A system of Kubernetes controllers that intelligently schedules workloads across clusters.

Cozystack is a free PaaS platform and framework for building clouds.

With Cozystack, you can transform your bunch of servers into an intelligent system with a simple REST API for spawning Kubernetes clusters, Database-as-a-Service, virtual machines, load balancers, HTTP caching services, and other services with ease.

You can use Cozystack to build your own cloud or to provide a cost-effective development environments.

Containerd is a popular container runtime used in Kubernetes. It serves as the underlying engine responsible for managing low-level tasks, such as creating and managing container sandboxes, starting processes within those sandboxes, and handling image pulling. As Containerd plays a crucial role in the smooth operation of containerized applications, monitoring its performance and health becomes essential.

TL;DR — Iptables is very brain hurty (I hope this is understood as a warning for what the rest of this post will cover…)

If you work with persistent storage in Kubernetes, maybe you've seen articles about how to migrate from in-tree to CSI volumes, but aren't sure what all the fuss is about? Or perhaps you're trying to debug a stuck VolumeAttachment that won't unmount from a node, holding up your important StatefulSet rollout? A clear understanding of what the Container Storage Interface (or CSI for short) is and how it works will give you confidence when dealing with persistent data in Kubernetes, allowing you to answer these questions and more!

Among a certain tech set, Kubernetes has earned a reputation as an unnecessarily complicated time-sink that startups should avoid. Using Kubernetes with a small team is seen as a sign of over-engineering.

The DeepFlow open-source project aims to provide deep observability for complex cloud-native and AI applications. DeepFlow implemented Zero Code data collection with eBPF for metrics, distributed tracing, request logs and function profiling, and is further integrated with SmartEncoding to achieve Full Stack correlation and efficient access to all observability data. With DeepFlow, cloud-native and AI applications automatically gain deep observability, removing the heavy burden of developers continually instrumenting code and providing monitoring and diagnostic capabilities covering everything from code to infrastructure for DevOps/SRE teams.

Tofu Controller (previously known as Weave TF-Controller) is a controller for Flux to reconcile OpenTofu and Terraform resources in the GitOps way. With the power of Flux together with OpenTofu and Terraform, Tofu Controller allows you to GitOps-ify infrastructure, and application resources, in the Kubernetes and IAC universe, at your own pace.

Seabird is a Kubernetes IDE designed for the GNOME desktop. Explore and manage your clusters with a simple and intuitive interface. Equipped with essential features such as a terminal for executing commands, monitoring through logs and metrics, and a resource editor that conveniently places the API reference at your fingertips.

Comfortably monitor your Internet traffic

Limbo is a work-in-progress, in-process OLTP database management system, compatible with SQLite.

Greenmask is a powerful open-source utility that is designed for logical database backup dumping, obfuscation, and restoration. It offers extensive functionality for backup, anonymization, and data masking. Greenmask is written entirely in pure Go and includes ported PostgreSQL libraries, making it platform-independent. This tool is stateless and does not require any changes to your database schema. It is designed to be highly customizable and backward-compatible with existing PostgreSQL utilities.

dockerc - compile docker images to standalone portable binaries

There are many guides out there on how to write software. This blog post series is a guide to software delivery: that is, all the processes, tools, and techniques that are required to run and maintain software in production on an ongoing basis. In particular, this series is a guide to DevOps, one of the methodologies used today to make software delivery vastly more efficient.

osquery exposes an operating system as a high-performance relational database. This allows you to write SQL-based queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.
