Bridle - Terraform remote backend in Kubernetes
a project by nroberts
Updated over 3 years ago. 3 hacker ♥️. 9 followers.

Project Description

Terraform's remote backend requires a Terraform Cloud account and has an initial limited offering. While the initial offering is suitable for small resource management and teams this quickly becomes an issue as usage demands increase. In addition Terraform's remote operations (plan,apply, etc) are executed on HashiCorp's cloud resources which present issues for sensitive data such as passwords and access keys. Users are also constrained to as what tooling is available on the remote execution environment for example having kubectl as part of a local-resource. This project aims to address these shortcomings in a native Kubernetes implementation.

Goal for this Hackweek

  • Have remote plan and apply operations execution handled in Kubernetes
  • State management: locking and storage
  • Logging: execution output (plan and apply)
  • User interface: view execution output and approve apply operations
  • Helm chart for deploying project

Stretch Goals

  • Trigger plan on Github PR

Implementation

We hope to take the rancher terraform-controller and add a REST API to it to speak Terraform Cloud (sometimes called tfe or terraform enterprise in their docs). We should be able to deploy the controller and write HCL with a backend remote hostname to this new API and run terraform plan/apply from your desktop and use resources in your k8s cluster.

    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 add-emoji (with the help of ftpboot script, if you are at SUSE)
    • use s3270 terminal emulation (used by openQA people?)
    • use LXC from IBM to start CP commands and analyze the results
    • use zPXE to do some PXE-alike booting (used by the orthos team?)
    • use tessia to install from scratch using autoyast
    • use libvirt for s390 to do some nested virtualization on some already deployed z/VM system
    • directly install a Linux kernel on a LPAR and use kvm + libvirt from there

    Deployment from image solutions include:

    • use ICIC web interface (openstack in disguise, contributed by IBM)
    • use ICIC from the openstack terraform provider (used by Rancher QA)
    • use zvm_ansible to control SMAPI
    • connect directly to SMAPI low-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 libvirt Feilong-aware
    • simply call Feilong from shell scripts with curl
    • use zvmconnector client python library from Feilong
    • use zthin part of Feilong to directly command SMAPI.

    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.

    Rancher/k8s Trouble-Maker by tonyhansen

    Project Description

    When studying for my RHCSA, I found trouble-maker, which is a program that breaks a Linux OS and requires you to fix it. I want to create something similar for Rancher/k8s that can allow for troubleshooting an unknown environment.

    Goals for Hackweek 25

    • Update to modern Rancher and verify that existing tests still work
    • Change testing logic to populate secrets instead of requiring a secondary script
    • Add new tests

    Goals for Hackweek 24 (Complete)

    • Create a basic framework for creating Rancher/k8s cluster lab environments as needed for the Break/Fix
    • Create at least 5 modules that can be applied to the cluster and require troubleshooting

    Cluster API Provider for Harvester by rcase

    Project Description

    The Cluster API "infrastructure provider" for Harvester, also named CAPHV, makes it possible to use Harvester with Cluster API. This enables people and organisations to create Kubernetes clusters running on VMs created by Harvester using a declarative spec.

    The project has been bootstrapped in HackWeek 23, and its code is available here.

    Work done in HackWeek 2023

    • Have a early working version of the provider available on Rancher Sandbox : *DONE *
    • Demonstrated the created cluster can be imported using Rancher Turtles: DONE
    • Stretch goal - demonstrate using the new provider with CAPRKE2: DONE and the templates are available on the repo

    DONE in HackWeek 24:

    DONE in 2025 (out of Hackweek)

    • Support of ClusterClass
    • Add to clusterctl community providers, you can add it directly with clusterctl
    • Testing on newer versions of Harvester v1.4.X and v1.5.X
    • Support for clusterctl generate cluster ...
    • Improve Status Conditions to reflect current state of Infrastructure
    • Improve CI (some bugs for release creation)

    Goals for HackWeek 2025

    • FIRST and FOREMOST, any topic is important to you
    • Add e2e testing
    • Certify the provider for Rancher Turtles
    • Add Machine pool labeling
    • Add PCI-e passthrough capabilities.
    • Other improvement suggestions are welcome!

    Thanks to @isim and Dominic Giebert for their contributions!

    A CLI for Harvester by mohamed.belgaied

    [comment]: # Harvester does not officially come with a CLI tool, the user is supposed to interact with Harvester mostly through the UI [comment]: # Though it is theoretically possible to use kubectl to interact with Harvester, the manipulation of Kubevirt YAML objects is absolutely not user friendly. [comment]: # Inspired by tools like multipass from Canonical to easily and rapidly create one of multiple VMs, I began the development of Harvester CLI. Currently, it works but Harvester CLI needs some love to be up-to-date with Harvester v1.0.2 and needs some bug fixes and improvements as well.

    Project Description

    Harvester CLI is a command line interface tool written in Go, designed to simplify interfacing with a Harvester cluster as a user. It is especially useful for testing purposes as you can easily and rapidly create VMs in Harvester by providing a simple command such as: harvester vm create my-vm --count 5 to create 5 VMs named my-vm-01 to my-vm-05.

    asciicast

    Harvester CLI is functional but needs a number of improvements: up-to-date functionality with Harvester v1.0.2 (some minor issues right now), modifying the default behaviour to create an opensuse VM instead of an ubuntu VM, solve some bugs, etc.

    Github Repo for Harvester CLI: https://github.com/belgaied2/harvester-cli

    Done in previous Hackweeks

    • Create a Github actions pipeline to automatically integrate Harvester CLI to Homebrew repositories: DONE
    • Automatically package Harvester CLI for OpenSUSE / Redhat RPMs or DEBs: DONE

    Goal for this Hackweek

    The goal for this Hackweek is to bring Harvester CLI up-to-speed with latest Harvester versions (v1.3.X and v1.4.X), and improve the code quality as well as implement some simple features and bug fixes.

    Some nice additions might be: * Improve handling of namespaced objects * Add features, such as network management or Load Balancer creation ? * Add more unit tests and, why not, e2e tests * Improve CI * Improve the overall code quality * Test the program and create issues for it

    Issue list is here: https://github.com/belgaied2/harvester-cli/issues

    Resources

    The project is written in Go, and using client-go the Kubernetes Go Client libraries to communicate with the Harvester API (which is Kubernetes in fact). Welcome contributions are:
