Shutdown of preemptible nodes on managed clusters

A cloud computing system, comprising:

• one or more processors;
• and
• one or more memories storing computer-executable instructions that, when executed by the one or more processors, cause the cloud computing system to:
• execute a cluster management service configured to manage a cluster comprising a plurality of nodes that are individually configured to execute one or more containerized applications;
• receive a request for a preemptible node;
• execute operations that cause the preemptible node to be generated and associated with a label that indicates a preemptible capacity type;
• and
• responsive to detecting that the preemptible node is associated with the label, deploy a containerized application to the preemptible node, the containerized application being configured to detect preemption of the preemptible node and trigger the cluster management service to execute a set of shutdown operations corresponding to the preemptible node.

A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by one or more processors of a cloud computing system, cause the one or more processors of the cloud computing system to:

• execute a cluster management service configured to manage a cluster comprising a plurality of nodes that are individually configured to execute one or more containerized applications;
• receive a request for a preemptible node;
• execute operations that cause the preemptible node to be generated and associated with a label that indicates a preemptible capacity type;
• and
• responsive to detecting that the preemptible node is associated with the label, deploy a containerized application to the preemptible node, the containerized application being configured to detect preemption of the preemptible node and trigger the cluster management service to execute a set of shutdown operations corresponding to the preemptible node.
