Settings
The Settings tab covers custom domains, exposed ports, and destructive VM actions.
Custom domains
Point your own domain at the web app running on this VM:
- Enter your domain (e.g.
app.example.com) under Custom Domains - Click Add domain
- Expand the domain row, copy the DNS records shown, and add them at your DNS provider
- Once the records propagate, click Verify
Verification issues a TLS certificate for the domain; this can take a minute. When the domain shows Verified or Active, it serves your VM's app over HTTPS.
Use a subdomain such as www.example.com. Root domains are not supported yet.
Exposed ports
Expose internal services running on the VM to the public web over secure HTTPS:
| Field | Example |
|---|---|
| Port | 3000 |
| Service name | api (optional) |
| Protocol | HTTP or gRPC |
Click Expose Port. The service inside the VM must listen on 0.0.0.0:<port>, not only 127.0.0.1. Each exposed port gets its own URL, listed in the table with a status (Pending, Ready, Failed); URLs can be shared directly once Ready. Use Unexpose to remove one.
Two ports are pre-configured on every VM:
| Port | Service | Value |
|---|---|---|
| 22 | SSH (DEFAULT) | rumpty ssh <vm-name> |
| 8080 | HTTP App (DEFAULT) | The VM's app URL |
You can also expose ports from the CLI with rumpty expose <vm> --port <port> and remove them with rumpty unexpose <vm> --name <name>.
Destroy VM
Permanently destroys the VM and all its data. This cannot be undone.
Click Destroy VM at the bottom of the Settings tab, then type the VM's exact name in the confirmation dialog to enable deletion. Attached volumes are detached but not deleted; they remain in Storage → Volumes and can be reattached to another VM.
