My technical 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, and compatible with our existing development infrastructure.
Goals for Hackweek 24
Feilong provider works and is used internally by SUSE Manager team. Let's push it forward!
Let's add support for fiberchannel disks and multipath.
Possible goals for Hackweek 25
Modernization, maturity, and maintenance.
- in Feilong itself: . add support for SLES 16, and Network Manager in general
- in the Go library: . add calls for the new functions that appeared in upstream Feilong . move from private repos to Open Mainframe project
- in the terraform provider: . finish support for fiberchannel disks and multipath . fix problems with registration on hashicorp providers registry . finish the U part of CRUD . move from private repos to Open Mainframe project

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
terraformas we need to support both plugin protocols 5 and 6.The good part is that we get a golang library for
Feilongfor 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.

Go library has now 100% coverage.
I'm not sure anymore that the protocol 5 provider was useful, but I'll keep maintaining it because it's handy for my tests.
The provider still lacks R and U parts of CRUD.

In Feilong source code, some functions are undocumented, mainly around FiberChannel. This means that the Go library is not 100% complete as I thought. I will try to add the missing Go methods as well as the documentation in Feilong itself.

I have added all missing functions to the Go library. I also wrote the upstream API doc for all missing functions and tried to fix as much as I could the rest of the upstream API doc. That was around one thousand modified documentation lines.
Using these new functions, and with the help of Mike, I was able to make both FiberChannel and multipath work. We still need ad hoc images though, with multipath-tools package installed and multipathd service enabled. I'll try to get them either from Mike or from the public cloud team.

The hackweek 24 is getting to its end. I prepared a kind of TODO for hackweek 25, with remaining issues.

Mammuthus - The NFS-Ganesha inside Kubernetes controller by vcheng
Description
As the user-space NFS provider, the NFS-Ganesha is wieldy use with serval projects. e.g. Longhorn/Rook. We want to create the Kubernetes Controller to make configuring NFS-Ganesha easy. This controller will let users configure NFS-Ganesha through different backends like VFS/CephFS.
Goals
- Create NFS-Ganesha Package on OBS: nfs-ganesha5, nfs-ganesha6
- Create NFS-Ganesha Container Image on OBS: Image
- Create a Kubernetes controller for NFS-Ganesha and support the VFS configuration on demand. Mammuthus
