Managing and deleting resources

---

Learn how Config Connector manages an existing resource and handles deleting resources.

Creating a resource

When you create a resource, Config Connector creates the resource if it doesn't exist. If a Google Cloud resource already exists with the same name, then Config Connector acquires the resource and manages it.

To learn more about creating resources, see Getting started.

You can also manage the resources using the resourceID field. To learn more, see Managing resources with the resourceID field.

Acquiring an existing resource

This section describes how you acquire an existing BigQuery resource with Config Connector.

Note: Some resources can only be acquired by using the resourceID field, and some cannot be acquired at all. To learn more, see Resources with restrictions around acquisition.

Before you begin

1. Enable the BigQuery API.
2. Confirm you have access to the bq command line tool. If you do not have bq, use Cloud Shell or install it with the gcloud CLI.

Acquiring a BigQuery dataset

Config Connector acquires, or takes control of, resources when the values in the manifest and the resource name match. If a resource does not have a name (for example, a Project ID), the ID of the resource is used.

By creating an empty BigQuery dataset and then acquiring the dataset with Config Connector, you learn how Config Connector handles existing resources.

1. Create a BigQuery dataset named bigquerydatasetsample with bq.

   bq --location=US mk \
   --dataset \
   --default_table_expiration 3600 \
   --description description \
   PROJECT_ID:bigquerydatasetsample

2. Copy the following contents into a file named bq-sample.yaml.

     apiVersion: bigquery.cnrm.cloud.google.com/v1beta1
     kind: BigQueryDataset
     metadata:
       name: bigquerydatasetsample
     spec:
       defaultTableExpirationMs: 3600000
       description: "BigQuery Dataset Sample"
       friendlyName: bigquerydataset-sample
       location: US
   

3. Apply the yaml to your cluster.

   kubectl apply --namespace CC_NAMESPACE -f bq-sample.yaml

   Replace CC_NAMESPACE with the namespace Config Connector manages resources from.

4. Use kubectl describe to see details on the dataset.

   kubectl describe --namespace CC_NAMESPACE bigquerydataset bigquerydatasetsample

   Replace CC_NAMESPACE with the namespace Config Connector manages resources from.

   The output from kubectl describe includes metadata on the resource's status and ownership.

Deleting the dataset

By default, after Config Connector acquires and manages a resource, deleting the object from your cluster will delete the resource. If you prefer to keep the dataset, set the resource's deletion-policy.

For example, deleting the manifest that acquired bigquerydataset-sample will delete the dataset from BigQuery.

1. You can delete the bigquerydataset-sample dataset with kubectl delete.

   kubectl delete --namespace CC_NAMESPACE -f bq-sample.yaml

   Replace CC_NAMESPACE with the namespace Config Connector manages resources from.

   The output of kubectl confirms the deletion. bigquerydataset.bigquery.cnrm.cloud.google.com "bigquerydatasetsample" deleted

2. Use bq to confirm the dataset no longer exists.

   bq show PROJECT_ID:bigquerydatasetsample

   The output of the command includes Not Found.

Resources with restrictions around acquisition

Resources with a service-generated resource ID

You can only acquire Google Cloud resources which have a service-generated resource ID by using the resourceID field.

The following Config Connector resources correspond to Google Cloud resources which have a service-generated resource ID:

• AccessContextManagerAccessPolicy
• ApigeeOrganization
• BillingBudgetsBudget
• CloudIdentityGroup
• CloudIdentityMembership
• ComputeFirewallPolicy
• DLPDeidentifyTemplate
• DLPInspectTemplate
• DLPJobTrigger
• DLPStoredInfoType
• Folder
• IAPBrand
• IAPIdentityAwareProxyClient
• IdentityPlatformTenant
• MonitoringAlertPolicy
• MonitoringGroup
• MonitoringNotificationChannel
• MonitoringUptimeCheckConfig
• RecaptchaEnterpriseKey
• ResourceManagerLien
• SQLSSLCert
• SecretManagerSecretVersion
• StorageNotification
• StorageTransferJob
• VertexAIDataset
• VertexAIIndex

Note: Folder is a special case. You can set its resourceID to the folder ID of an existing folder to acquire that folder. However, if you leave resourceID unspecified, Folder acquires the folder with the given displayName in the given parent folder/organization. If none can be found, then a new folder is created.

To learn about how to use the resourceID field, see Managing resources with the resourceID field.

Resources that cannot be acquired

The following Config Connector resources do not have support for acquiring existing Google Cloud resources:

• DataflowFlexTemplateJob
• FirestoreIndex
• IAMServiceAccountKey

Keeping resources after deletion

Warning: When deleting a Config Connector resource the associated Google Cloud resource is deleted by default. To keep the Google Cloud resource, add the following to the Config Connector resource YAML before deleting:

...
metadata:
  annotations:
    cnrm.cloud.google.com/deletion-policy: abandon
...

For example, the YAML for the BigQuery dataset described earlier including the abandon deletion policy is below:

apiVersion: bigquery.cnrm.cloud.google.com/v1beta1
kind: BigQueryDataset
metadata:
  name: bigquerydatasetsample
  annotations:
    cnrm.cloud.google.com/deletion-policy: abandon
spec:
  defaultTableExpirationMs: 3600000
  description: "BigQuery Dataset Sample"
  friendlyName: bigquerydataset-sample
  location: US
