Gets or sets the minimum instance count. 

public int MinInstanceCount { get; set; }
member this.MinInstanceCount : int with get, set
Public Property MinInstanceCount As Integer

Property Value

Int32

The minimum instance count. Defaults to 1 if not provided.

Remarks

The MinInstanceCount property indicates the minimum number of instances that must be up to meet the EnsureAvailability safety check during operations like upgrade or deactivate node. The actual number that is used is max( MinInstanceCount, ceil( MinInstancePercentage/100.0 * InstanceCount) ).

Note, if InstanceCount is set to -1, during MinInstanceCount computation -1 is first converted into the number of nodes on which the instances are allowed to be placed according to the placement constraints on the service.
