# Configure S3-compatible access for Astro

## Summary
Object storage client for an Astro app on Ample. Verified on Astro: bucket credentials delivered as encrypted S3_* environment variables and a validated PutObject/GetObject round-trip linked to a database row (upload=ok linked=ok). Build and start: astro build with the @astrojs/node standalone adapter then node ./dist/server/entry.mjs on the node-22 template.

## Representative Queries
- Configure S3-compatible access for Astro
- Where can I host Configure S3-compatible access built with Astro?
- I need exact S3 endpoint, credentials, operation requirements and an upload/download verification.

## Resource Requirements
- primitive:compute
- primitive:s3-compatible-object-storage

## Infrastructure Requirements
1. **Compute**  
   Status: Verified  
   Summary: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.

2. **S3-compatible object storage**  
   Status: Verified  
   Summary: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

## Prerequisites
- A Astro project (astro build with the @astrojs/node standalone adapter then node ./dist/server/entry.mjs on the node-22 template)
- A bucket from `ample bucket create` with credentials passed as encrypted S3_* environment variables
- An Ample account token with servers:write, buckets:read

## Steps
### Build and start  
astro build with the @astrojs/node standalone adapter then node ./dist/server/entry.mjs on the node-22 template; the server must bind 0.0.0.0 on PORT.

### Create the bucket and pass its credentials  
Create it once with `ample bucket create`, then pass endpoint, region, bucket and keys with --env; use path-style addressing.  
Command:  
`ample deploy . --name  --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...`

### Verify  
Fetch the live URL and /p/browser-file-uploads on the example; on failure read the build and runtime logs.  
Command:  
`ample logs  --kind build`

## Examples
### Astro pattern fixture  
Verified object storage client on Astro.  
Source Ref: tests/deploy-canaries/astro-patterns

## Success Checks
1. **App responds on its public URL**  
   Kind: http_get  
   Path: /  
   Expect: ample canary astro patterns
2. **Browser-file-uploads check from the example**  
   Kind: http_get  
   Path: /p/browser-file-uploads  
   Expect: see the pattern fixture checks

## Limitations
- Verified on the node-22 template at s-1vcpu-1gb; other sizes and Astro major versions are not verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- PutObject and GetObject with path-style addressing are verified; other S3 operations are not.

## Cost Estimate
- Currency: USD  
- Monthly Amount: 5.0  
- Basis: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty  
- Components:  
  - Name: app server  
    Size: s-1vcpu-1gb  
    Quantity: 1.0  
    Monthly Amount: 5.0  
- Note: Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.

## Evidence Summary
- Kind: canary_run  
  Summary: Astro pattern fixture deployed on Ample; for this guide: bucket credentials delivered as encrypted S3_* environment variables and a validated PutObject/GetObject round-trip linked to a database row (upload=ok linked=ok).
