We have built a custom PHP FPM Docker image for Tokaido. This image ships with a secure and high-performing default configuration with some sane defaults that are generally reasonable for both local development and production environments.
The container is open source, and you can find it here.
Since Tokaido 1.3.0, it has been possible to modify the PHP runtime configuration directly from your .tok/config.yml file. This enables to you ship your Tokaido environment up to Tokaido hosting providers like Ironstar.
In previous versions however, you would do this using environment variables directly against the PHP container spec inside the .tok/config.yml "services" branch. See Directly Managing your docker-compose.tok.yml File for more information on this advanced configuration type.
