Kubernetes Workshop – Overview

Overview

This workshop covers the path from container orchestration fundamentals to secure, production-oriented platform operations.

The workshop focuses on:

  • Kubernetes architecture
  • declarative resources
  • workloads
  • networking
  • storage
  • scheduling
  • observability
  • GitOps
  • multi-tenancy
  • security hardening
  • incident response

The content can be used as a learning path, workshop material, reference documentation, or foundation for internal training.

Quickstart

This quickstart takes you from choosing a lab environment to starting the first exercise.

Use the Workshop Material

The material is available in the Orthevs Wiki. Practice modules can be downloaded as ZIP files from the workshop page.

Select a Lab Environment

Choose a suitable environment for your labs:

Environment Description Documentation
WSL For Windows systems using Ubuntu on WSL Set up Ubuntu on WSL
VM For local or remote Ubuntu VMs Set up Ubuntu in a VM
Bare Metal For direct installation on physical hardware Set up Ubuntu on bare metal
Existing Cluster For prepared Kubernetes test clusters Prepare cluster access

Provision the Lab Environment

Install the required base tools with the existing setup files:

If a provisioning script exists, check it in dry-run mode first:

bash
chmod +x scripts/provision_kubernetes.sh
./scripts/provision_kubernetes.sh --dry-run
sudo ./scripts/provision_kubernetes.sh

Verify the Cluster

After setup, verify that kubectl points to your Kubernetes cluster:

bash
kubectl version --client
kubectl cluster-info
kubectl get nodes
kubectl get namespaces

If you work locally with kind, minikube, or k3d, use the existing environment and command documentation:

Start the Workshop

Start with the curriculum and then continue through the workshop levels:

  1. Read the curriculum
  2. Start Fundamentals
  3. Open exercises
  4. Run examples
  5. Prepare assessments

Recommended order:

Audience

This workshop is intended for:

  • developers
  • DevOps engineers
  • system engineers
  • platform engineers
  • SREs
  • cloud engineers
  • tech leads
  • security engineers

The goal is to understand Kubernetes conceptually, operate it in realistic environments, and secure it properly.

Learning Path

Level Focus Outcome
Fundamentals architecture, control plane, nodes, pods, deployments, services, namespaces, labels, selectors, kubectl You understand the core concepts and can create and inspect simple resources.
Intermediate workloads, ConfigMaps, Secrets, probes, requests/limits, HPA, ingress, DNS, storage, scheduling, Helm, Kustomize You can operate typical application workloads declaratively.
Professional cluster architecture, distributions, etcd, lifecycle, CNI/CSI, observability, GitOps, add-ons, multi-tenancy, autoscaling, cost management, backup You understand Kubernetes as a platform and can classify operational concerns.
Advanced + Security threat modeling, RBAC, service accounts, API server, etcd security, Pod Security Standards, NetworkPolicies, admission control, image security, runtime security, incident response You can operate Kubernetes more securely and analyze typical attack and failure scenarios.

Language and Code Convention

  • Markdown content is maintained in German and English, separated by language.
  • The German version uses direct du wording.
  • Code, commands, file names, variables, and code comments stay in English.
  • Production clusters, secrets, tokens, private keys, and customer data must not be used in labs.
  • Example values must be clearly recognizable as dummy values.
  • Workshop files should follow consistent technical naming.
11 / 13

Working Mode

Create a Branch

Do not work directly on main or master. Use a descriptive branch with username and topic:

bash
git checkout -b workshop/<username>/<topic>

Example:

bash
git checkout -b workshop/alex/kubernetes-networking-lab

Changes should be reviewed through a pull request or merge request.

Security and Credential Notes

  • Do not commit passwords.
  • Do not commit tokens or API keys.
  • Do not commit SSH private keys.
  • Do not commit .env files with real secrets.
  • Do not commit kubeconfig files with production credentials.
  • Do not use customer data or production cluster dumps.
  • Use dummy values in example configurations.
  • Check .gitignore before adding new examples.

Run Scripts

Check provisioning in dry-run mode first:

bash
chmod +x scripts/provision_kubernetes.sh
./scripts/provision_kubernetes.sh --dry-run

If the output is plausible, run provisioning:

bash
sudo ./scripts/provision_kubernetes.sh

sudo is only required for package installation. Scripts must not execute destructive reset actions without explicit confirmation.
