# Deploy Ruby on Tensel

Connect a GitHub repo and push. The rest is handled. No DevOps required.

From commit to production

```
$ tensel github import acme/ruby-appDetected Ruby — building with Nixpacks.→ build  isolated context, Paris→ rollout  1/1 replicas  healthy ✓ https://ruby-app.tensel.cloud   38 s
```

## How Ruby is detected

Detection

a `Gemfile` at the build root

Runs as

a Ruby application (Rails, Sinatra…) in a serverless container in Paris

## From repo to URL

1. 1
   Import the repository — “tensel github import” or the dashboard — or drop a folder, no git required.
2. 2
   Tensel detects Ruby, builds in a disposable virtual machine and publishes an immutable image.
3. 3
   Your application answers over HTTPS on its tensel.cloud subdomain; every later push redeploys.

## Good to know

- The build runs under Nixpacks. If it picks the wrong start command, set your own in the build settings (tensel builds set); the resolved default stays visible next to your override.
- Your app must listen on the port the platform provides (PORT). Every framework's production server does this by default.
- Environments scale to zero on the Free plan; always-on keeps an instance resident from the Personal plan up.
