Kubernetes Playgrounds
Remote sandbox environments for learning and experimentation — without setup or cleanup. Launch fresh Linux VMs, Docker hosts, or Kubernetes clusters in seconds, publish ports, share terminal sessions, and connect over SSH.
Community Collection
Playgrounds contributed by the community members sharing their knowledge and expertise.
GitOps Bootstrap
A sandbox where you can experiment with different k8s stacks all you want!
Cloud Tracing Lab
Diagnose realistic distributed tracing scenarios in a preloaded k3s VM, for users to get more familiar with traces in general and jaeger-ui specifically. There's guided investigation through distributed traces, along with identification of slow spans and comparing two traces to identify what changed to make it slow down.
OWASP K8s Vulnerable Cluster
This playground presents a k3s cluster that has randomized security vulnerabilities injected based on the OWASP Kubernetes Top 10 list for 2025. 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
Tailscale Homelab Access
A multi-node K3s cluster to demo connecting and troubleshooting a homelab remotely via tailscale. All username/passwords are admin/admin123
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.
Kind Cluster: Structured AuthN + AuthZ Config
A playground to demonstrate access control through Kubernetes structured authentication and structured authorization configuration.
Kind Cluster: OIDC AuthN
A playground to demonstrate access control through OIDC authentication for Kubernetes.
2048 Game (Kubernetes Edition)
A sample app from https://github.com/digitalocean/kubernetes-sample-apps running on an iximiuz Labs K3s cluster.
