Monitor cross-zone network traffic in Kubernetes.

K3k, Kubernetes in Kubernetes, is a tool that empowers you to create and manage isolated K3s clusters within your existing Kubernetes environment.

RamaLama is an open-source developer tool that simplifies the local serving of AI models from any source and facilitates their use for inference in production, all through the familiar language of containers.

HwameiStor is an HA local storage system for cloud-native stateful workloads. It creates a local storage resource pool for centrally managing all disks such as HDD, SSD, and NVMe. It uses the CSI architecture to provide distributed services with local volumes and provides data persistence capabilities for stateful cloud-native workloads or components.

The cloud ecosystem has reached a turning point. Tools for operators/administrators are now mature and can handle most day-to-day operations that deal with Kubernetes clusters. Finally, we can turn our focus to application developers and their needs.

If you look at all the Kubernetes tools available, you’ll understand that most of them treat Kubernetes as another form of infrastructure. You can easily find tools that install Kubernetes, monitor Kubernetes, secure Kubernetes, do cost estimations for Kubernetes, etc. But how many Kubernetes tools can you find that target application developers and their day-to-day responsibilities?

Several companies even try to hide Kubernetes completely from developers by using leaky abstractions or so-called developer portals. These adoption efforts almost always fail simply because nobody asked the developers what they really need. Don’t fall into this trap.

In this article, we see some common examples of what companies “think” about developers’ needs versus what developers need in practice, in the context of application development for Kubernetes.

Terraform state locking is a textbook example of solving a distributed coordination problem with the wrong primitive. You have concurrent actors, partial modifications, and dependency graphs—and the solution is a global mutex on a JSON blob. The scaling characteristics are exactly what you'd predict from this mismatch.

There are four key areas to consider when deciding on best practices for designing Terraform modules: scope, code strategy, security, and testing.

Fast caching software built from scratch with a focus on low latency and cpu efficency.

👉 На вебинаре вы узнаете:

💪 В результате вебинара вы:
-Научитесь разворачивать кластер PostgreSQL с Patroni и etcd.
-Поймёте архитектуру высокой доступности и роль каждого компонента.
-Сможете настроить автоматическое переключение master/replica при сбоях.
-Получите практическое понимание принципов отказоустойчивости баз данных

Like Vercel, but open source and for all languages.

Runtime Radar is an open-source solution for monitoring runtime security events and responding to incindents in containerized environments.

The tfswitch command-line tool lets you switch between different versions of Terraform.
If you do not have a particular version of Terraform installed, tfswitch will download and verify the version you desire.
The installation is minimal and easy.
Once installed, simply select the version you require from the dropdown and start using Terraform.

Linter for Postgres migrations & SQL

pgAdmin 4 is a rewrite of the popular pgAdmin3 management tool for the PostgreSQL

Deta Surf is an AI notebook that brings all your files and the web directly into your stream of thought.

It’s meant for simultaneous research and thinking that minimizes the grunt work: manually searching, opening windows & tabs, scrolling, copying and pasting into a document editor.

Surf is primarily built in Svelte, TypeScript and Rust, runs on MacOS, Windows & Linux, stores data locally in open formats, and is open source.

The goal of oxdraw is to make it easy to create and maintain high-quality diagrams using a declarative and reproducible syntax. Charts are written in Mermaid syntax, while a web interface allows users to fine-tune positions connector paths, colors, and other styling components. Whenever a diagram is tweaked visually, the structural changes are persisted back to the source file as declarative code so that everything remains deterministic and versionable. The changes are saved as comments in the mermaid file so it remains compatible with other Mermaid tools. The repo is composed of the Rust CLI to compile .mmd files into images and the React based web interface to editing the files.
