DevOps 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.
Community Collection
Playgrounds contributed by the community members sharing their knowledge and expertise.
Log Parser
A playground that generates one log parsing activity at a time, and regenerates a new one when you complete each activity. It uses authentic log formats such as nginx access logs and syslog entries to simulate real parsing needs. The operator avoids repeats until it has exhausted the full activity list, then starts a new randomized cycle. Github: https://github.com/lpmi-13/logparser-lab-operator
Full Ubuntu Desktop Experience in web
Access your remote server’s full desktop directly from the browser using Apache Guacamole, eliminating the need for a local RDP client 💻🌐
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!
Coder Development Environment
A fully configured Coder instance running on Ubuntu 24.04 with Docker support. Uses a custom OCI image with pre-installed Coder and Docker.
PostgreSQL 18.x.y on Ubuntu 24.04 (customized)
PostgreSQL 18.x.y Playground with Ubuntu 24.04 OS (customized)
Uncloud Cluster
A multi-node Uncloud cluster with a standalone control node. About Uncloud: https://github.com/psviderski/uncloud
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.
Docker on Btrfs
Hands-on Docker on Btrfs: experiment with native snapshots, compression, and checksums; inspect setup, grow the filesystem live, and back up/restore images and containers.
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
ELK Stack
This is a hands-on ELK (Elasticsearch, Logstash, Kibana) playground enhanced with Docker and Beats to simulate real-world log and observability scenarios. It includes an Elastic Cluster (es-node-01 and es-node-02) for storing and indexing data, a test-node-03 running Docker with Filebeat, Metricbeat, and Heartbeat for log and metric collection, and kibana-node-04 for visualizing everything via Kibana UI—perfect for learning and experimentation.
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.
ArgoCD with K3s 🎯
Welcome to the ArgoCD Playground, a lightweight K3s cluster pre-configured with ArgoCD for GitOps-based continuous deployment, Helm for package management, and the ArgoCD CLI for managing applications via the terminal.
