steveej | is anyone here interested in rootless nixos-containers? | 10:04:27 |
ElvishJerricco | steveej: I definitely would be | 10:05:26 |
ElvishJerricco | oh, wait a sec, from systemd-nspawn's man page section on unprivileged operation:
Only disk image based containers are supported (i.e. --image=). Directory based ones (i.e. --directory=) are not supported.
When running in unprivileged mode, some needed functionality is provided via systemd-mountfsd.service(8) and systemd-nsresourced.service(8).
that sucks
| 10:07:20 |
ElvishJerricco | and it's really weird because you wouldn't need mountfsd (and the authentication craziness it entails) if you did directory based containers | 10:10:22 |
steveej | maybe the systemd folks are open to implementing the gap. i'd be surprised as there doesn't seem to be much demand for systemd-nspawn in general | 10:14:53 |
ElvishJerricco | systemd-nspawn and systemd-vmspawn were designed first and foremost as tools to test an OS with, not so much a proper containerization / virtualization framework | 10:16:16 |
ElvishJerricco | of course nspawn has evolved a lot since | 10:16:37 |
ElvishJerricco | But yea I don't really understand why directory based nspawn isn't possible unprivileged. That really does seem like the easier thing to do unprivileged | 10:17:46 |
ElvishJerricco | so I bet it just wasn't the priority of whoever implemented unprivileged operation so they didn't do it | 10:18:08 |
magic_rb | Wouldnt it be better to just use runc for this? I do use nspawn but like, runc exists | 10:18:48 |
ElvishJerricco | well, if you wanna rewrite the nixos containers system with runc then be my guest :) | 10:19:42 |
magic_rb | :) might try tbh, when i finish my bachelor. I do kind of want a better system which would be declarative but not really. (Split the eval into parts but make sure everything updates in tandem) | 10:20:46 |
steveej | i'm up for integrating a rust-based container runtime with nixos-containers, just in case i had to change something about it. | 10:21:14 |
