[markmandel]

Thanks for the submission 🥳 , but I also noticed that we don't have any documentation on this feature in https://agones.dev/site/docs/reference/fleetautoscaler/#webhook-endpoint-specification

Any chance you want to also add them as part of this PR?

[markmandel]

Same things as #4364 - this shouldn't be changed, since this is the current docs that are displayed, and the feature will only move in the next version.

I added a brief description of FleetAutoscaleRequestMetaData.
Should I also add a similar description to the Fleet manifest example and the Wasm Function docs?

Forgot to mention, will need to be feature short coded like so:

https://agones.dev/site/docs/contribute/documentation-editing-contribution/#within-a-page

1.54.0 just released, so the shortcode and version numbers in this PR will also need to be updated.

Thanks!

I’ve added the feature shortcode.

Not sure if the ticket captured everything in:

agones/pkg/util/runtime/features.go

Lines 113 to 121 in e2d3522

	// To promote a feature from alpha->beta:
	// * move from `false` to `true` in `featureDefaults`.
	// * move from `false` to `true` in install/helm/agones/defaultfeaturegates.yaml
	// * remove from `ALPHA_FEATURE_GATES` in build/Makefile
	// * add to `BETA_FEATURE_GATES` in build/Makefile
	// * invert in the e2e-runner config in cloudbuild.yaml
	// * change the value in site/content/en/docs/Guides/feature-stages.md.
	// * add it to test/upgrade/versionMap.yaml
	// * Ensure that the features in each file are organized categorically and alphabetically.

So you also need to do:

agones/cloudbuild.yaml

Lines 309 to 311 in e2d3522

	# Keep in sync with the inverse of 'alpha' and 'beta' features in
	# pkg/util/runtime/features.go:featureDefaults
	featureWithGate="PlayerAllocationFilter=true&FleetAutoscaleRequestMetaData=true&PlayerTracking=true&CountsAndLists=false&RollingUpdateFix=false&PortRanges=false&PortPolicyNone=false&ScheduledAutoscaler=false&GKEAutopilotExtendedDurationPods=false&SidecarContainers=true&WasmAutoscaler=true&Example=true"

But otherwise, this is looking good! Thanks!

This would bring things up to date for what is current, and also move it to beta with the next release 👍🏻

Suggested change

	{{% feature publishVersion="1.54.0" %}}
	{{< beta title="Fleet Metadata in Webhook Requests" gate="FleetAutoscaleRequestMetaData" >}}
	When the `FleetAutoscaleRequestMetaData` feature gate is enabled by default, the Fleet's `labels` and
	`annotations` are included in the `FleetAutoscaleRequest`, allowing webhooks to make scaling decisions based on
	Fleet-specific metadata.
