Delete a Cluster

When you no longer need a cluster, you can delete it. All the associated resources for the cluster are deleted, but data in the data store (i.e., s3 bucket) is not be deleted.

You can not delete the main cluster.

Prerequisites

The database access node must be up and running.

Procedure

This procedure can be carried out using the Administration API.

The examples in this procedure are written using Bash on a Linux terminal. You can also use other interfaces and languages to execute the curl commands.

Placeholder values are styled as Bash variables, starting with the dollar sign ($) and using UPPERCASE characters. Replace the placeholders with your own values before executing the curl command.

  1. Get information about the database by sending a GET request to the /api/v1/databases endpoint. For example:

    curl -k -X "GET" \
    "https://$EXASOL_IP/api/v1/databases" \
    -H "accept: application/json" \
    -H "Authorization: Basic $AUTH_TOKEN"

    The response will include the following:

    • Database ID
    • Database name
    • Database version
    • Provider type
    • Number of clusters in the database
    • Number of clusters running
    • Volumes

    Additional database parameters and hardware details may be included in the response depending on the configuration and platform.

  2. To find cluster information, send a GET request to the /api/v1/databases/DATABASE_ID/clusters endpoint. For example:

    curl -k -X "GET" \
    "https://$EXASOL_IP/api/v1/databases/$DATABASE_ID/clusters" \
    -H "accept: application/json" \
    -H "Authorization: Basic $AUTH_TOKEN"

  3. To delete a cluster, send a DELETE request to the /api/v1/databases/DATABASE_ID/clusters/CLUSTER_ID endpoint. For example:

    curl -k -X "DELETE" \
    "https://$EXASOL_IP/api/v1/databases/$DATABASE_ID/clusters/$CLUSTER_ID" \
    -H "accept: application/json" \
    -H "Authorization: Basic $AUTH_TOKEN"

Verification

To verify, send a GET request to the /api/v1/databases/DATABASE_ID/clusters endpoint. For example:

curl -k -X "GET" \
"https://$EXASOL_IP/api/v1/databases/$DATABASE_ID/clusters" \
-H "accept: application/json" \
-H "Authorization: Basic $AUTH_TOKEN"

The cluster is no longer listed.
