Does the secrets-store-csi-driver-provider-gcp support request through proxy

[zeusng-fast]

Question

Does this driver support traffic through proxy?

We install the driver on our local RKE2 (v2.6.7) environment, which is behind company firewall. Traffic to the Internet goes through a proxy server. We modify the deployment file with the following.

...
    spec:
      serviceAccountName: secrets-store-csi-driver-provider-gcp
      containers:
        - name: provider
          image: us-docker.pkg.dev/secretmanager-csi/secrets-store-csi-driver-provider-gcp/plugin@sha256:f7fd197984e95f777557ba9f6daef6c578f49bcddd1080fba0fe8f2c19fffd84
          imagePullPolicy: IfNotPresent
          resources:
            requests:
              cpu: 50m
              memory: 100Mi
            limits:
              cpu: 50m
              memory: 100Mi
          env:
            - name: TARGET_DIR
              value: "/etc/kubernetes/secrets-store-csi-providers"
            - name: http_proxy
              value: "http://my.proxy.ip:port"
            - name: https_proxy
              value: "http://my.proxy.ip:port"
