Containers, done safely

Docker & container workloads

Run Docker and Compose inside a Cube that has its own kernel. Your containers get a full, isolated microVM to live in — not a slice of someone else's host.

01Why a Cube

Why run this on a Cube

Every line here is enforced by the platform rather than left to you: its own kernel per Cube, RAM and disk reserved 1:1, and full outbound access while nothing reaches in until you open a port — each one IP-allowlistable.

01

Your own kernel for your containers

Install the Docker engine and run any image with full root. Because the Cube brings its own kernel, your container host is isolated by design rather than sharing a kernel with other tenants.

02

Compose whole stacks

Run multi-container apps with Docker Compose — web, worker, cache, and database side by side inside a single Cube you fully control.

03

Reachable on your own domain

Point a custom domain at your containerised app with one CNAME and get automatic HTTPS. Web traffic enters through managed ingress, so the Cube is never exposed directly.

04

Snapshot the whole host

Take a live snapshot of the entire Cube — engine, images, and volumes — and restore it instantly to roll back or clone your setup.

02Setup

How it works on a Cube

Treat a Cube as your container host and deploy your stack onto it.

  1. 01

    Create a Cube with the CPU, RAM, and disk your images need.

  2. 02

    SSH in as root and install the Docker engine and Compose.

  3. 03

    Bring up your stack with docker compose up, then map a custom domain for automatic HTTPS.

  4. 04

    Snapshot the Cube once it's healthy so you can restore or clone it later.

03Answers

Frequently asked questions

Do I get real Docker, or a limited runtime?

Real Docker. You have full root on the Cube, so you install and run the standard Docker engine and Compose exactly as you would on any Linux machine.

Why run Docker inside a Cube instead of on shared infrastructure?

Cube gives your container host its own kernel and a per-cube sandbox, so your workloads are isolated at the VM level — stronger than sharing a kernel across tenants.

Can I expose a container to the web?

Yes. Map a custom domain with a single CNAME and web traffic gets automatic HTTPS through managed ingress — the Cube itself is never exposed directly.
