I’m currently working on Meridian, a deployment tool similar to Kamal, but built around rootless Podman instead of Docker.
You don’t necessarily need a container registry either, since Meridian can also transfer and deploy images directly over SSH.
It uses kamal-proxy and supports blue-green deployments. It can also build and serve fingerprinted static assets from a separate subdomain as part of the deployment, so you don’t need a CDN.
I’m already using Meridian for some of my own projects. There is no 0.1.0 release yet, even though some text might read like there is a release, but I’m getting closer.
