FAQPage Schema
How do I deploy a Rails app to Hetzner Cloud using Kamal?▼

To deploy a Rails app to Hetzner Cloud using Kamal, you need to provision the server, configure firewalls, and manage secrets via .env and .kamal/secrets. This process automates deployment while integrating Cloudflare for DNS and SSL management.

How does Kamal handle Cloudflare DNS and SSL certificates for Rails deployments?▼

Kamal integrates with Cloudflare to manage DNS routing and SSL certificate issuance automatically during Rails deployment. This integration ensures secure connections and resolves common SSL certificate provisioning issues on Hetzner Cloud.

Can I use Kamal to deploy a Rails 8 application with Inertia.js to production?▼

Yes, you can deploy Rails 8 with Inertia.js to production using Kamal on Hetzner Cloud. The deployment process supports configuring production environments, including setting up Cloudflare domains and configuring production email.

Why does my Kamal deployment to Hetzner fail with SSL certificate or container errors?▼

Kamal deployment failures on Hetzner often stem from SSL certificate issuance or container crashes. You can troubleshoot these issues by checking Cloudflare DNS propagation, verifying .kamal/secrets, and reviewing deploy lock states.

Do I need Docker to manage secrets and environment variables for Kamal deployments?▼

You manage secrets and environment variables for Kamal deployments using .env and .kamal/secrets files rather than Docker directly. Docker containerizes the Rails application, while Kamal handles injecting these configurations during deployment.

What is the best way to configure Hetzner firewalls for a Rails production server?▼

Configuring Hetzner firewalls for a Rails production server involves setting rules to allow traffic on necessary ports while restricting external access to internal services. This setup is automated during the initial server provisioning phase.
