autoscaling.maxReplicas	int	10
autoscaling.minReplicas	int	3
autoscaling.targetCPUUtilizationPercentage	int	75
configSecretName	string	nil	If provided, this secret will be used instead of the config created from the helm value scope
configSecretProperty	string	"wg0.conf"	The property/key on the secret holding the wireguard configuration file

deploymentStrategy.rollingUpdate.maxSurge	int	1
deploymentStrategy.rollingUpdate.maxUnavailable	int	0

disableConfigManagement	bool	false	Disable creation and any mount of the wireguard confifugration file, this assumes another mechanism is provided/used to manage a configuration file
