Optimizing disruptive updates for single node deployments in an orchestration platform

A computer system comprising:

• a processor set;
• a set of one or more computer-readable storage media;
• and
• program instructions, collectively stored in the set of one or more storage media, for causing the processor set to perform the following computer operations:
• receive a patch of a disruptive update for a node in an orchestration platform, wherein the node is a control plane node that is configured to run workloads;
• generate a copy for the node in the orchestration platform;
• allocate the workloads for the node to the copy for the node;
• update the node using the patch of the disruptive update, wherein the workloads are running on the copy for the node when the node is updating;
• and
• allocate the workloads from the copy for the node back to the node upon finishing the disruptive update.

A computer program product for updating a node in an orchestration platform, the computer program product comprising:

• a set of one or more computer-readable storage media;
