Kubernetes Playgrounds
Remote sandbox environments for learning and experimenting without worrying about setup and cleanup. Run anything on vanilla Linux VMs, get a fresh Docker host or Kubernetes cluster in seconds, publish ports, collaborate via sharing terminal sessions, SSH from the command line, and more.
Official Collection
Playgrounds crafted by iximiuz Labs for efficient hands-on learning and safe experimentation.
Kubernetes Cluster
A multi-node Kubernetes cluster provisioned with kubeadm, allowing you to choose your preferred container runtime and networking plugin. Perfect for CKA, CKAD, and CKS preparation.
Kubernetes Client (Go)
A collection of mini-programs demonstrating Kubernetes client-go usage and a loaded IDE. Handy if you need to write a controller or two.
Lightweight Kubernetes Cluster (K3s)
A single-node cluster with most of the K3s bells and whistles disabled.
Independent Authors
Playgrounds from outstanding independent authors proudly hosted by iximiuz Labs.
Kubernetes the Hard Way
A manually assembled Kubernetes cluster, inspired by Kelsey Hightower's "Kubernetes the Hard Way" tutorial.
kubeadm
A single-machine playground to experiment with kubeadm, a tool built to provide best-practice "fast paths" for creating Kubernetes clusters.
Community Collection
Playgrounds contributed by the community members sharing their knowledge and expertise.
OWASP K8s Vulnerable Cluster
This playground presents a k3s cluster that has randomized security vulnerabilities injected based on the OWASP top 10 kubernetes list. Run a scan to find what's wrong, then fix it and get another random vulnerability automatically injected. Play as long as you like!
ArgoCD + Gitea
Experiment with GitOps - deploy a demo app to a Kubernetes cluster with ArgoCD, with app manifests stored in a Git repo hosted in Gitea.
Kube-composer
Open-Source Kubernetes YAML Builder with Intuitive Web Interface and Dynamic Visualization for Developers and DevOps Engineers kube-composer.com
Getting Started with Istio
A simple K3s cluster with Istio service mesh and the sample Bookinfo app deployed. The playground is a good fit for workshops, self-paced labs, and quick experimentation with Istio and service mesh fundamentals.
Kind Cluster: Mutating Admission Policies
A playground to demonstrate dynamic admission control through native support for mutating resources during the admission phase through mutating admission policies.
Tailscale Homelab Access
A multi-node K3s cluster to demo connecting and troubleshooting a homelab remotely via tailscale. All username/passwords are admin/admin123
Kind Cluster: Structured AuthN + AuthZ Config
A playground to demonstrate access control through Kubernetes structured authentication and structured authorization configuration.
