Control-plane server
| Setup | CPU | Memory | Storage |
|---|---|---|---|
| Minimum | 2 vCPU | 2 GB | 20 GB |
| Recommended | 2 vCPU | 4 GB | 40 GB |
- A Linux server you administer, with SSH access and root or sudo for installation.
- Docker with the Compose plugin. Node.js 20 or later for the installer CLI. The bootstrap script can install these prerequisites.
- A domain, access to its DNS records and a DNS provider API token for certificate issuance.
- Network access to download deployment files, container images and certificate dependencies.
Worker machines
Firetower runs agents directly, without a container per agent. CPU and memory needs depend on your agents, tasks and how many run at once.
A Mac mini with 16 GB of memory is a practical starting point. A VPS with 8 GB or less can also work for lighter tasks. Builds, tests and large repositories may need more.
Workers support macOS and Linux on arm64 and x86_64. On Windows, run the worker inside WSL2.
- SSH reachable from the control plane, using a dedicated account for agent work.
- git, tmux, a POSIX shell, curl and tar.
- The coding agents and project tools needed by your tasks.
- Access to your git hosts, agent providers and project dependencies.
People and devices
Provide a reachable HTTPS URL and a Firetower account for each person. Install the company VPN on every device that needs private access.
Next: install Firetower.
