shutdown manager image not possible to override from envoyproxy/gateway-dev

[zetaab]

Description:

What issue is being seen? Describe what should be happening instead of
the bug, for example: Envoy should not crash, the expected value isn't
returned, etc.

I am trying to develop EG and building own gateway controller. However, when I try to start own gateways it will use always envoyproxy/gateway-dev prefix images as shutdown image. It is not possible to override shutdown image as own image. Which makes it really difficult to develop envoy gateway. This shutdown image is defined in

gateway/internal/infrastructure/kubernetes/proxy/resource.go

Lines 279 to 284 in 3f8d05b

	func expectedShutdownManagerImage() string {
	if v := version.Get().ShutdownManagerVersion; v != "" {
	return fmt.Sprintf("%s:%s", strings.Split(egv1a1.DefaultShutdownManagerImage, ":")[0], v)
	}
	return egv1a1.DefaultShutdownManagerImage
	}

and as you can see, its not possible to override that value.

Repro steps:

Include sample requests, environment, etc. All data and inputs
required to reproduce the bug.

1. build own envoy gateway controller image GOARCH=amd64 IMAGE=jesseh/envoy-gateway make image
2. deploy controller with custom image
3. create new gateway

envoy-eg-internal-7f4ff7e4-5874dd88d9-pprgg   1/2     ImagePullBackOff   0          17m
envoy-eg-internal-7f4ff7e4-7dc49f9c4f-zxhcx   1/2     ImagePullBackOff   0          4m47s
envoy-eg-internal-7f4ff7e4-d9d76b974-p6746    1/2     ImagePullBackOff   0          10m

events:

  Normal   BackOff    3m34s (x6 over 4m56s)  kubelet            Back-off pulling image "envoyproxy/gateway-dev:3f8d05b3"
  Warning  Failed     3m34s (x6 over 4m56s)  kubelet            Error: ImagePullBackOff
  Normal   Pulling    3m22s (x4 over 4m58s)  kubelet            Pulling image "envoyproxy/gateway-dev:3f8d05b3"

in this case the correct image is available in jesseh/gateway-dev:3f8d05b3, but its not possible to override the image in anyway

Note: If there are privacy concerns, sanitize the data prior to
sharing.

Environment:

Include the environment like gateway version, envoy version and so on.

current main branch

Logs:

Include the access logs and the Envoy logs.

I manually now modified https://github.com/envoyproxy/gateway/blob/main/api/v1alpha1/shared_types.go#L30 row to jesseh/gateway-dev:latest and everything works fine after new compilation. However, this is not really developer friendly currently

seems that there is PR #3269 for this already
