Allow applications to be deployed without needing to set up a repository in a remote Docker registry. If the registry server starts with `localhost`, Kamal will start a local docker registry on that port and push the app image to it. Then when pulling the image onto the servers, we use net-ssh to forward the that port from the app server to the deployment server. This will allow the deployment server to pull the image from the registry as if it were local, meaning we don't need to set up a cert.
Kamal: Deploy web apps anywhere
From bare metal to cloud VMs, deploy web apps anywhere with zero downtime. Kamal uses kamal-proxy to seamlessly switch requests between containers. Works seamlessly across multiple servers, using SSHKit to execute commands. Originally built for Rails apps, Kamal will work with any type of web app that can be containerized with Docker.
