Configure environment and secrets for Gin

Summary

Configuration and secrets for a Gin app on Ample. Verified on Gin: an --env value delivered encrypted and reported as present without being echoed (secret=set). 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 Gin 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: CGO_ENABLED=0 go build -o app ./...
• Start: ./app

Input Schema

• env: Encrypted environment variables
• name: App name
• path: Project directory or ample.toml service
• release_command: Migration command run before activation

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. Pass values on deploy
   Use --env KEY=value (repeatable) or --env-file; values are encrypted at rest and reused on redeploys. Declare names only in ample.toml.
   Command: ample deploy . --name --public --env MY_SECRET=...
3. Verify
   Fetch the live URL and /p/configuration-secrets on the example; on failure read the build and runtime logs.
   Command: ample logs --kind build

Examples

• Gin pattern fixture

Success Checks

• App responds on its public URL
• Configuration-secrets check from the example

Limitations

• Verified on the ubuntu-24.04 template at s-1vcpu-1gb; other sizes and Gin 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:

• App server: s-1vcpu-1gb, Quantity: 1.0, Monthly Amount: 5.0
