commit-to-cluster

from git push to a cluster that pages someone at 3am when it breaks — and doesn't, because you built it right

Why "commit to cluster"

Most people learn Docker, get a container running locally, and call it DevOps. The actual job starts after that — getting from a developer's commit to a production cluster automatically, safely, and observably, without someone manually SSH-ing into a box at 11pm. That gap is what this repo is built around.

Status right now

Current phase: Phase 0 — Foundations Last updated: (edit this manually whenever you touch the repo)

Roadmap

Phase 0 — Foundations

• Linux fundamentals — CLI, permissions, processes, systemd
• Networking basics — DNS, HTTP/HTTPS, TCP/IP, how a request actually travels
• Git workflows — branching strategies, rebasing, resolving real conflicts
• Bash scripting — automating the boring stuff

Phase 1 — Containers

• Docker fundamentals — images, layers, why image size matters
• Writing efficient Dockerfiles — multi-stage builds, caching
• Docker Compose — multi-container local environments
• Container networking & volumes — what actually persists and why

Phase 2 — CI/CD

• GitHub Actions — build, test, deploy pipelines
• Artifact management — versioned builds, not just "latest"
• Automated testing in pipelines — failing fast on purpose
• Deployment strategies — blue-green, canary, rollback

Phase 3 — Infrastructure as Code

• Terraform — provisioning infra without clicking through a console
• Ansible — configuration management at scale
• Cloud basics — AWS/GCP core services, IAM, networking
• Environment parity — dev/staging/prod actually behaving the same

Phase 4 — Orchestration

• Kubernetes fundamentals — pods, deployments, services, ingress
• Helm — packaging and templating k8s manifests
• Secrets management — not hardcoding credentials, ever
• Service mesh basics — traffic management, mTLS

Phase 5 — Observability & Reliability

• Monitoring — Prometheus & Grafana
• Centralized logging — Loki / ELK
• Alerting that doesn't cry wolf
• SRE basics — SLIs/SLOs, incident response, postmortems

Phase 6 — Scale & Advanced Systems

• GitOps — ArgoCD / Flux, declarative deployments
• Multi-cluster / multi-region patterns
• DevSecOps — security scanning in the pipeline, hardened images
• Cost optimization, disaster recovery

Phase 7 — Capstone Projects

End-to-end pipelines pulling all of the above together. Tracked below.

This README gets edited constantly. The checkboxes, build log, and project table are the parts that should never go stale.
