Render CLI Basics
Install and use the Render CLI to inspect and manage services.
bash
brew install render # Install CLI (macOS)render login # Authenticaterender services # List services in your workspacerender deploys create <service-id> # Trigger a new deployrender logs <service-id> --tail # Stream live logsrender ssh <service-id> # SSH into a running instance (paid plans)render psql <database-id> # Open a psql shell to a Render Postgres DB
render.yaml Blueprint
Define infrastructure as code for multi-service apps.
yaml
services: - type: web name: my-api env: node plan: free buildCommand: npm install && npm run build startCommand: npm start envVars: - key: NODE_ENV value: production - key: DATABASE_URL fromDatabase: name: my-db property: connectionStringdatabases: - name: my-db plan: free databaseName: myapp user: myapp_user
Health Check Endpoint
Expose a route Render polls to verify your service is alive.
javascript
// Express example — configure the path in the dashboard// or render.yaml as `healthCheckPath: /healthz`app.get('/healthz', (req, res) => { res.status(200).send('ok');});
Core Concepts
Key Render service types and deployment behavior.
- Web Service- long-running process bound to a port, auto-deployed on git push
- Static Site- prebuilt frontend assets served from Render's global CDN, free SSL included
- Background Worker- runs continuously with no exposed HTTP port, ideal for queue consumers
- Cron Job- runs a command on a schedule defined by a standard cron expression
- Private Service- reachable only from other services in the same Render private network
- Environment Groups- shared sets of env vars that can be linked across multiple services
- Zero-downtime deploys- new instance is health-checked before traffic is switched over on paid plans
Pro Tip
Free-tier web services on Render spin down after 15 minutes of inactivity and take ~30-60 seconds to cold-start on the next request — use a paid instance type or an external uptime pinger if you need consistently fast response times.
