bregman-arie/devops-exercises

A huge, community-built bank of DevOps and SRE interview questions — This repository collects over 2,600 exercises and questions spanning Linux, Kubernetes, Terraform, networking, Git and more. Organized by topic with contributions accepted via pull request, it's aimed at people preparing for DevOps/SRE interviews or wanting to self-assess their knowledge, though it explicitly isn't meant to be studied end-to-end.

hashicorp/terraform

Terraform: infrastructure as code with graph-based planning — Terraform codifies APIs into declarative configs so infrastructure changes can be planned, reviewed, and versioned like code. Its resource graph parallelizes non-dependent changes and execution plans show exactly what will happen before apply, helping ops teams avoid surprises across providers.

MichaelCade/90DaysOfDevOps

A three-year community map for learning DevOps from scratch — Started as a personal 90-day learning-in-public challenge, this repo has grown into a structured, multi-year curriculum covering DevOps principles, DevSecOps, and community-contributed sessions. It's free and vendor-neutral, built on open source tooling, and useful for anyone building foundational DevOps knowledge through reading, videos, and contributed resources.

GoogleCloudPlatform/microservices-demo

Online Boutique: an 11-service playground for Google Cloud tooling — Online Boutique is Google's reference e-commerce app, now spanning 11 gRPC microservices used to demo GKE, Cloud Service Mesh, Spanner, AlloyDB and even Gemini integration. It runs on any Kubernetes cluster, making it a practical sandbox for developers learning service mesh, observability and cloud-native patterns.

coder/coder

Self-hosted workspaces that now run AI coding agents too — Coder provisions cloud development environments via Terraform and connects them through WireGuard, shutting down idle resources automatically. Its newer Coder Agents feature runs AI coding agents (Anthropic, OpenAI, Google, Bedrock, or self-hosted models) on your own infrastructure, with no API keys exposed in workspaces and centralized audit logging.

mikefarah/yq

A jq-style processor that speaks YAML, JSON, XML and more — yq brings jq-like query syntax to YAML, JSON, XML, CSV, TOML, HCL and properties files. It's a dependency-free Go binary, so it's handy for scripting, in-place edits, merging multiple files, and converting between formats in DevOps workflows.

semaphoreui/semaphore

A web control panel for running Ansible, Terraform, and scripts at scale — Semaphore UI gives teams a web interface and API for running Ansible playbooks, Terraform/OpenTofu/Terragrunt code, Bash and PowerShell scripts, replacing ad-hoc terminal deployments. It adds projects, reusable task templates, schedules, inventories, and access control, aimed at teams whose deployment workflows have outgrown manual CLI use.

hashicorp/terraform-provider-aws

E2B open-sources the microVM backend behind its AI agent cloud — E2B has released the Go runtime powering its agent cloud: control-plane API, orchestrator, in-VM agent, edge router and template builder. Sandboxes are resumed Firecracker snapshots rather than freshly booted VMs, with memory paged in lazily via userfaultfd. Apache-2.0 licensed, runnable as a single-machine Embed package, enterprise deployment, or the public cloud.

nishikawaakira/waf-dojo

Learn AWS WAF by Fighting Simulated Attacks, Not Reading Docs — WAF Dojo is a Go-based hands-on trainer where you configure real AWS WAF rules against live simulated attacks, first via guided tutorials then in a game mode scored on blocked attacks vs. false positives.
