Hosts
Server inventory with hardware details, status, and provisioning controls

What you see
URL: /hosts (list), /hosts/[id] (detail)
The hosts page is your server inventory. Every bare-metal machine, VM, or cloud instance that PodWarden manages appears here. The list shows key identification and status information for each host.
Fields / columns
| Column | Description |
|---|---|
| Hostname | The machine's hostname as reported by the OS |
| IP address | Primary IP address (Tailscale IP if using mesh networking, otherwise LAN/public IP) |
| Status | Current host state (see status badges below) |
| Cluster | The K3s cluster this host belongs to, if any |
| OS | Operating system name and version |
| CPU | Processor model and core count |
| RAM | Total memory |
| GPU | GPU model and VRAM, if detected |
Available actions
| Action | Where | What it does |
|---|---|---|
| Add host | List page toolbar | Manually register a new host by IP address |
| Discover | List page toolbar | Scan your Tailscale network for new hosts |
| Probe | Host row / Detail page | Connect to the host via SSH and collect hardware information (CPU, RAM, GPU, OS, disk) |
| Provision | Host row / Detail page | Run the Ansible provisioning playbook to install K3s and configure the host |
| Delete | Host row / Detail page | Remove the host from PodWarden's inventory |
| View detail | Click a host row | Opens the host detail page |
Add host modal

Click Add host to manually register a new server. Enter the host's IP address and SSH credentials so PodWarden can connect and probe its hardware.
Host detail page
URL: /hosts/[id]

The detail page shows everything PodWarden knows about a single host, organized into cards:
Hardware details

- CPU -- Model, architecture, core count
- RAM -- Total, used, available
- Disk -- Mount points, total and free space
- GPU -- Model, VRAM, driver version (NVIDIA only)
- Network -- All detected interfaces with IPs
- OS -- Distribution, version, kernel
The hardware card is populated by probing the host via SSH. Hosts with NVIDIA GPUs show an additional GPU table with model, VRAM, and driver version for each card.
Cluster membership
If the host is part of a cluster, the detail page links to the cluster detail and shows the node's role (control-plane or worker).
Provisioning

Click Provision on a host detail page to run the Ansible provisioning playbook. The modal lets you choose between joining an existing cluster or creating a new one.
Status history
A timeline of status changes with timestamps, showing when the host came online, went offline, was probed, or was provisioned.
Status badges
| Badge | Meaning |
|---|---|
| online | Host is reachable via SSH and responding to probes |
| offline | Host is not responding |
| provisioning | Ansible playbook is currently running on this host |
| provisioned | Host has been successfully set up with K3s |
| error | Last probe or provisioning attempt failed |
| unknown | Host has never been probed |
