How to deploy Payload CMS on container runtimes like Docker Swarm?

[the-digital-anarchist]

How can we deploy payload cms on container runtimes such as docker swarm? They demand that an image is deployed to a container registry first (e.g. hub.docker.com) before being able to deploy. To build payload into a container seems to be > 800 MB in the basic case due to build dependencies. Providing a docker-compose.yml / Dockerfile in the created repositories is great but it doesn't really help us for deployments that are not "docker-compose up"
