multus cni binary and configuration not found in the host

What happened?

The spiderpool-agent component runs good, but the multus binary and configuration file not found in the host(/etc/cni/net.d and /opt/cni/bin).
the helm value multus.multusCNI.uninstall was set to be true. And the spiderpool-agent restarts several times.

I tried to reproduce it in my kind environment, but can't do it. It's very strange.

What did you expect to happen?

How to reproduce it (as minimally and precisely as possible)

Additional Context

The spiderpool-agent container has preStop hook to clean up the multus binary and cni configuration:

          preStop:
            exec:
              command:
              - "/bin/sh"
              - "-c"
              - | 
                {{- if .Values.multus.multusCNI.uninstall }}
                rm -f /host/opt/cni/bin/multus || true
                rm -rf /host/etc/cni/net.d/multus.d || true
                rm -f /host/etc/cni/net.d/00-multus.conf || true
                {{- end }}
                {{ .Values.spiderpoolAgent.binName }} shutdown

And the initContainer would install the multus binary and cni configuration.

无法确定如何安装的？但在如下的场景中，将会出现你所提到的问题。

1. 你的集群中，并没有自行安装过 multus
2. 安装 spiderpool 时 --set multus.multusCNI.install=false 指定了 false

~# helm upgrade --install spiderpool spiderpool/spiderpool -n kube-system --version=0.9.2 --set multus.multusCNI.install=false

[root@controller-node-1 bin]# kubectl get po -n kube-system | grep spiderpool
