What are the available values for webhookTemplate?

[kenske]

Couldn't find a list of available template placeholders for the webhook template, except for the example in the helm docs:

{"text":"[NTH][Instance Interruption] EventID: {{ .EventID }} - Kind: {{ .Kind }} - Instance: {{ .InstanceID }} - Node: {{ .NodeName }} - Description: {{ .Description }} - Start Time: {{ .StartTime }}"}).

Is there a list somewhere with all the available placeholders? I'm trying to figure out if there's a way to get the cluster name.

The object used to fill in the template is InterruptionEvent, so any field in that struct is available for the webhook message:

aws-node-termination-handler/pkg/monitor/types.go

Lines 41 to 61 in 62a9142

	// InterruptionEvent gives more context of the interruption event
	type InterruptionEvent struct {
	EventID string
	Kind string
	Monitor string
	Description string
	State string
	AutoScalingGroupName string
	NodeName string
	NodeLabels map[string]string
	Pods []string
	InstanceID string
	ProviderID string
	IsManaged bool
	StartTime time.Time
	EndTime time.Time
	NodeProcessed bool
	InProgress bool
	PreDrainTask DrainTask `json:"-"`
	PostDrainTask DrainTask `json:"-"`
	}

Unfortunately, cluster name is not currently one of those fields.
