Build and Deploy a .NET Crypto Price Ticker with Redis

Build a .NET Minimal API that polls a public crypto price feed, stores a compact latest-price buffer in Redis, and serves a realtime dashboard endpoint.

The Stack

• .NET 8 Minimal APIs
• Redis for latest prices and short-lived buffers
• Adios runtime for Linux-based deployment without IIS or Azure setup

Why This Architecture Fits the Workload

A .NET Minimal API can run as a Linux service without an IIS-specific deployment path. The application keeps its Redis connection and polling loop in source, while Adios supplies the runtime, route, TLS, logs, and secret references.

1. Build the API

Ask the Adios AI agent:

Build a .NET 8 Minimal API crypto ticker. Poll a public crypto price endpoint,
store latest prices in Redis, expose GET /prices and /healthz, and add a simple
HTML dashboard.

2. Add adios.yaml

name: dotnet-crypto-ticker
region: de
replicas: 1

build_cmd: dotnet publish -c Release -o /app/out
start_cmd: dotnet /app/out/CryptoTicker.dll

runtime:
  name: dotnet@8.0
  port: 8080
  health_path: /healthz
  memory_mb: 768

secrets:
  REDIS_URL: secret://REDIS_URL

requires:
  - cache

3. Deploy

adios up
adios logs --runtime

4. Verify

Open /prices, refresh the dashboard, and check the runtime logs while prices update. Redis keeps the latest values close to the app without putting every request through the external API.

Review the .NET deployment path, the Redis deployment checks, or the complete .NET 8 template before adapting this example.
