Delete Cloud Composer environments

Cloud Composer 3 | Cloud Composer 2 | Cloud Composer 1

This page explains how to delete your Cloud Composer environment.

Resources that are not deleted automatically

Deleting your environment does not delete the following data in your project:

• Your environment's Cloud Storage bucket.

• Cloud Logging logs.

• 2 GB persistent disk used by the Redis queue.

To avoid incurring charges to your Google Cloud account, export your data and delete the environment's bucket , Cloud Logging logs, and the Redis persistent disk, as needed.

Note: As an alternative, you can reuse your environment's bucket by specifying it as a custom bucket for a new environment. For example, you can do so to preserve existing policies or CI/CD integrations.

If you use alerting policies to monitor your environment's metrics, delete these policies before deleting your environment.

Your environment's cluster is deleted automatically

Warning: Do not delete the GKE cluster of your environment manually. This happens automatically during the environment deletion. If you delete the cluster before the environment, then attempting to delete your environment results in an error. To fix this problem, see Troubleshooting.

Delete a Cloud Composer environment

Console

1. Delete the Cloud Composer environment:

   1. In the Google Cloud console, go to the Environments page.

      Go to Environments

   2. Select your environment and click Delete.

   3. Wait until the environment is deleted.

2. Delete your environment's bucket. Cloud Composer does not delete the environment's bucket automatically.

   Warning: Deleting your environment's bucket deletes all objects stored within the bucket, such as DAGs and plugins. These objects cannot be recovered after you delete the bucket.

   1. In the Google Cloud console, go to the Storage > Browser page.

      Go to Storage > Browser

   2. Select the environment's bucket and click Delete. For example, this bucket can be named us-central1-example-environ-c1616fe8-bucket.

3. Delete the persistent disk of your environment's Redis queue. Deleting the Cloud Composer environment does not delete its persistent disk.

   1. In the Google Cloud console, go to the Compute Engine > Disks.

      Go to Disks

   2. Select the environment's Redis queue persistent disk and click Delete.

      For example, this disk can be named pvc-02bc4842-2312-4347-8519-d87bdcd31115. Disks for Cloud Composer 2 always have the Balanced persistent disk type and the size of 2 GB.

gcloud

1. Delete the Cloud Composer environment:

   gcloud composer environments delete ENVIRONMENT_NAME \
       --location LOCATION
   

   Replace:

   • ENVIRONMENT_NAME with the name of the environment.
   • LOCATION with the region where the environment is located.

2. Delete your environment's bucket. Cloud Composer does not delete the environment's bucket automatically.

   Warning: Deleting your environment's bucket deletes all objects stored within the bucket, such as DAGs and plugins. These objects cannot be recovered after you delete the bucket.

   gcloud storage rm gs://BUCKET_NAME --recursive
   

   Replace:

   • BUCKET_NAME with the name of your environment's bucket. For example, this bucket can be named us-central1-example-environ-c1616fe8-bucket.

3. Delete the persistent disk of your environment's Redis queue. Deleting the Cloud Composer environment does not delete its persistent disk.

   You can run gcloud compute disks list to list all disks in your project.

   To delete your environment's persistent disk:

   gcloud compute disks delete PD_NAME \
     --region=PD_LOCATION
   

   Replace:

   • PD_NAME with the name of the persistent disk for your environment

     For example, this disk can be named pvc-02bc4842-2312-4347-8519-d87bdcd31115. Disks for Cloud Composer 2 always have the pd-balanced type and the size of 2 GB.

   • PD_LOCATION with the location of the persistent disk. For example, the location can be us-central1-a.

API

To delete an environment, construct an environments.delete API request with the environment ID.

Caution: Cloud Composer does not automatically delete the environment's bucket and the persistent disk of the environment's Redis queue. If these components are no longer needed, delete them manually.

Terraform

To delete an environment using Terraform, remove the Cloud Composer configuration from your overall resource configuration and run terraform apply.

Caution: Cloud Composer does not automatically delete the environment's bucket and the persistent disk of the environment's Redis queue. If these components are no longer needed, delete them manually.
