For Bicep, set this value in the resource declaration.
'Microsoft.ServiceFabric/clusters/applications'
apiVersion The resource api version

For Bicep, set this value in the resource declaration.
'2019-03-01-preview'

See how to set names and types for child resources in Bicep or JSON ARM templates.
string (required)
location Azure resource location. string
tags Azure resource tags. Dictionary of tag names and values. See Tags in templates
properties The application resource properties. ApplicationResourceProperties

ApplicationResourceProperties

Name Description Value
maximumNodes The maximum number of nodes where Service Fabric will reserve capacity for this application. Note that this does not mean that the services of this application will be placed on all of those nodes. By default, the value of this property is zero and it means that the services can be placed on any node. int
metrics List of application capacity metric description. ApplicationMetricDescription[]
minimumNodes The minimum number of nodes where Service Fabric will reserve capacity for this application. Note that this does not mean that the services of this application will be placed on all of those nodes. If this property is set to zero, no capacity will be reserved. The value of this property cannot be more than the value of the MaximumNodes property. int
parameters List of application parameters with overridden values from their default values specified in the application manifest. object
removeApplicationCapacity Remove the current application capacity settings. bool
typeName The application type name as defined in the application manifest. string
typeVersion The version of the application type as defined in the application manifest. string
upgradePolicy Describes the policy for a monitored application upgrade. ApplicationUpgradePolicy

ApplicationMetricDescription

Name Description Value
maximumCapacity The maximum node capacity for Service Fabric application.
This is the maximum Load for an instance of this application on a single node. Even if the capacity of node is greater than this value, Service Fabric will limit the total load of services within the application on each node to this value.
If set to zero, capacity for this metric is unlimited on each node.
When creating a new application with application capacity defined, the product of MaximumNodes and this value must always be smaller than or equal to TotalApplicationCapacity.
When updating existing application with application capacity, the product of MaximumNodes and this value must always be smaller than or equal to TotalApplicationCapacity.
int
name The name of the metric. string
reservationCapacity The node reservation capacity for Service Fabric application.
This is the amount of load which is reserved on nodes which have instances of this application.
If MinimumNodes is specified, then the product of these values will be the capacity reserved in the cluster for the application.
If set to zero, no capacity is reserved for this metric.
When setting application capacity or when updating application capacity; this value must be smaller than or equal to MaximumCapacity for each metric.
int
totalApplicationCapacity The total metric capacity for Service Fabric application.
This is the total metric capacity for this application in the cluster. Service Fabric will try to limit the sum of loads of services within the application to this value.
When creating a new application with application capacity defined, the product of MaximumNodes and MaximumCapacity must always be smaller than or equal to this value.
int

ApplicationUpgradePolicy

Name Description Value
applicationHealthPolicy Defines a health policy used to evaluate the health of an application or one of its children entities. ArmApplicationHealthPolicy
forceRestart If true, then processes are forcefully restarted during upgrade even when the code version has not changed (the upgrade only changes configuration or data). bool
rollingUpgradeMonitoringPolicy The policy used for monitoring the application upgrade ArmRollingUpgradeMonitoringPolicy
upgradeReplicaSetCheckTimeout The maximum amount of time to block processing of an upgrade domain and prevent loss of availability when there are unexpected issues. When this timeout expires, processing of the upgrade domain will proceed regardless of availability loss issues. The timeout is reset at the start of each upgrade domain. Valid values are between 0 and 42949672925 inclusive. (unsigned 32-bit integer). string

ArmApplicationHealthPolicy

Name Description Value
considerWarningAsError Indicates whether warnings are treated with the same severity as errors. bool
defaultServiceTypeHealthPolicy Represents the health policy used to evaluate the health of services belonging to a service type. ArmServiceTypeHealthPolicy
maxPercentUnhealthyDeployedApplications The maximum allowed percentage of unhealthy deployed applications. Allowed values are Byte values from zero to 100.
The percentage represents the maximum tolerated percentage of deployed applications that can be unhealthy before the application is considered in error.
This is calculated by dividing the number of unhealthy deployed applications over the number of nodes where the application is currently deployed on in the cluster.
The computation rounds up to tolerate one failure on small numbers of nodes. Default percentage is zero.
int
serviceTypeHealthPolicyMap Defines a ServiceTypeHealthPolicy per service type name.

The entries in the map replace the default service type health policy for each specified service type.
For example, in an application that contains both a stateless gateway service type and a stateful engine service type, the health policies for the stateless and stateful services can be configured differently.
With policy per service type, there's more granular control of the health of the service.

If no policy is specified for a service type name, the DefaultServiceTypeHealthPolicy is used for evaluation.
object

ArmServiceTypeHealthPolicy

Name Description Value
maxPercentUnhealthyPartitionsPerService The maximum percentage of partitions per service allowed to be unhealthy before your application is considered in error. int
maxPercentUnhealthyReplicasPerPartition The maximum percentage of replicas per partition allowed to be unhealthy before your application is considered in error. int
maxPercentUnhealthyServices The maximum percentage of services allowed to be unhealthy before your application is considered in error. int

ArmRollingUpgradeMonitoringPolicy

Name Description Value
failureAction The activation Mode of the service package 'Manual'
'Rollback'
healthCheckRetryTimeout The amount of time to retry health evaluation when the application or cluster is unhealthy before FailureAction is executed. It is first interpreted as a string representing an ISO 8601 duration. If that fails, then it is interpreted as a number representing the total number of milliseconds. string
healthCheckStableDuration The amount of time that the application or cluster must remain healthy before the upgrade proceeds to the next upgrade domain. It is first interpreted as a string representing an ISO 8601 duration. If that fails, then it is interpreted as a number representing the total number of milliseconds. string
healthCheckWaitDuration The amount of time to wait after completing an upgrade domain before applying health policies. It is first interpreted as a string representing an ISO 8601 duration. If that fails, then it is interpreted as a number representing the total number of milliseconds. string
upgradeDomainTimeout The amount of time each upgrade domain has to complete before FailureAction is executed. It is first interpreted as a string representing an ISO 8601 duration. If that fails, then it is interpreted as a number representing the total number of milliseconds. string
upgradeTimeout The amount of time the overall upgrade has to complete before FailureAction is executed. It is first interpreted as a string representing an ISO 8601 duration. If that fails, then it is interpreted as a number representing the total number of milliseconds. string
