Cassandra Operations Task CassandraTask
The CassandraTask is a Custom Resource Definition (CRD) that enables you to perform operational tasks on your database clusters.
You create and manage these tasks using kubectl.
To create a task, you apply a YAML manifest file that specifies the operation you want to perform. For example, to restart a cluster:
kubectl apply -f restart-task.yamlThe manifest filename indicates the type of operation, such as restart-task.yaml, and the spec.jobs.command: field contains the specific task value, such as restart.
|
DataStax Mission Control provides several release-specific CRDs for use with the UI, While additional CRDs exist in a Mission Control installation, you should only interact with the documented CRDs unless directed by DataStax support. |
