WIP: Add frakti to run kubernetes pods in KVM #21966

moretea · 2017-01-18T10:51:33Z

Motivation for this change

Frakti uses hyperd to start the different containers that live in one pod in a KVM vm.
This offers better isolation.

Things done

Tested using sandboxing
(nix.useSandbox on NixOS,
or option build-use-sandbox in nix.conf
on non-NixOS)
Built on platform(s)
- NixOS
- macOS
- Linux
Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
Tested execution of all binary files (usually in ./result/bin/)
Fits CONTRIBUTING.md.

At this moment, I'm not able to build hyperd, and have no clue how to fix this.
It tries to build (part of?) docker and fails with the following error message:

/cc @offlinehacker @tailhook (since you're the maintainers of Docker). Do you know what's going wrong here?

offlinehacker · 2017-01-18T11:09:37Z

Try deleting all the vendor folders of the vendor folders, this is usually an issue.

+      listenStreams = [ "/run/libvirt/virtlockd-sock" ];
+    };
+
+    systemd.services.virtlockd = {


had to comment this out because it conflicts with libvirtd, maybe libvirtd just needs to be a dependency for this?

The exact error is error: The unique option systemd.services.virtlockd.description' is defined multiple times, in /etc/nixos/nixpkgs/nixos/modules/virtualisation/libvirtd.nix' and /etc/nixos/nixpkgs/nixos/modules/virtualisation/hyperd.nix'.` for reference

This should be /var/run/hyperd.sock

I got the same error.

I guess this redefines a service that already exists

I added Hypervisor = libvirt here, but I guess this should be a config option

I got it working with kvm actually.

I added

To get this to start

indeed, added those myself as well 👍

I had to remove the @ symbol here, not sure what it does but with it in place, I'd get an error saying logtostrerr is not in $PATH, removing that option would cause -v=0 not in path etc

edude03 · 2017-07-08T15:34:22Z

In the end I've yet to get it to work, hyperctl is unable to connect to the daemon, I'm still trying to figure that out

I guess we have a remove-references feature for this (should be easy to find). If it is not applicable, please elaborate in the code.

Use {} syntax to combine both lines into one.

Going in the right direction, and I like that there are tests from the beginning.

I have made some more progress locally as well. Will merge these charges and push an update today.

edude03 · 2017-07-11T15:14:04Z

@moretea I'm super excited to see the updated PR :D

edude03 · 2017-08-15T17:14:12Z

@moretea are you still cranking along on this?

offlinehacker · 2017-09-23T18:52:03Z

Have you tried this with #25426

bachp · 2017-09-23T19:07:24Z

@moretea I have a nix derivation for runv and hyperstart that I'm trying to get workingas an alterantive docker runtime. I think especially hyperstart might be useful to provide a default kernel and initrd. If you are interested I will push my WIP branch next time I'm at my dev machine.

moretea · 2017-09-23T19:11:03Z
