Vai: a Kubernetes API accelerator/cache
Make it faster!
There are use cases that put the Kubernetes API under heavy load - using Rancher at scale can be one of them.
Also, there are use cases in which a connection to the Kubernetes API might not always be present, or with good bandwidth - using Rancher for edge use cases can be one of them.
This project aims to create a local cache serving data from the Kubernetes API - with good performance and displaying last-good-results on a flaky connection.
Goal for this Hackweek
Implement Proof-Of-Concept client-go components backed by SQLite.

terraform-provider-feilong by e_bischoff
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.
