description

Configure custom domains for Temps deployments with automatic SSL/TLS certificates via Let's Encrypt. Supports HTTP-01 and DNS-01 challenges, wildcard domains, and Cloudflare DNS integration. Use when the user wants to: (1) Add a custom domain to their Temps app, (2) Set up SSL certificates, (3) Configure DNS for Temps, (4) Add a wildcard domain, (5) Set up HTTPS for their deployment, (6) Configure Cloudflare with Temps. Triggers: "custom domain", "add domain", "ssl certificate", "https setup", "wildcard domain", "dns configuration", "cloudflare temps".

Add Custom Domain

Configure custom domains with automatic SSL/TLS certificates.

Quick Setup

1. Add Domain in Dashboard

1. Go to Project > Settings > Domains
2. Click "Add Domain"
3. Enter your domain (e.g., app.example.com)

2. Configure DNS

Add a CNAME record pointing to your Temps deployment:

Type	Name	Value
CNAME	app	your-project.temps.io

For apex domains (example.com without subdomain), use an A record:

Type	Name	Value
A	@	[Temps IP address]

3. Verify & Get Certificate

Temps automatically:

1. Verifies DNS configuration
2. Provisions Let's Encrypt certificate
3. Enables HTTPS

Challenge Types

HTTP-01 (Default)

Used for standard domains. Temps handles automatically.

Requirements:

• Domain must point to Temps
• Port 80 must be accessible

DNS-01 (Wildcard & Private)

Required for wildcard domains (*.example.com).

Setup with Cloudflare:

1. Add Cloudflare API token in Temps:

   • Go to Settings > DNS Providers
   • Add Cloudflare with Zone API token

2. Add wildcard domain:

   *.example.com
   

3. Temps creates DNS TXT record automatically

Wildcard Domains

For *.example.com to match app.example.com, api.example.com, etc:

1. Requires DNS-01 challenge (HTTP-01 doesn't support wildcards)
2. Requires DNS provider integration (Cloudflare supported)

Cloudflare Setup

1. Create API Token:

   • Go to Cloudflare Dashboard > Profile > API Tokens
   • Create token with "Zone:DNS:Edit" permission
   • Limit to specific zone (your domain)

2. Add to Temps:

   Settings > DNS Providers > Add Cloudflare
   - API Token: [your-token]
   - Zone ID: [from Cloudflare domain overview]
   

3. Add Wildcard Domain:

   *.example.com
   

DNS Records Reference

Subdomain (Recommended)

app.example.com -> CNAME -> your-project.temps.io

Apex Domain

example.com -> A -> [Temps IP]

Or with Cloudflare (CNAME flattening):

example.com -> CNAME -> your-project.temps.io (proxied)

Wildcard

*.example.com -> CNAME -> your-project.temps.io

Certificate Management

Automatic Renewal

Temps automatically renews certificates 30 days before expiration.

Certificate Status

Check certificate status in Dashboard > Domains:

• Pending: DNS verification in progress
• Active: Certificate issued and active
• Expiring: Renewal scheduled
• Failed: Check DNS configuration

Force Renewal

If needed, manually trigger renewal:

1. Go to Domains
2. Click domain
3. Click "Renew Certificate"

Multiple Domains

Add multiple domains to the same project:

app.example.com     -> Production
staging.example.com -> Staging
api.example.com     -> API routes

Each domain gets its own certificate.

Redirects

www to non-www

Add both domains and configure redirect:

1. Add example.com (primary)
2. Add www.example.com (redirect)
3. Set www.example.com to redirect to example.com

HTTP to HTTPS

Automatic - all HTTP requests redirect to HTTPS.

Troubleshooting

DNS not propagating?

• Wait up to 48 hours for propagation
• Check with: dig app.example.com
• Use DNS checker: dnschecker.org

Certificate stuck pending?

• Verify CNAME/A record is correct
• Check no conflicting records exist
• Ensure domain isn't proxied (orange cloud in Cloudflare) during verification

Wildcard not working?

• Requires DNS provider integration
• Verify Cloudflare API token has correct permissions
• Check Zone ID is correct

SSL certificate errors?

• Clear browser cache
• Check certificate in browser: https://app.example.com
• Verify intermediate certificates are served
