Render Web Services

This skill covers Web Service behavior on Render: how traffic reaches your process, how deploys go live, and how optional features (domains, disks, auto-deploy) interact. Use it alongside Blueprint and networking skills when wiring render.yaml or Dashboard settings.

When to Use

• Configuring or debugging port binding, PORT, or multi-port web services
• TLS/HTTPS expectations at the edge vs inside the container
• Health checks blocking or rolling back deploys
• Custom domains, DNS, and certificate provisioning
• Auto-deploy, CI-gated deploys, and PR preview generation
• Persistent disks and their impact on scaling and zero-downtime
• Deploy lifecycle: build, pre-deploy, swap, drain, rollback, shutdown delay

Deeper patterns live under references/ (health checks, domains, deploy phases).
