Involved Projects and Packages
Development project for the latest Chef version. In our approach to make Chef a part of openSUSE, the development of the Chef 11 core packages now happens mostly in the appropriate project, devel:languages:erlang.
Chef is an open source systems integration framework built to bring the benefits of configuration management to your entire infrastructure. You write source code to describe how you want each part of your infrastructure to be built, then apply those descriptions to your servers. The result is a fully automated infrastructure: when a new server comes on line, the only thing you have to do is tell Chef what role it should play in your architecture.

Jetporch - the Jet Enterprise Professional Orchestrator
Jetporch (aka Jet) is a general-purpose, community-driven IT automation platform for configuration management, deployment, orchestration, patching, and arbitrary task execution workflows.
Created and run by the creator of Ansible.
Packages related to opentofu, the open source fork of terraform
Fork of Terraform
OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu can manage existing and popular service providers as well as custom in-house solutions.
The key features of OpenTofu are:
- Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
- Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.
- Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
- Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
Packaging terraform and different external providers
Terragrunt is a thin wrapper for Terraform that provides extra tools for working with multiple Terraform modules.
What's this for?
When you need to see the output from all changed files within a directory.
Why doesn't tail -f /var/logs/* work?
Unfortunately, tail -f /logs/* may not do what you want it to do. Bash will expand * to all existing files within /logs/ and then show the extra lines added to each of them.
It also will not recurse down, any levels deeper than the current directory.
How is fstail different then?
fstail uses the gopkg.in/fsnotify to detect both new files, and existing files that are changed. It then starts concatenting their contents to the terminal.
I needed this for actuated.dev which launches microVMs on servers for CI.
Each VM launched will create a different file at: /var/log/actuated/GUID.txt, and tail -f * would only find existing files.
