You can deploy a Rails application to production with zero downtime by using Kamal to orchestrate Docker containers, running rolling restarts and health checks to switch traffic without dropping active requests.

The best way to manage environment secrets and SSL certificates during a Rails Docker deployment is to use Kamal to configure environment variables and automate SSL/TLS setup across your production servers.

Database migrations during a zero-downtime Kamal deployment run as a distinct step in the process, ensuring schema changes are applied safely before the new Docker containers take over production traffic.

Yes, you can use Kamal to deploy a Rails app across multiple servers, leveraging its multi-server orchestration to run automated health checks and rolling restarts for reliable production configurations.

If a Rails deployment fails, you can execute a rollback procedure with Kamal to revert to the previous working Docker container version, ensuring predictable recovery and minimizing production downtime.

Yes, you need Docker to handle environment management and zero-downtime deployments for Rails, as Kamal relies on Docker-based infrastructure to containerize the app and manage multi-server orchestration.
