get triggerName in template

[dexter-hwang]

Summary

I'm configuring a webhook-forwarder layer for multiple sources and multiple targets.

so, I made all triggers use same template like this.

  template.app-common: |
    webhook:
      forwarder:
        method: POST
        body: |-
          {
            "app": {
              "metadata": {
                "name": "{{.app.metadata.name}}"
              },
              "status": {
                "health": {
                  "status": "{{.app.status.health.status}}"
                },
                "operationState": {
                  "operation": {
                    "sync": {
                      "revision": "{{.app.status.operationState.operation.sync.revision}}"
                    }
                  },
                  "finishedAt": "{{.app.status.operationState.finishedAt}}",
                  "message": "{{.app.status.operationState.message}}",
                  "phase": "{{.app.status.operationState.phase}}"
                },
                "sync": {
                  "status": "{{.app.status.sync.status}}",
                  "revision": "{{.app.status.sync.revision}}"
                },
                "conditions": [
                  {{range $index, $c := .app.status.conditions}}
                  {{if ne $index 0}},{{end}}
                  {
                    "type": "{{$c.type}}",
                    "message": "{{$c.message}}"
                  }
                  {{end}}
                ]
              }
            },
            "context": {
              "argocdUrl": "{{.context.argocdUrl}}"
            }
          }
  trigger.on-deployed:  |
    - when: app.status.operationState.phase in ['Succeeded'] and app.status.health.status == 'Healthy'
      oncePer: app.status.sync.revision
      send: [app-common]
  trigger.on-health-degraded: |
    - when: app.status.health.status == 'Degraded'
      send: [app-common]
  trigger.on-sync-failed: |
    - when: app.status.operationState.phase in ['Error', 'Failed']
      send: [app-common]
  trigger.on-sync-running: |
    - when: app.status.operationState.phase in ['Running']
      send: [app-common]
  trigger.on-sync-status-unknown: |
    - when: app.status.sync.status == 'Unknown'
      send: [app-common]
  trigger.on-sync-succeeded: |
    - when: app.status.operationState.phase in ['Succeeded']
      send: [app-common]

but, in template cannot figure out that what trigger is triggering the webhook.

I want to get trigger name in template something like this..

  template.app-common: |
    webhook:
      forwarder:
        method: POST
        body: |-
          {
            "app": {
              "metadata": {
                "name": "{{.app.metadata.name}}",
                "trigger": "{{.triggerName}}" // on-sync-failed, on-sync-succeeded ....
              },

Use Cases

this feature will be useful when managing a custom webhook template.
