Subscribe to events

Azure CLI

Create an event subscription for the above topic using the az eventgrid system-topic event-subscription create command.

The following sample command creates an event subscription for the FleetGateCreated event.


az eventgrid system-topic event-subscription create \
  --name stes-fleet-gates-sales-before-dev \
  --resource-group $GROUP \
  --system-topic-name stpc-aks-resource-notifications \
  --included-event-types Microsoft.ResourceNotifications.AKSResources.FleetGateCreated \
  --advanced-filter data.resourceInfo.properties.target.id StringContains "fleets/flt-mgr-approvals-01" \
  --advanced-filter data.resourceInfo.properties.gateType StringIn Approval \
  --advanced-filter data.resourceInfo.properties.state StringIn Pending \
  --advanced-filter data.resourceInfo.properties.displayName StringContains "Check with sales teams" \
  --advanced-filter data.resourceInfo.properties.target.updateRunProperties.timing StringIn Before \
  --advanced-filter data.resourceInfo.properties.target.updateRunProperties.stage StringIn Dev \
  --endpoint-type azurefunction \
  --endpoint /subscriptions/$SUBSCRIPTION_ID/resourceGroups/$GROUP/providers/Microsoft.Web/sites/fap-process-fleet-events/functions/fa-handle-pre-dev-events \
  --max-delivery-attempts 10 \
  --event-ttl 120

If you don't specify included-event-types, all the event types are included by default.

To filter events from a specific resource, use the --subject-begins-with parameter. The example shows how to subscribe to FleetGateUpdated events for resources in a specified resource group.

az eventgrid system-topic event-subscription create \
  --name EVENTSUBSCRIPTIONNAME \
  --resource-group RESOURCEGROUPNAME \
  --system-topic-name SYSTEMTOPICNAME \
  --included-event-types Microsoft.ResourceNotifications.AKSResources.FleetGateUpdated \
  --advanced-filter data.resourceInfo.properties.target.id StringContains "fleets/flt-mgr-approvals-01" \
  --endpoint /subscriptions/$SUBSCRIPTION_ID/resourceGroups/$GROUP/providers/Microsoft.Web/sites/fap-process-fleet-events/functions/fa-handle-pre-dev-events \
  --endpoint-type azurefunction \
  --subject-begins-with /subscriptions/AZURESUBSCRIPTIONID/resourceGroups/RESOURCEGROUPNAME/

Azure PowerShell

Create an event subscription for the above topic using the New-AzEventGridSystemTopicEventSubscription command.

The following sample command creates an event subscription for the FleetGateCreated event.

New-AzEventGridSubscription `
  -EventSubscriptionName "stes-fleet-gates-sales-before-dev" `
  -Scope "/subscriptions/$SUBSCRIPTION_ID/resourceGroups/$GROUP/providers/Microsoft.EventGrid/systemTopics/stpc-aks-resource-notifications" `
  -IncludedEventType @("Microsoft.ResourceNotifications.AKSResources.FleetGateCreated") `
  -AdvancedFilter @(
    (New-AzEventGridAdvancedFilterObject -StringContainsAdvancedFilter -Key "data.resourceInfo.properties.target.id" -Value @("fleets/flt-mgr-approvals-01")),
    (New-AzEventGridAdvancedFilterObject -StringInAdvancedFilter -Key "data.resourceInfo.properties.gateType" -Value @("Approval")),
    (New-AzEventGridAdvancedFilterObject -StringInAdvancedFilter -Key "data.resourceInfo.properties.state" -Value @("Pending")),
    (New-AzEventGridAdvancedFilterObject -StringContainsAdvancedFilter -Key "data.resourceInfo.properties.displayName" -Value @("Check with sales teams")),
    (New-AzEventGridAdvancedFilterObject -StringInAdvancedFilter -Key "data.resourceInfo.properties.target.updateRunProperties.timing" -Value @("Before")),
    (New-AzEventGridAdvancedFilterObject -StringInAdvancedFilter -Key "data.resourceInfo.properties.target.updateRunProperties.stage" -Value @("Dev"))
  ) `
  -EndpointType AzureFunction `
  -Endpoint "/subscriptions/$SUBSCRIPTION_ID/resourceGroups/$GROUP/providers/Microsoft.Web/sites/fap-process-fleet-events/functions/fa-handle-pre-dev-events" `
  -MaxDeliveryAttempt 10

If you don’t specify -IncludedEventType, all event types are included by default

To filter events from a specific resource, use the -SubjectBeginsWith parameter. The example shows how to subscribe to FleetGateUpdated events for resources in a specified resource group.

New-AzEventGridSubscription `
  -EventSubscriptionName "EVENTSUBSCRIPTIONNAME" `
  -Scope "/subscriptions/AZURESUBSCRIPTIONID/resourceGroups/RESOURCEGROUPNAME/providers/Microsoft.EventGrid/systemTopics/SYSTEMTOPICNAME" `
  -IncludedEventType @("Microsoft.ResourceNotifications.AKSResources.FleetGateUpdated") `
  -AdvancedFilter @(
    (New-AzEventGridAdvancedFilterObject -StringContainsAdvancedFilter -Key "data.resourceInfo.properties.target.id" -Value @("fleets/flt-mgr-approvals-01"))
  ) `
  -EndpointType AzureFunction `
  -Endpoint "/subscriptions/$SUBSCRIPTION_ID/resourceGroups/$GROUP/providers/Microsoft.Web/sites/fap-process-fleet-events/functions/fa-handle-pre-dev-events" `
  -SubjectBeginsWith "/subscriptions/AZURESUBSCRIPTIONID/resourceGroups/RESOURCEGROUPNAME/"

Azure portal

    2. In the Subject Filters section, for Subject begins with, provide the value of the resource group in this format: /subscriptions/{subscription-id}/resourceGroups/{resourceGroup-id}.

