DevOps Labs

This repository contains hands-on DevOps labs for application runtime, Kubernetes migration, and observability.

The repository is organized as a set of independent lab tracks. Each lab has its own README with the exact runbook, scope, and completion criteria.

Tracks

Track	Path	Status	Focus
Kubernetes	Kubernetes/	active	Containerized store application, Docker Compose, Kubernetes migration exercises
VictoriaMetrics Observability	Observability/VictoriaMetrics/	active	Metrics, logs, dashboards, alerts, Docker Compose observability stacks

Repository Layout

Kubernetes/
  Lab0/                # Store Lab application scaffold and Docker Compose runtime
  Lab1/                # First Kubernetes migration exercise with Pods and Services
  Lab2/                # Reserved for a later Kubernetes lab

Observability/
  VictoriaMetrics/
    Lab1/              # VictoriaMetrics metrics stack
    Lab2/              # VictoriaLogs + VictoriaMetrics integration stack

Common Tooling

Most labs assume:

• Docker and Docker Compose.
• A local Kubernetes cluster for Kubernetes migration labs.
• kubectl for Kubernetes verification.
• Python3 for small lab verification scripts.

Lab Conventions

• Each lab owns its own README.
• Kubernetes lab namespaces follow labN, for example lab1.
• Lab verification scripts live under each lab's tests/ directory when present.
• Educational starter manifests may be intentionally incomplete.
• Detailed run commands belong in the lab README closest to the files they operate on.

Quick Start

To run the application baseline:

cd Kubernetes/Lab0/app
docker compose up --build

To work on the first Kubernetes migration exercise:

cd Kubernetes/Lab1
python3 tests/verify_lab1.py --help

To run the first observability stack:

cd Observability/VictoriaMetrics/Lab1
docker compose -f deployment/docker/compose-vm-single.yml up -d
