Tools for DevOps and Cloud work

Start with these 16

• awesome-selfhosted: services you can run yourself

  A long, well-sorted catalogue of free software you can host on your own machines, grouped by what it replaces: wikis, monitoring, chat, media, backups and much more. Useful for homelab ideas and for finding a mature project to read. Start with README.md for the categories; non-free.md keeps proprietary entries separate so the main list stays clean.

• kubernetes-the-hard-way: build a cluster by hand

  A classic tutorial that sets up Kubernetes step by step without installers, so you meet certificates, the API server, etcd and kubelet configuration directly. The numbered files in docs/ are the path; units/ and configs/ hold the files you generate or install. Not updated recently, but the concepts remain valid and the repo is still worth working through once. License: Apache-2.0.

• awesome-compose: Docker Compose samples for common stacks

  Ready-made Compose setups for pairings like Flask with Redis, Django, Nginx with Go and MySQL, Elasticsearch with Kibana, and more. Each sample is a folder with its own compose.yaml-style config, so you can copy only what you need. Handy for learning multi-container networking and volumes by running real examples.

• starter-workflows: GitHub Actions templates by use case

  The official source of the workflow suggestions GitHub shows when you set up Actions. Folders like ci/, code-scanning/ and deployments/ hold YAML for building and testing many languages, scanning code and deploying to clouds. Read a few to learn caching, matrices and permissions idioms. License: MIT.

• microservices-demo: Online Boutique on Kubernetes

  A polyglot web shop split into small services that talk over gRPC, designed to demonstrate cloud-native tooling. Start with kubernetes-manifests/ and skaffold.yaml to run it, then read service code under src/ and the API contracts in protos/. terraform/ and kustomize/ show alternative ways to deploy. License: Apache-2.0.

  github.comFull AppIntermediate

• awesome-docker: containers, tooling and learning resources

  A curated map of the Docker ecosystem: tooling, security scanners, orchestration, CI helpers and tutorials. Read README.md by section when you hit a specific problem such as image size or registry choice. Alongside the list there is Go code in cmd/ and internal/, plus a website/ folder.

  github.comAwesome ListBeginner

• ansible-for-devops: playbooks that grow with the book

  Example playbooks from a well-known Ansible book, from simple to multi-server setups. Begin with first-ansible-playbook/, then lamp-infrastructure/, deployments-rolling/ and molecule/ for testing roles. The author notes that not every example follows every best practice, since each one illustrates a feature. Not updated every month, but the lessons last. License: MIT.

  github.comLearningIntermediate

• opentelemetry-demo: a shop instrumented end to end

  A multi-language storefront built to show traces, metrics and logs in practice. Look through src/ to see the same telemetry ideas applied in different languages, and open compose.yaml for the local stack. A strong reference for observability wiring. License: Apache-2.0.

  github.comFull AppIntermediate

• terraform-aws-vpc: a module worth copying habits from

  A widely used Terraform module for AWS networking. Read main.tf, variables.tf and outputs.tf for how a flexible module exposes options, then run the scenarios in examples/ and look at modules/. A good lesson in module design and interface choices. License: Apache-2.0.

  github.comTemplateIntermediate

• podinfo: a small Go service for Kubernetes demos

  A tiny web service used to try out deployment patterns. The repo includes Helm in charts/, plain manifests in kustomize/, a timoni/ module and signing config in .cosign/. Deploy it to learn rollout, health checks and supply-chain tooling. License: Apache-2.0.
