# -- Main application web-pod's
# @default -- *See single entries  below for details*
appServer:
  disruptionBudget:
    # -- (int) Number of pods allowed to be unavailable (exclusive, not allowed in combination with minAvailable)
    # @default -- `1`
    maxUnavailable: ~

and

# -- Main application web-pod's
# @default -- *See single entries  below for details*
appServer:
  disruptionBudget:
    # -- (int) Number of pods allowed to be unavailable (exclusive, not allowed in combination with minAvailable)
    # @default -- `1`
    maxUnavailable:
