Linux 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.
USE Practice
Practice Linux USE-method investigations against randomized host-level scenarios. Run `use-practice` to see what the options are, and put some load on the system to practice your USE methodology investigation skills. It already has the use-tool (https://github.com/lpmi-13/use-tool) installed, so you can begin with that, or just run a free-form investigation.
SilverStack Dev Machine
A fully provisioned DevOps workstation on Ubuntu 24.04 - every tool pre-installed, every alias pre-wired, zero setup required.
SilverStack Nexus Server
Production-grade Nexus Repository Manager 3 Community Edition on Ubuntu 24.04 - systemd-booted, Cloudflare-ready, Nginx-proxied, zero setup required.
SilverStack SonarQube Server
Production-grade SonarQube 26.2 CE (LTA) on Ubuntu 24.04 - systemd-booted, PostgreSQL-backed, Nginx-proxied, Cloudflare-ready, zero setup required.
SilverStack Jenkins Server
Production-grade Jenkins LTS on Ubuntu 24.04 - systemd-booted, Nginx-proxied, Cloudflare-ready, zero setup required.
SilverStack CI/CD Stack
A fully composed 4-node CI/CD platform - Jenkins, SonarQube, Nexus, and a Dev Machine, all running in a single Flexbox playground on a shared private network. Each service is Nginx-proxied and Cloudflare-ready. Zero setup required.
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 💻🌐
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.
