Jenkins VPS Hosting on Offshore Infrastructure

Managed CI platforms (GitHub Actions, GitLab.com SaaS, CircleCI) apply quota limits, artifact retention caps, and concurrent job ceilings that can stop a real release cold. They also see every line of source code that passes through the pipeline. For teams building things that do not fit a Silicon Valley acceptable-use policy - reverse engineering tooling, sanctions-adjacent fintech, adult-content automation, scraping pipelines - those managed platforms will eventually suspend you with no appeal. A self-hosted Jenkins controller on an offshore VPS sidesteps all of that. Your jobs, your build artifacts, your secrets, and your worker logs stay on a server you control in a jurisdiction without mandatory log retention for VPS operators. Pull from any git remote, push to any artifact registry, and run any binary your build needs. The Jenkins controller process needs about 2 GB RAM and one steady CPU core to run comfortably for a small team; the Romania VPS Pro or Iceland VPS at 4 GB RAM gives you plenty of headroom for an internal Jenkins plus a couple of agent containers on the same host. Crypto payment via BTC, ETH, XMR, or USDT means your infrastructure provider does not link your build pipeline to a corporate bank account. Combined with offshore jurisdiction and no KYC at signup, your CI/CD attack surface from a discovery and legal standpoint shrinks to almost nothing. You are paying for compute, not for a marketing relationship.

The Jenkins controller (the web UI, scheduler, and plugin host) is mostly RAM bound. A small team with 5 to 15 active jobs and 100 to 300 historical builds retained can run comfortably on 2 vCPU and 4 GB RAM. Heavier shops with hundreds of jobs and dozens of plugins (Blue Ocean, Pipeline, Kubernetes, Configuration as Code) should plan on 4 vCPU and 8 GB RAM minimum. Disk is usually the binding factor over time because build logs, artifact archives, and the workspace directory grow steadily. Allocate at least 100 GB SSD and prune aggressively with a retention strategy in each Jenkinsfile. Agents are where actual builds run, and the right model is to run agents in disposable containers or short-lived VMs rather than directly on the controller. Spin up a second offshore VPS as a docker-based agent host, or use the docker-plugin to launch ephemeral build containers per job on the same VPS. A typical build container needs 1 to 2 GB RAM and 1 to 2 vCPU. For compile-heavy jobs (Rust, C++, full Node monorepos), step up to 4 GB RAM and 4 vCPU per agent. Network throughput matters when you pull large base images or push artifacts. AnubizHost VPS plans ship with 1 Gbps unmetered uplinks on most tiers. For Docker image builds in particular, an SSD-backed VPS in a 1 Gbps location like Iceland or Romania will outperform a managed CI runner that throttles bandwidth after a few hundred MB.

After provisioning your VPS, update the base system: `apt update && apt upgrade -y`. Install OpenJDK 17, the recommended LTS Java for current Jenkins: `apt install -y openjdk-17-jre-headless`. Add the Jenkins apt repository and key, then install: `curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null && echo "deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian-stable binary/" > /etc/apt/sources.list.d/jenkins.list && apt update && apt install -y jenkins`. The systemd service auto-starts on port 8080. Do not expose port 8080 directly. Put Jenkins behind a TLS-terminating reverse proxy. The fastest path is Caddy: `apt install -y caddy`, then write `/etc/caddy/Caddyfile` with `ci.yourdomain.tld { reverse_proxy localhost:8080 }`. Caddy fetches and renews Let's Encrypt automatically. Open only ports 80, 443, and your SSH port through ufw: `ufw allow 80,443/tcp && ufw allow 22/tcp && ufw enable`. Lock the admin account immediately. Retrieve the initial admin password with `cat /var/lib/jenkins/secrets/initialAdminPassword`, finish the setup wizard, install only the plugins you actually need, then disable signup and enable matrix-based authorization. Set the Jenkins URL in Manage Jenkins -> System to match your TLS hostname so generated build links are correct. Add `-Dhudson.security.csrf.GlobalCrumbIssuerConfiguration.DISABLE_CSRF_PROTECTION=false` to JAVA_OPTS in `/etc/default/jenkins` to ensure CSRF protection stays on after upgrades.
