Domains & SSL

Your free .dockhosting.dev subdomain, and adding a custom domain with an auto-renewing certificate.

The free subdomain

Every project is live on a your-app.dockhosting.dev subdomain the moment it deploys successfully — HTTPS included, nothing to configure.

Adding your own domain

  1. In your project's Domains settings, add the domain (or subdomain) you want to use.
  2. Point its DNS at DockHosting the way the dashboard shows — typically a CNAME for a subdomain, or the records shown for an apex domain.
  3. Once DNS resolves, DockHosting issues a certificate automatically. This usually takes a few minutes, occasionally longer depending on DNS propagation.

Renewal

Certificates renew themselves before they expire. There's nothing to schedule or remember — if a certificate is ever showing as expired, it means DNS has stopped pointing at DockHosting, not that renewal failed silently.

How many domains

Custom domains are plan-limited — see Pricing & billing for the exact count per plan. The free subdomain doesn't count against that limit.

Troubleshooting a domain that won't issue a certificate

  • Confirm DNS actually resolves to DockHosting — a dig or nslookup on the domain should show the record you were given, not your previous host
  • If you recently changed DNS, allow time for propagation before assuming something is broken
  • A domain still pointed at a different provider (an old CNAME, a parking page) will never pass the ownership check certificate issuance requires

Private networking

Why your app and database should talk over the private network, not the public internet.

Scale to zero

Idle apps sleep at 0 CPU and RAM, and wake on the first request.
