TryDirect handles server provisioning, Kata setup, +and deployment for you. + +### 1. Create a TryDirect account + +Sign up at [try.direct](https://try.direct) and connect your Hetzner +API token (or use TryDirect's built-in hosting). + +### 2. Create your stack + +From the dashboard, select **OpenClaw** from the app catalog. Choose +**Kata Containers** as the runtime — TryDirect will automatically provision a +Kata-capable server (Hetzner CCX with dedicated CPU and KVM access). + +### 3. Deploy + +Click **Deploy**. TryDirect handles everything: +- Provisions a CCX server with KVM support +- Installs Docker and Kata Containers +- Generates the compose file with `runtime: kata` +- Deploys OpenClaw with hardware isolation + +You get a running OpenClaw instance with Kata isolation in minutes, accessible +via the URL shown in your dashboard. + +### 4. Manage + +Use the TryDirect dashboard or the Stacker CLI: + +```bash +stacker status # container health +stacker logs --service openclaw # view logs +stacker agent status # verify runtime: kata +``` + +> **That's it.** If you don't need full control over the infrastructure, +> TryDirect is the recommended path. Read on only if you prefer to self-host. + +--- + +## Path B: Self-Hosted Setup (Full Control) + +If you'd rather manage your own servers, you can provision and configure +everything yourself using the Terraform and Ansible files included in the +[stacker repository](https://github.com/trydirect/stacker). + +### What You Need + +- A Hetzner Cloud account (or any provider with KVM-capable servers) +- [OpenTofu](https://opentofu.org/) (or Terraform) installed locally +- [Ansible](https://docs.ansible.com/ansible/latest/installation_guide/) installed locally +- The [Stacker CLI](https://github.com/trydirect/stacker) installed + +> **Hetzner users:** You need a **CCX-series** server (dedicated CPU). +> Shared-CPU types (CX, CPX, CAX) don't expose `/dev/kvm` and cannot run Kata. +> See the [Hetzner KVM Guide](../kata/HETZNER_KVM_GUIDE.md) for details. + +### Step 1: Provision a Kata-Ready Server + +The stacker repo includes a ready-to-use Terraform module at +[`docs/kata/terraform/`](../kata/terraform/): + +```bash +# Clone the stacker repo (if you haven't already) +git clone https://github.com/trydirect/stacker.git +cd stacker/docs/kata/terraform + +# Initialize and apply +tofu init +tofu plan \ + -var="hcloud_token=$HCLOUD_TOKEN" \ + -var="ssh_key_name=my-key" \ + -var="server_type=ccx13" \ + -var="location=fsn1" + +tofu apply \ + -var="hcloud_token=$HCLOUD_TOKEN" \ + -var="ssh_key_name=my-key" +``` + +This provisions a Hetzner CCX13 (dedicated-CPU) server with Docker and Kata +pre-installed via cloud-init.
