How can I change port for shutdown manager(8090)

[Sinamcp]

What question do you have?:
I deployed 3 envoy on the same edge node, with different ingressclass and hostnetwork: true. I just wanted to know how can I change the shutdown port for each envoy, I mean what the port name is?
For example for liveness porbe is metrics.

Environment:

• Contour version: 1.25
• Kubernetes version: 1.23

See https://projectcontour.io/docs/1.25/redeploy-envoy/#shutdown-manager-config-options. You can provide the --serve-port flag to the contour envoy shutdown-manager command (https://github.com/projectcontour/contour/blob/main/examples/contour/03-envoy.yaml#L27-L31), and then change the corresponding port in the preStop hook (ref. https://github.com/projectcontour/contour/blob/main/examples/contour/03-envoy.yaml#L95).

Thanks @skriss

      containers:
        - args:
            - envoy
            - "shutdown-manager --serve-port=8091"
          command:
            - contour
          image: 'ghcr.io/projectcontour/contour:v1.25.0'
          imagePullPolicy: IfNotPresent
          lifecycle:
            preStop:
              exec:
                command:
                  - contour
                  - envoy
                  - shutdown
          name: shutdown-manager
          volumeMounts:
            - mountPath: /admin
              name: envoy-admin

is that ok? but it said  contour: error: expected command but got "shutdown-manager --serve-port=8091", try --help

Put --serve-port=8091 on a new line within args
