A node autoscaler project for Proxmox allowing a Kubernetes cluster to dynamically scale across a Proxmox cluster.

The local volume static provisioner manages PersistentVolume lifecycle for pre-allocated disks by detecting and creating PVs for each local disk on the host, and cleaning up the disks when released. It does not support dynamic provisioning.

Alaz is an open-source Ddosify eBPF agent that can inspect and collect Kubernetes (K8s) service traffic without the need for code instrumentation, sidecars, or service restarts. This is possible due to its use of eBPF technology.

Alaz can create a Service Map that helps identify golden signals and problems like:

- High latencies between K8s services
- Detect 5xx HTTP status codes
- Detect Idle / Zombie services
- Detect slow SQL queries

Dragonfly Operator is a Kubernetes operator used to deploy and manage Dragonfly instances inside your Kubernetes clusters.

Helm Compose is a tool for managing multiple releases of one or many different Helm charts. It is heavily inspired by Docker Compose and is an extension of the package manager idea behind Helm itself. It allows for full configuration-as-code capabilities in an single yaml file.

Kube Metrics Adapter is a general purpose metrics adapter for Kubernetes that can collect and serve custom and external metrics for Horizontal Pod Autoscaling.

Zellij is a workspace aimed at developers, ops-oriented people and anyone who loves the terminal. Similar programs are sometimes called "Terminal Multiplexers".

Zellij is designed around the philosophy that one must not sacrifice simplicity for power, taking pride in its great experience out of the box as well as the advanced features it places at its users' fingertips.

Alacritty is a modern terminal emulator that comes with sensible defaults, but allows for extensive configuration. By integrating with other applications, rather than reimplementing their functionality, it manages to provide a flexible set of features with high performance. The supported platforms currently consist of BSD, Linux, macOS and Windows.

A GPU-accelerated cross-platform terminal emulator and multiplexer written by @wez and implemented in Rust

A data hoarder’s dream come true: bundle any web page into a single HTML file. You can finally replace that gazillion of open tabs with a gazillion of .html files stored somewhere on your precious little drive.

Unlike the conventional “Save page as”, monolith not only saves the target document, it embeds CSS, image, and JavaScript assets all at once, producing a single HTML5 document that is a joy to store and share.

If compared to saving websites with wget -mpk, this tool embeds all assets as data URLs and therefore lets browsers render the saved page exactly the way it was on the Internet, even when no network connection is available.

Lapdev is a self hosted application that spins up remote development environments on your own servers or clouds. It scales from a single machine in the corner to a global fleet of servers. It uses Devcontainer open specification for defining your development environment as code. If you’re interested in a deep dive into how Lapdev works, you can read about its architecture here.

GritQL is a declarative query language for searching and modifying source code.

An open source virtual hand-drawn style whiteboard.

Our nine month journey to horizontally shard Figma’s Postgres stack, and the key to unlocking (nearly) infinite scalability.

Figma’s database stack has grown almost 100x since 2020. This is a good problem to have because it means our business is expanding, but it also poses some tricky technical challenges. Over the past four years, we’ve made a significant effort to stay ahead of the curve and avoid potential growing pains. In 2020, we were running a single Postgres database hosted on AWS’s largest physical instance, and by the end of 2022, we had built out a distributed architecture with caching, read replicas, and a dozen vertically partitioned databases. We split groups of related tables—like “Figma files” or “Organizations”—into their own vertical partitions, which allowed us to make incremental scaling gains and maintain enough runway to stay ahead of our growth.

Garnet is a remote cache-store from Microsoft Research that offers strong performance (throughput and latency), scalability, storage, recovery, cluster sharding, key migration, and replication features. Garnet can work with existing Redis clients.

Kubernetes has been a great orchestrator of Jobs and CronJobs for over half a decade now, but if you had a need for running proxy containers or other secondary containers alongside the job, running things properly took a bit of work and decision-making to handle gracefully.

This article introduces the easiest way to run Jobs with sidecars using the latest Kubernetes features, and has a complementary repository with complete example manifests you can try in your own cluster. The repository contains all the examples for earlier versions of K8s as well, so make sure to focus on the cronjob.sidecar.*.yaml examples.

A key challenge of monitoring your CI/CD system is understanding how to optimize your workflows and create best practices that help you minimize pipeline slowdowns and better respond to CI issues. In addition to monitoring CI pipelines and their underlying infrastructure, your organization also needs to cultivate effective relationships between platform and development teams. Fostering collaboration between these two teams is a critical and equally valuable aspect of improving the reliability and performance of your CI.

In this post, we’ll explore how platform teams can help developers visualize trends in CI test performance and notify them of new flaky tests, test failures, and performance regressions with dashboards and monitors. We’ll also detail best practices that can help developers identify, investigate, and remediate flaky tests.

Core principles of documentation-as-code tools

- Treating documentation with the same rigor as code
- Storing documentation in version control
- Automation of documentation generation and deployment
- Peer review processes for documentation updates
