Specifying a Disruption Budget for your Application — Rounding logic when specifying percentages
Values for minAvailable or maxUnavailable can be expressed as integers or as a percentage.

Values for minAvailable or maxUnavailable can be expressed as integers or as a percentage.
When you specify an integer, it represents a number of Pods. For instance, if you set minAvailable to 10, then 10 Pods must always be available, even during a disruption. When you specify a percentage by setting the value to a string representation of a percentage (eg. "50%"), it represents a percentage of total Pods. For instance, if you set minAvailable to "50%", then at least 50% of the Pods remain available during a disruption.
When you specify the value as a percentage, it may not map to an exact number of Pods. For example, if you have 7 Pods and you set minAvailable to "50%", it's not immediately obvious whether that means 3 Pods or 4 Pods must be available. Kubernetes rounds up to the nearest integer, so in this case, 4 Pods must be available. When you specify the value maxUnavailable as
