SilverStack CI/CD Stack Playground
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.
Nodes
| Node | Image | CPU | RAM | Disk | Role |
|---|---|---|---|---|---|
dev-machine | dev-cicd-rootfs | 1 vCPU | 1 GiB | 30 GiB | Jump host · entry point |
jenkins-server | jenkins-rootfs | 3 vCPU | 4 GiB | 40 GiB | Jenkins LTS · CI/CD orchestrator |
sonarqube-server | sonarqube-rootfs | 3 vCPU | 6 GiB | 40 GiB | SonarQube 26.2 CE + PostgreSQL 18 |
nexus-server | nexus-rootfs | 3 vCPU | 5 GiB | 40 GiB | Nexus 3.89.1 CE · artifact registry |
Total: 10 vCPU · 16 GiB RAM · 150 GiB disk - exactly the Flexbox budget.
How it works
All four nodes share a local network (172.16.0.0/24). SSH directly between nodes
by name from the Dev Machine:
ssh jenkins-server then follow steps → jenkins.yourdomain.com
ssh sonarqube-server then follow steps → sonar.yourdomain.com
ssh nexus-server then follow steps → nexus.yourdomain.com
Each service is accessible via a dedicated UI tab in the playground (port 80 via Nginx).
For public access on your own domain, cloudflared is pre-installed on each service node.
Tabs
8 tabs pre-defined: IDE · dev · jenkins · sonarqube · nexus terminals + Jenkins UI · SonarQube UI · Nexus UI
- The ↗ arrow on each UI tab opens the service in a new browser tab - but only after the tab has been clicked and loaded inside the lab first.
Boot times (first boot)
| Service | Wait time |
|---|---|
| Jenkins | ~60–90 s |
| SonarQube | ~2–3 min (Elasticsearch) |
| Nexus | ~60–90 s |
Resources · 10 vCPU / 16 GiB RAM / 150 GiB disk (Flexbox)
