Configure build and start for Echo

Summary

Build and start for a Echo app on Ample. Verified on Echo: the app built and started with the documented commands and answered on its public HTTPS URL. Build and start: CGO_ENABLED=0 go build -o app ./... then ./app on the ubuntu-24.04 template (go.sum committed for a reproducible build).

Prerequisites

• A Echo project (CGO_ENABLED=0 go build -o app ./... then ./app on the ubuntu-24.04 template (go.sum committed for a reproducible build))
• An Ample account token with servers:write

Tested Configuration

• Template: ubuntu-24.04
• Runtime: go
• Size: s-1vcpu-1gb
• Build Command: CGO_ENABLED=0 go build -o app ./...
• Start Command: ./app

Workflow Steps

1. Build and start
   CGO_ENABLED=0 go build -o app ./... then ./app on the ubuntu-24.04 template (go.sum committed for a reproducible build); the server must bind 0.0.0.0 on PORT.
2. Deploy
   Run the synchronous deploy once and read the result.
   Command: ample deploy . --name --public
3. Verify
   Fetch the live URL on the example; on failure read the build and runtime logs.
   Command: ample logs --kind build

Success Checks

• Description: app responds on its public URL
  Kind: http_get
  Path: /
  Expect: ample canary echo patterns

Limitations

• Verified on the ubuntu-24.04 template at s-1vcpu-1gb; other sizes and Echo major versions are not verified.
• Region, compliance attestations and request-duration limits are unknown and not claimed.

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
