Kubelet root directory fix
Kubelet ignores the root-dir argument and creates the socket at:
/var/lib/kubelet/device-plugins/=kubelet.sock
https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/#device-plugin-implementation
Therefore, we mount /var/lib/kubelet to the BOSH data directory and keep it unchanged.
This is the only way I've found to make the CSI plugins work.
Switch to Using
network.targetin SystemdAn error in my deployment indicated that the systemd unit
sys-subsystem-net-devices-eth0.devicedoes not exist. In systemd, network devices are not always available as.deviceunits. Instead, you can use a more general dependency likenetwork.target, which ensures that network services are available. This change allows the service to start once the network is properly configured, without relying on a specific device unit that may not be present.Other Changes
I introduced the
k3s-utilspackage to share functions between the server and agent jobs (DRY) and cleaned up the ERB code.
