Hello, We have our application packaged in a discoverable GPT partition image and typically boot it using systemd-nspawn. We’re now exploring how to deploy multiple instances of this application in the cloud and are looking for orchestration options. Note that our application is not fitting docker …

Hi, What you need might be possible but it’s not necessarily supported - it’s uncharted territory and you’d be basically on your own. You cannot override the init that Fly machines boot with; we inject a custom init process that then spawns a few other processes, notably the Dockerfile’s ENTRYPOIN…

@utezduyar , as @wjordan mentioned in System has not been booted with systemd as init system (PID 1). Can't operate. - #3 by wjordan , you can start systemd in its own namespace using unshare : CMD ["unshare", "--pid", "--fork", "--mount-proc", "/lib/systemd/systemd"] Then you can use nsenter to ente…

Thank you both for your time and response. I think using a tool that is not meant to be is going to bite me back in the future. However, let me take this opportunity and discuss with you (fly) about business opportunities with a technical propose. The reason why we use nspawn is because we use the …

Thank you all again. Would fly like to help me go through the process (requesting access to Pilot based machine), APIs etc so we give this setup a whirl and hopefully write a blog on fly.io called “how to start root fs packed as Discoverable GPT” with it’s current state?

My understanding is that we have quietly enabled Pilot for everyone. If your use the machine API and you include containers in your request per the blog post I linked, you should be able to run systemd as pid 1. If this is not the case, let me know and I’ll find out more. As to the rest, I’ll be …

Creating an app using machine API is kinda complicated. I opened Fly Machines API and felt perplexed. Is there a simple tutorial or an example of how to get started with Machines API? And I don’t understand should we do some extra steps for systemd to work as PID 1 or would it work automatically r…

systemd should work as PID 1 mathematically is you specify containers. I plan to look into some usability enhancements for working with containers this week - if you can tell me a bit more about what you are trying to accomplish, that would both be helpful to me and would enable me to provide more …

thanks, I appreciate your help. eventually I figured out how to create an app using API. I looked here: Machines · Fly Docs and created a simple example app: curl -i -X POST \ -H "Authorization: Bearer ${FLY_API_TOKEN}" -H "Content-Type: application/json" \ "${FLY_API_HOSTNAME}/v1/apps/my-tes…

Have you tried the --container parameter on fly ssh console ?

Deploying root file system applications

Our containers should support running applications as PID 1. Perhaps that would work here?
