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.

Playgrounds contributed by the community members sharing their knowledge and expertise.
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.
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
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!
Tailscale Homelab Access
A multi-node K3s cluster to demo connecting and troubleshooting a homelab remotely via tailscale. All username/passwords are admin/admin123
