render-web-services

What problem does it solve?

Configures Render web services—port binding, TLS, health checks, custom domains, auto-deploy, PR previews, persistent disks, and deploy lifecycle. Use it to set up a web service, fix health check failures, add a custom domain, configure zero-downtime deploys, or troubleshoot port binding issues.

Core Features & Use Cases

• Port binding: listen on 0.0.0.0 and use the PORT environment variable Render provides.
• TLS/HTTPS: TLS terminates at Render's edge; understand when to terminate inside the app.
• Health checks and deploy lifecycle: configure healthCheckPath, prevent failed deploys from going live, and manage pre-deploy, swap, and rollback.
• Custom domains: domain provisioning, DNS guidance, apex and wildcard handling, and auto-renewing TLS.
• Auto-deploy and PR previews: control deployments via autoDeployTrigger and enable PR previews for previews environments.
• Persistent disks: effects on scaling and zero-downtime deploys, with caveats about disks.
• Deploy lifecycle: build, pre-deploy, deploy, drain, and rollback flows.

Quick Start

Create a new Web Service in Render and validate port binding, TLS, and health checks using the Dashboard.
