How much RAM does Zot need?

Plan on 1–2 GB for typical use; add headroom if you expect many concurrent users.

What stack does Zot run on?

Single Go binary + filesystem/S3.

Yes — size the plan so Zot plus your other workloads fit in RAM with room to spare.

Development

A minimal, scalable OCI-native container registry.

A lightweight registry that speaks the OCI distribution spec, with a tiny footprint and no database dependency.

Zot is the simplest way to get a private registry running — one binary, minimal resources, no external database.

1
Provision a VPS
Pick a Debian/Ubuntu template and get root SSH in about a minute.
2
Install the runtime
Install Single Go binary + filesystem/S3.
3
Deploy the application
Net what you need from the project’s official source and run it.
4
Put it behind TLS
Reverse-proxy with Nginx and issue a Let’s Encrypt certificate.
5
Add it to your backups
Include the data directory and database in your backup routine before you rely on it.

Give Zot its own database user with rights only on its own schema.
Reverse-proxy Zot and terminate TLS at the proxy so certificates are managed in one place.
Take a VPS snapshot before major upgrades so you can roll back cleanly.
Keep Zot patched — most self-hosting incidents are unpatched software.
