What's using DBUS?

[leseb]

Hi,

I noticed /var/run/dbus was mounted here https://github.com/kata-containers/kata-containers/blob/main/tools/packaging/kata-deploy/kata-deploy/base/kata-deploy.yaml#L57-L59.

Which component is using DBUS to communicate? I could find anything in the architecture design docs, the code showed me this

kata-containers/src/runtime/pkg/resourcecontrol/utils_linux.go

Line 95 in a67402c

func createCgroupsSystemd(slice string, unit string, pid int) error {

.

Can someone elaborate?

Thanks in advance.

@leseb, Kata Deploy is a daemonset used to deploy Kata Containers on a node.
When we deploy Kata Containers, we also change the containerd engine (containerd or CRI-O) configuration, and end up having to call systemctl restart ${container_engine}, and we have to have dbus there in order to use system, from our daemonset image.

I hope that helps.

Yes, it does, thanks!
