The notification template is used to generate the notification content and configured in argocd-notifications-cm ConfigMap. The template is leveraging html/template golang package and allow to customize notification message. Templates are meant to be reusable and can be referenced by multiple triggers.

The following template is used to notify the user about application sync status.

apiVersion: v1
kind: ConfigMap
  name: argocd-notifications-cm
data: |
    message: |
      Application {{}} sync is {{.app.status.sync.status}}.
      Application details: {{.context.argocdUrl}}/applications/{{}}.

Each template has access to the following fields:

  • app holds the application object.
  • context is user defined string map and might include any string keys and values.
  • serviceType holds the notification service type name. The field can be used to conditionally render service specific fields.
  • recipient holds the recipient name.

Defining user-defined context

It is possible to define some shared context between all notification templates by setting a top-level YAML document of key-value pairs, which can then be used within templates, like so:

apiVersion: v1
kind: ConfigMap
  name: argocd-notifications-cm
  context: |
    region: east
    environmentName: staging

  template.a-slack-template-with-context: |
    message: "Something happened in {{ .context.environmentName }} in the {{ .context.region }} data center!"

Notification Service Specific Fields

The message field of the template definition allows creating a basic notification for any notification service. You can leverage notification service-specific fields to create complex notifications. For example using service-specific you can add blocks and attachments for Slack, subject for Email or URL path, and body for Webhook. See corresponding service documentation for more information.

Change the timezone

You can change the timezone to show it as follows.

  1. Call time functions.
{{ (call .time.Parse .app.status.operationState.startedAt).Local.Format "2006-01-02T15:04:05Z07:00" }}
  1. Set environment to container.
apiVersion: apps/v1
kind: Deployment
  name: argocd-notifications-controller
      - name: argocd-notifications-controller
        - name: TZ
          value: Asia/Tokyo


Templates have access to the set of built-in functions:

apiVersion: v1
kind: ConfigMap
  name: argocd-notifications-cm
data: |
    message: "Author: {{(call .repo.GetCommitMetadata .app.status.sync.revision).Author}}"