      :::image type="content" source="./media/subscribe-to-resource-notifications-kubernetes-events/filter.png" alt-text="Screenshot that shows the Filters tab of the Create Event Subscription page." lightbox="./media/subscribe-to-resource-notifications-kubernetes-events/filter.png":::

  8. Then, select Create to create the event subscription.

Delete event subscription and system topic

Azure CLI

To delete the event subscription, use the az eventgrid system-topic event-subscription delete command. Here's an example:

az eventgrid system-topic event-subscription delete \
   --name EVENTSUBSCRIPTIONNAME \
   --resourcegroup RESOURCEGROUPNAME \
  --system-topic-name SYSTEMTOPICNAME

To delete the system topic, use the az eventgrid system-topic delete command. Here's an example:

az eventgrid system-topic delete \
  --name SYSTEMTOPICNAME \
  --resource-group RESOURCEGROUPNAME

Azure PowerShell

To delete an event subscription, use the Remove-AzEventGridSystemTopicEventSubscription command. Here's an example:

Remove-AzEventGridSystemTopicEventSubscription`
       -EventSubscriptionName EVENTSUBSCRIPTIONNAME`
       -ResourceGroupName RESOURCEGROUPNAME`
       -SystemTopicName SYSTEMTOPICNAME

To delete the system topic, use the Remove-AzEventGridSystemTopic command. Here's an example:

Remove-AzEventGridSystemTopic -ResourceGroupName RESOURCEGROUPNAME -Name SYSTEMTOPICNAME

Azure portal

  1. Sign in to the Azure portal.
  2. In the search bar, type Event Grid System Topics, and press ENTER.
  3. Select the system topic.
  4. On the Event Grid System Topic page, select Delete on the toolbar.

Filtering examples

Subscribe to Gate creation events to be notified of pending approvals.

You might want to route approvals to different people or teams. To achieve that, you can set up multiple subscriptions to the Event Grid System Topic, with different filters for each one. For example, if you have a team's clusters in a single update run group, you can filter on that group and set the endpoint to their Azure function which runs a post-update health check:

Azure CLI

az eventgrid system-topic event-subscription create \
  --name fleet-approvals-group-subscription \
  --resource-group <resource-group> \
  --system-topic-name system-topic-aksresources \
  --included-event-types Microsoft.ResourceNotifications.AKSResources.FleetGateCreated \
  --advanced-filter data.resourceInfo.properties.gateType StringIn Approval \
  --advanced-filter data.resourceInfo.properties.state StringIn Pending \
  --advanced-filter data.resourceInfo.properties.target.updateRunProperties.timing StringIn After \
  --advanced-filter data.resourceInfo.properties.target.updateRunProperties.group StringIn teamName-group \
  --endpoint-type azurefunction \
  --endpoint /subscriptions/$SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.Web/sites/teamname/functions/health-check

You can also use the gate displayName as a filter for events:

az eventgrid system-topic event-subscription create \
  --name fleet-approvals-group-subscription \
  --resource-group <resource-group> \
  --system-topic-name system-topic-aksresources \
  --included-event-types Microsoft.ResourceNotifications.AKSResources.FleetGateCreated \
  --advanced-filter data.resourceInfo.properties.gateType StringIn Approval \
  --advanced-filter data.resourceInfo.properties.state StringIn Pending \
  --advanced-filter data.resourceInfo.properties.displayName StringContains "Check with sales teams" \
  --endpoint-type eventhub \
  --endpoint /subscriptions/$SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.EventHub/namespaces/EVENTHUBNAMESPACE/eventhubs/EVENTHUBNAME

Azure PowerShell

    )
  ) `
  -EndpointType AzureFunction `
  -Endpoint "/subscriptions/<subscription-id>/resourceGroups/<resource-group>/providers/Microsoft.Web/sites/teamname/functions/health-check"

You can also use the gate displayName as a filter for events:


New-AzEventGridSubscription `
  -EventSubscriptionName "fleet-approvals-group-subscription" `
  -Scope "/subscriptions/<subscription-id>/resourceGroups/<resource-group>/providers/Microsoft.EventGrid/systemTopics/system-topic-aksresources" `

    (New-AzEventGridAdvancedFilterObject -StringInAdvancedFilter `
        -Key   "data.resourceInfo.properties.gateType" `
        -Value @("Approval")
    ),
    (New-AzEventGridAdvancedFilterObject -StringInAdvancedFilter `
        -Key   "data.resourceInfo.properties.state" `
        -Value @("Pending")
    ),
    (New-AzEventGridAdvancedFilterObject -StringContainsAdvancedFilter `
        -Key   "data.resourceInfo.properties.displayName" `
        -Value @("Check with sales teams")
    )
  ) `
  -EndpointType EventHub `

Azure portal

  1. Choose FleetGateCreated as the event type.

  2. In the Filters tab of the event subscription, choose the following advanced filters.

    Key = data.resourceInfo.properties.gateType
Operator = String contains 
Value = Approval

        AND

Key = data.resourceInfo.properties.state
Operator = String contains 
Value = Pending

        AND

Key = data.resourceInfo.properties.displayName
Operator = String contains 
Value = Check with sales teams
