well, at least they had the courtesy of using "-f" in their curl-to-sh https://github.com/basecamp/kamal/blob/v1.0.0/lib/kamal/comm...

Honestly these days I am leaning towards this approach: https://github.com/mrsked/mrsk/ It's all just docker.

Did you consider MRSK[1], k3s[2], or dokku[3]? They are all significantly simpler to operate than Kubernetes, curious to hear your take. On logs, I agree and have looked for the same. A simple way to aggregate logs in one machine, heck it could even be running SQLite, and query via a web UI. Doesn't seem to exist for this scale.

I don't think there's a writeup out there, but mrsk just uses docker under the hood. So, if you have a CMD in your Dockerfile, it will use that. If you have an image that can run multiple things, like a rails app that can run the app process for web traffic by default, but it can also run job workers with the right command, you can provide the cmd in the mrsk config. You can see this in the jobs role in the example: https://github.com/mrsked/mrsk#using-different-roles-for-ser....

> When you look at the issues: https://github.com/mrsked/mrsk/issues/44 Wow. That’s uh, that’s certainly a decision. > They're the same service, because they're running the same image If something purports to “run my containers” and “be an alternative to K8s”, I’d kind of expect it to run whatever it’s told. Whether running identical containers on the same host is a good thing or not really depends on your architectures choices and trade offs. Blindly being like “you can’t have this because reasons” makes this whole tool a giant non-starter IMO.

I may be ignorant but doesn't that scenario you described encapsulate how MRSK functions? From the MRSK readme[1]: Connect to the servers over SSH (using root by default, authenticated by your ssh key) Install Docker on any server that might be missing it (using apt-get) Log into the registry both locally and remotely Build the image using the standard Dockerfile in the root of the application. Push the image to the registry. Pull the image from the registry onto the servers. Ensure Traefik is running and accepting traffic on port 80. Ensure your app responds with 200 OK to GET /up. Start a new container with the version of the app that matches the current git version hash. Stop the old container running the previous version of the app. Prune unused images and stopped containers to ensure server

something to note DHH is a beast. MSRK seems most of MSRK was written by him alone - https://github.com/mrsked/mrsk/commits/main?after=83dc82661b... his output is crazy. that's why he gets the big bucks

Such a terrible idea, let's build something that everyone else has a solution for, we're on our own with our custom solutions that no one else know or use. We'll see how many years it will take them to come back to Kubernetes or equivalent. And the argument k8s is too complicated so build our own looks really bad from an engineering perspective. When you look at the issues: https://github.com/mrsked/mrsk/issues/44 you can some see trivial shortcoming that has been solved for years by other solutions.

I'm not sure if anyone other than 37Signals is using it at scale yet, so you may get a better idea by looking at the docs yourself. https://github.com/mrsked/mrsk

The intro from README explains it well: ”MRSK deploys web apps anywhere from bare metal to cloud VMs using Docker with zero downtime. It uses the dynamic reverse-proxy Traefik to hold requests while the new application container is started and the old one is stopped.” https://github.com/mrsked/mrsk I’m looking forward testing this out. I already use Traefik and back in the day I used to use Capistrano to deploy Django apps, it feels like closing the circle :)

This is mrsk: https://github.com/mrsked/mrsk It is described as "Capistrano for containers" (This is DHH/37signals so we are in the ruby world) Mrsk is written in ruby and it is hard to type because autocorrect will change it to the name of a certain billionaire
