Custom Domains Guide - Elk Documentation

1. Domain Configuration

To add a custom domain to your Elk application, follow these steps:

elk domains add example.com --app your-app-name

This command will automatically provision an SSL certificate via Let's Encrypt.

Update your domain's DNS records to point to Elk:

Elk will verify domain ownership via DNS TXT record. You'll see a prompt like:

Please add this TXT record to verify ownership:
Name: _acme_challenge.example.com
Value: 4jI9aX32tL8vqRF7GZmL4x7sD6v3k8m

elk domains enforce-https example.com --app your-app-name

This will redirect all HTTP requests to the HTTPS version of your domain.

Wildcard domain support is available for enterprise plans. To configure:

elk domains add *.example.com --app your-app-name

*.example.com → 192.0.2.1
