PatchRollout class
Patch rollout configuration specifications. Contains details on the concurrency control when applying patch(es) to all targeted VMs.

Properties
- disruptionBudget ↔ FixedOrPercent
-
The maximum number (or percentage) of VMs per zone to disrupt at any given
moment. The number of VMs calculated from multiplying the percentage by
the total number of VMs in a zone is rounded up. During patching, a VM is
considered disrupted from the time the agent is notified to begin until
patching has completed. This disruption time includes the time to complete
reboot and any post-patch steps. A VM contributes to the disruption budget
if its patching operation fails either when applying the patches, running
pre or post patch steps, or if it fails to respond with a success
notification before timing out. VMs that are not running or do not have an
active agent do not count toward this disruption budget. For zone-by-zone
rollouts, if the disruption budget in a zone is exceeded, the patch job
stops, because continuing to the next zone requires completion of the
patch process in the previous zone. For example, if the disruption budget
has a fixed value of
10
, and 8 VMs fail to patch in the current zone, the patch job continues to patch 2 VMs at a time until the zone is completed. When that zone is completed successfully, patching begins with 10 VMs at a time in the next zone. If 10 VMs in the next zone fail to patch, the patch job stops.read / write - hashCode → int
