Delete an instance

You can delete an instance programmatically when you use one of the Bigtable client libraries or manually using the Google Cloud console, the Google Cloud CLI, or the cbt CLI :

Console

  1. Open the list of Bigtable instances in the Google Cloud console.

    Open the instance list

  2. Click the instance you want to delete, then click Delete instance. A confirmation dialog appears.

  3. Follow the instructions in the confirmation dialog, then click Delete. The instance is permanently deleted.

gcloud

  1. Install the Google Cloud CLI if you haven't already.

  2. If you don't know the instance ID, use the bigtable instances list command to view a list of your project's instances: 

    gcloud bigtable instances list

  3. Use the bigtable instances delete command to delete an instance:

    gcloud bigtable instances delete INSTANCE_ID

    Replace INSTANCE_ID with the permanent identifier for your instance.

cbt

  1. Install the cbt CLI if you haven't already.

  2. If you don't know the instance ID, use the listinstances command to view a list of your project's instances: 

    cbt listinstances

  3. Use the deleteinstance command to delete an instance:

    cbt deleteinstance INSTANCE_ID

    Replace INSTANCE_ID with the permanent identifier for your instance.
