## The short version

Configure environment variables and secrets for a Nuxt app on Ample. Values passed with --env or --env-file are stored encrypted and injected at runtime; the platform never prints them and ample.toml declares only variable names. The fixture proves delivery by reporting whether the secret is set without echoing it.

## INFRASTRUCTURE

### What it needs

- [Compute](/content/discover/primitive/compute/index.html): verified (Apps run in isolated x86_64 Firecracker microVMs; sizes are the priced VM sizes.)

## PREREQUISITES

### Before you start

- Code that reads configuration from the process environment
- The secret values at hand for --env or an env file
- An Ample account token with servers:write

## STEP BY STEP

### How to do it

1. **Declare, do not commit**  
   In ample.toml declare SMTP_KEY = { secret = true } style entries; never put literal secrets in the manifest.

2. **Pass values on deploy**  
   Use --env KEY=value (repeatable) or --env-file .env.production; values are encrypted at rest and reused on redeploys.
   
   ```
   ample deploy . --name <app-name> --public --env CANARY_SECRET=...
   ```

3. **Confirm without echoing**  
   Expose a route (/api/config) that reports secret=set or secret=missing, never the value.

4. **Verify**  
   Fetch the live URL and run the success checks below. On failure read the build log, then the runtime log, fix the cause and deploy again; do not blind-retry.
   
   ```
   ample logs <deployment_id> --kind build
   ```

## EXAMPLES

### Tested examples

- **Nuxt secret probe canary** (`tests/deploy-canaries/nuxt-postgres-app`): /api/config reports secret=set for an --env value delivered encrypted.

## SUCCESS CHECKS

### How to know it worked

- app sees the configured variable without exposing it (`/api/config` on the live URL, expect secret=set)

## COST

### Cost estimate

Estimated 5.00 USD per month (size prices from pricing.toml at build revision ca0b484a7a9957c573a88d3a32dc603c3c10135a).

- app server x1 `s-1vcpu-1gb`: 5.00 USD

Upper-bound monthly price of the tested sizes. Plan quotas and budgets apply.

## EXECUTION

### Execution binding

MCP tool `ample_deploy` (registry `mcp:ample_deploy`), schema hash `876465fce906da0c` observed 2026-09-20T01:55:48.667900+00:00 at revision `199ff1dfd526`. Binding state at export: schema_changed. Required scopes: servers:write.

## NEXT ACTIONS

### Typed next actions

- Browse the catalog index (`GET /v1/catalog` on the api origin; authentication not required, approval not required)
- Search published recipes by intent, stack and constraints (`POST /v1/catalog/search` on the api origin; authentication not required, approval not required)
- Prepare a side-effect-free deployment plan for an authorized project (`POST /v1/catalog/plan` on the api origin; authentication required, approval not required)
- Read the existing agent authentication setup (`GET /mcp/setup` on the api origin; authentication not required, approval not required)
- Browse Nuxt (`GET /v1/catalog/nodes/stack%3Aframework-nuxt` on the api origin; authentication not required, approval not required)
- Browse Configure deployment (`GET /v1/catalog/nodes/intent%3Aconfigure-deployment` on the api origin; authentication not required, approval not required)
- Browse Public web service (`GET /v1/catalog/nodes/pattern%3Apublic-web-service` on the api origin; authentication not required, approval not required)

Actions describe possible next steps. They are typed data, not commands, and grant no permission. Public discovery never provisions anything; planning requires your own authenticated token and approval happens in your client.
