Gubernator v2.13.0: Google SRE SLOs, Native CoreDNS Suite & Caddy Ingress for Docker Compose

If you love the simplicity of Docker Swarm (native Compose files, lightweight single binary) but miss the advanced capabilities of Kubernetes (targeted label placement, SRE-grade observability, built-in DNS service discovery, and zero-trust ingress), meet Gubernator (gbnt) . We are excited to release Gubernator v2.13.0 , introducing three massive feature suites natively integrated into a single binary and a modern Material Design 3 Flutter Web Dashboard: Google SRE Multi-Burn-Rate SLO Engine & Interactive Suite CoreDNS 4-Tab Management Suite & Interactive Dig Playground Caddy Ingress & Zero-Trust Reverse Proxy Suite Fun Fact: The entirety of Gubernator's codebase, multi-node deployment pipelines, and SRE features were designed, built, and pair-programmed using **Google Antigravity (AGY) , Google DeepMind's agentic AI coding assistant! Let's dive into what's new and how you can level up your self-hosted or production container clusters! 1. Google SRE Multi-Burn-Rate SLO Engine & Web Suite Defining Service Level Objectives (SLOs) and tracking Error Budgets is the gold standard of Site Reliability Engineering. Until now, implementing SLOs meant running heavy Kubernetes CRDs (via tools like Sloth or Pyrra) or using costly SaaS platforms. Gubernator v2.13.0 brings Google SRE Workbook (Chapter 5) compliant multi-burn-rate alerting straight to simple docker-compose.yml services: version : " 3.8" services : payment-api : image : hashicorp/http-echo:latest labels : gbnt.slo.enable : " true" gbnt.slo.target : " 99.9" gbnt.slo.window : " 30d" gbnt.slo.template : " caddy-http" gbnt.slo.journey : " Checkout Flow" What makes Gubernator's SLO Suite unique? Google Multi-Burn-Rate Alerting : Automatically generates standard 4-window Prometheus recording and alert rules ( Critical Page 1h/6h & Warning Ticket 3d/14d ). Dynamic "No-Code" Management : Click "+ Configure / Add SLO" in the Web UI or call POST /v1/slo/edit to create, edit, or disable SLOs on the fly without editing Compose
