Vsudd

Vsudd is a daemon that forwards unix domain socket traffic from the host to the guest VM via VSOCK. It can be used to control other daemons, like containerd and dockerd, from the host. An example configuration file is available in examples/vsudd.yml.

After building the example, run the example with linuxkit run hyperkit -vsock-ports 2374 vsudd. This will create a unix domain socket in the state directory that map to the containerd control socket. The socket is called guest.00000946.

If you install the ctr tool on the host you should be able to access the containerd running in the VM:

$ go get -u -ldflags -s github.com/containerd/containerd/cmd/ctr
...
$ ctr -a vsudd-state/guest.00000946 list
ID        IMAGE     PID       STATUS
vsudd               466       RUNNING
