Build & Start Commands

Configure your install, build, and start commands in service settings. Here are common examples:

Node.js / Bun
Build Command:  npm run build
Start Command:  npm start
Python

Environment Variables

Set environment variables in the Settings tab. They're encrypted at rest and available during build and runtime. See the Environment Variables guide for details.

Health Checks

HostStack checks your service is healthy before routing traffic. Set a health check path (e.g., /health) in your service settings.

yaml
healthcheck:
  path: /health
  interval: 10s
  timeout: 5s
  retries: 3
