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.
Experiment with the Nix package manager, a powerful tool for reproducible and isolated software environments, on Ubuntu.
OpenSearch is an open-source, enterprise-grade search and observability suite that brings order to unstructured data at scale.
A single-machine playground to experiment with kubeadm, a tool built to provide best-practice "fast paths" for creating Kubernetes clusters.
A distributed, reliable key-value store for the most critical data of a distributed system.
Secure, store, and tightly control access to tokens, passwords, certificates, encryption keys for protecting secrets, and other sensitive data using a UI, CLI, or HTTP API.
A multi-node K3s cluster to demo connecting and troubleshooting a homelab remotely via tailscale. All username/passwords are admin/admin123
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 UIāperfect for learning and experimentation.
This playground installs the base_container_sec_workstation.yml playbook from https://github.com/raesene/container_sec_workstation
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.
