DevOps&SRE Library

grpc-streams-checker

Synthetic monitoring for gRPC server-side streams — open each stream, verify frames actually arrive, and export Prometheus metrics.

k8s-mechanic

k8s-mechanic is a Kubernetes controller that watches your cluster for failures, investigates them automatically, and opens pull requests on your GitOps repository with proposed fixes — all without leaving your cluster. When a Pod is crash-looping, a Deployment is degraded, or a Node goes NotReady, mechanic spawns an in-cluster OpenCode agent that inspects the live cluster, locates the relevant manifests in your GitOps repo, determines the root cause, and opens a PR.

Ephemeral Environments: Automating QA for Reliable Cloud-Native Systems

Ephemeral environments are short-lived, isolated, fully provisioned, on-demand test environments created automatically from a pull request and destroyed the moment their job is done. This guide walks through why traditional environments fail, what ephemeral environments actually are, the modern stack that powers them, and a concrete, code-level blueprint for building your first ephemeral testing pipeline.

An 8-minute outage from a dead NLB and a JVM that cached DNS forever

We drained a Network Load Balancer during a planned migration, and one internal service kept hammering the dead IPs for 8 minutes. The cause wasn't the failover. It was a JVM caching the DNS record forever. The fix was a 30-second TTL and a health-check tweak, not a smarter system.

Dagster on Kubernetes: When More Nodes Won't Save You

You've scaled up your Kubernetes cluster. EC2 instances are running. CPU and memory metrics look reasonable. And yet — the number of completed Dagster runs stubbornly refuses to climb. This article walks through the full diagnostic journey — from the obvious knobs to the hidden PostgreSQL bottleneck that probably nobody warns you about.

OpenViking

OpenViking is an open-source context database for AI agents. It stores memories, resources, and skills as one virtual filesystem under the viking:// protocol, so an agent browses its own context with ls, tree, and find instead of querying a black-box vector store. Content is processed into three tiers — L0 abstract, L1 overview, L2 details — and loaded on demand. Every retrieval leaves a trajectory you can watch and debug.

kern

A fast, rootless sandbox and virtual resource runtime for any workload, including untrusted and AI-generated code. Daemonless: a real, kernel-enforced container in ~3.5 ms from an OCI image, no daemon, one 1.52 MB static binary.

⚡️⚡️Инциденты, метрики и спасенный прод на DevOops 2026 Даже самая отказоустойчивая инфраструктура иногда преподносит сюрпризы, а один неудачный коммит может устроить всей команде долгий вечер. На DevOops 2026 будут разбирать, что делать с такими ситуациями в реальной инфраструктуре: от проблем с Kubernetes и GitOps до инцидентов, метрик и observability. Программный комитет выбрал восемь докладов, которые рекомендует посмотреть в первую очередь. Здесь — Kafka в Kubernetes, архитектура корпоративного GPT, GitOps без лишнего blast radius, security-политики, надежность, DORA и observability. Все подробности — в карточках и на сайте. 🔥С промокодом devopslibrary персональные билеты дешевле Купить билет

tig

Tig is an ncurses-based text-mode interface for git. It functions mainly as a Git repository browser, but can also assist in staging changes for commit at chunk level and act as a pager for output from various Git commands.

spiderpool

Spiderpool is an underlay and RDMA network solution for the Kubernetes. It enhances the capabilities of Macvlan CNI, ipvlan CNI, SR-IOV CNI, fulfills various networking needs, and supports to run on bare metal, virtual machine, and public cloud environments. Spiderpool delivers exceptional network performance, particularly benefiting network I/O-intensive and low-latency applications like storage, middleware, and AI.

workmux

Giga opinionated zero-friction workflow tool for managing git worktrees and tmux windows as isolated development environments. Perfect for running multiple AI agents in parallel without conflict.

celld

celld is an open-source daemon that runs Cloudflare Workers and Durable Objects on your own machines. Each object is its own SQLite database. celld addresses an object by name and replicates it to a bucket that you own. The bucket can be S3-compatible or Google Cloud Storage. The nodes coordinate through that bucket alone, with no control plane and no consensus. Because every object is its own small database, applications shard by construction — the contention and blast-radius failures of one shared database are designed out, not managed. A cell that no node holds is inactive, and an inactive cell costs nearly nothing.

git-knife

Stab your git history into shape — every commit's message, author, and dates, edited like a table.
