Forgejo requirements at a glance
Forgejo is lightweight for normal Git hosting, but repository storage, database choice and Actions runners can change the hardware profile substantially.
- RAM
- No numerical official Forgejo server minimum published. Database and Actions runners can dominate whole-host memory.
- CPU
- No numerical official server core minimum. Git operations, indexing and CI jobs increase CPU demand.
- Storage
- No universal official minimum. Repositories, LFS, packages, attachments, database files and backups determine capacity.
- Database
- Forgejo defaults to SQLite if no database is configured; current Docker docs also provide MySQL and PostgreSQL examples.
- Actions
- Forgejo Runner is a separate workload. Job/service containers can consume large CPU/RAM unless explicit limits are configured.
- Best Zima starting point
- ZimaBoard 2 832 is a strong small-team Git host; use 16 GB or ZimaCube 2 when runners, LFS and larger repositories share the same machine.
From official requirements to the right setup
Size Forgejo itself first, then treat runners and repository storage as separate growth layers.
-
Official requirements
Start with Forgejo's official container image and persistent /data volume. If no external database is configured, Forgejo defaults to SQLite.
-
Confirm your needs
Estimate repository count, Git LFS/package usage and clone/fetch concurrency. These affect disk capacity, disk I/O and network traffic more than the web UI.
-
Leave room to grow
If enabling Forgejo Actions, budget runner CPU/RAM independently. Runner jobs execute in separate containers and should be constrained with container resource limits.
-
Run it on ZimaOS
On ZimaOS, use Install Custom App with the official Forgejo image, persist /data, map web/SSH ports, and move to PostgreSQL/MySQL when the deployment benefits from a separate database.

- Repository/LFS size
- Concurrent developers
- SQLite or external database
- Actions enabled
- Runner capacity/limits
- Backup retention

Official minimum requirements
Forgejo's current installation documentation does not publish a numerical host hardware minimum.
Do not invent a 1 GB or 2 GB official minimum. Core Forgejo is light, but repositories, databases and especially Actions runners need separate capacity planning.
| Requirement | Official minimum | What this supports |
|---|---|---|
| RAM minimum | No numerical official minimum published | Whole-host memory depends on database and optional runners. |
| CPU minimum | No numerical official minimum published | Git traffic and CI jobs change CPU demand. |
| Storage minimum | No numerical official minimum published | Repos, LFS, packages and backups determine capacity. |
| Default database | SQLite | Used when no external database is configured. |
| Other databases | MySQL and PostgreSQL | Current Docker docs provide both examples. |
| Official image | codeberg.org/forgejo/forgejo:16 | Current v16 Docker documentation. |
When to upgrade your hardware
Forgejo should scale when repository storage, Git concurrency or Actions runners exceed the current host envelope.
Actions jobs saturate CPU or RAM
LFS, packages or repositories grow rapidly
SQLite becomes a concurrency bottleneck
Git objects, LFS and package storage can become the primary disk workload.
Large monorepos, binaries and release artifacts.Higher multi-user/database activity may justify PostgreSQL or MySQL.
Growing shared Forgejo instances.Plan hardware growth with confidence
Scale Forgejo by separating repository storage, database activity and CI runners.
Put repositories and LFS on SSD-backed storage
Git object access and package operations benefit from fast durable storage.
Use SATA/NVMe with ZimaBoard 2 or SSD tiers on ZimaCube 2.Move to 16 GB when runners share the host
Extra RAM helps Forgejo, database and CI containers coexist.
ZimaBoard 2 1664.Use larger storage for LFS/packages and backups
Artifact retention can grow beyond the app/database footprint.
ZimaCube 2 Standard.Use stronger CPU or separate runner nodes for CI
Build/test jobs can dwarf the Forgejo web service itself.
ZimaCube 2 Pro or separate runner hardware.Can it run on ZimaOS?
Forgejo is not currently confirmed as a public official one-click ZimaOS App Store page in the sources checked for this guide. It can be deployed through Install Custom App using Forgejo's official image.
Custom install Forgejo in ZimaOS
Use Install Custom App with codeberg.org/forgejo/forgejo, persist /data, and map web plus SSH ports to available ZimaOS host ports.
Custom install Forgejo in the ZimaOS app ↗Use the official Forgejo container image
Forgejo documents Docker/Podman deployment and persistent data volumes directly.
Review Forgejo Docker installation ↗Limit Actions runner resources
When running CI, constrain job/service containers so they cannot consume all host CPU and memory.
Review Forgejo Actions resource controls ↗Choose Zima hardware for Forgejo
Forgejo itself is light; runners and repository/LFS storage usually determine when larger hardware becomes useful.
Is this primarily Git hosting, or will the same host also run CI runners and large artifact storage?
Small-team Git hosting
Use ZimaBoard 2 with SSD-backed repository storage.
- Best starting pointZimaBoard 2 832
- More headroomZimaBoard 2 1664
Git hosting plus CI/LFS/packages
Use more CPU, RAM and storage or separate runner nodes.
- Storage-first platformZimaCube 2 Standard
- Higher-processing headroomZimaCube 2 Pro
These are workload recommendations, not repository-count or CI-throughput guarantees.

Zima Blade Little yet Powerful
Maybe I am not digital natives but I live with PCs since 12 years old in 1984 when IBM PC clone come to my home. Many years have passed and many operating system I've tried. For me Zima blade and CasaOS was a quantum leap for home PC enthusiast and server lab machine to make me stay curious and relevant for this era.

Very good!!
I use ZimaCube Pro as 5th Proxmox cluster node. It runs several VMs and containers, including a VM with GPU passthrough to run a self-hosted LLM. A specific LXC container runs a Samba server for NAS capabilities using four of six RAID 6 SATA HDDs with ZFS.
★★★★★
Great innovation for mini server!
It is very useful and makes a powerful mini server for many purposes, including university and college students in engineering and electronics. Thank you so much for making this server.

Avaliação ZimaBoard 2
Construí um servidor de uso pessoal. O desempenho está muito bom e funciona perfeitamente onde quer que eu esteja. A surpresa é não dependermos de grandes estruturas para termos nosso próprio servidor de dados. Como iniciante, estou gostando bastante do ZimaOS, pois ele é simples e eficiente.
