SageMaker / Client / update_endpoint

update_endpoint#

SageMaker.Client.update_endpoint(**kwargs)#

Deploys the new EndpointConfig specified in the request, switches to using newly created endpoint, and then deletes resources provisioned for the endpoint using the previous EndpointConfig (there is no availability loss).

When SageMaker receives the request, it sets the endpoint status to Updating. After updating the endpoint, it sets the status to InService. To check the status of an endpoint, use the DescribeEndpoint API.

Note

You must not delete an EndpointConfig in use by an endpoint that is live or while the UpdateEndpoint or CreateEndpoint operations are being performed on the endpoint. To update an endpoint, you must create a new EndpointConfig.

If you delete the EndpointConfig of an endpoint that is active or being created or updated you may lose visibility into the instance type the endpoint is using. The endpoint must be deleted in order to stop incurring charges.

Parameters:

EndpointName (string) –
[REQUIRED]

The name of the endpoint whose configuration you want to update.
EndpointConfigName (string) –
[REQUIRED]

The name of the new endpoint configuration.
RetainAllVariantProperties (boolean) – When updating endpoint resources, enables or disables the retention of variant properties, such as the instance count or the variant weight. To retain the variant properties of an endpoint when updating it, set RetainAllVariantProperties to true. To use the variant properties specified in a new EndpointConfig call when updating an endpoint, set RetainAllVariantProperties to false. The default is false.
ExcludeRetainedVariantProperties (list) –
When you are updating endpoint resources with RetainAllVariantProperties, whose value is set to true, ExcludeRetainedVariantProperties specifies the list of type VariantProperty to override with the values provided by EndpointConfig. If you don’t specify a value for ExcludeRetainedVariantProperties, no variant properties are overridden.
- (dict) –
  
  Specifies a production variant property type for an Endpoint.
  
  If you are updating an endpoint with the RetainAllVariantProperties option of UpdateEndpointInput set to true, the VariantProperty objects listed in the ExcludeRetainedVariantProperties parameter of UpdateEndpointInput override the existing variant properties of the endpoint.
  - VariantPropertyType (string) – [REQUIRED]
    
    The type of variant property. The supported values are:
    - DesiredInstanceCount: Overrides the existing variant instance counts using the InitialInstanceCount values in the ProductionVariants of CreateEndpointConfig.
    - DesiredWeight: Overrides the existing variant weights using the InitialVariantWeight values in the ProductionVariants of CreateEndpointConfig.
    - DataCaptureConfig: (Not currently supported.)
DeploymentConfig (dict) –
The deployment configuration for an endpoint, which contains the desired deployment strategy and rollback configurations.
- BlueGreenUpdatePolicy (dict) – [REQUIRED]
  
  Update policy for a blue/green deployment. If this update policy is specified, SageMaker creates a new fleet during the deployment while maintaining the old fleet. SageMaker flips traffic to the new fleet according to the specified traffic routing configuration. Only one update policy should be used in the deployment configuration. If no update policy is specified, SageMaker uses a blue/green deployment strategy with all at once traffic shifting by default.
  - TrafficRoutingConfiguration (dict) – [REQUIRED]
    
    Defines the traffic routing strategy to shift traffic from the old fleet to the new fleet during an endpoint deployment.
    - Type (string) – [REQUIRED]
      
      Traffic routing strategy type.
      - ALL_AT_ONCE: Endpoint traffic shifts to the new fleet in a single step.
      - CANARY: Endpoint traffic shifts to the new fleet in two steps. The first step is the canary, which is a small portion of the traffic. The second step is the remainder of the traffic.
      - LINEAR: Endpoint traffic shifts to the new fleet in n steps of a configurable size.
    - WaitIntervalInSeconds (integer) – [REQUIRED]
      
      The waiting time (in seconds) between incremental steps to turn on traffic on the new endpoint fleet.
    - CanarySize (dict) –
      
      Batch size for the first step to turn on traffic on the new endpoint fleet. Value must be less than or equal to 50% of the variant’s total instance count.
      - Type (string) – [REQUIRED]
        
        Specifies the endpoint capacity type.
        
        INSTANCE_COUNT: The endpoint activates based on the number of instances.
        
        CAPACITY_PERCENT: The endpoint activates based on the specified percentage of capacity.
      - Value (integer) – [REQUIRED]
        
        Defines the capacity size, either as a number of instances or a capacity percentage.
    - LinearStepSize (dict) –
      
      Batch size for each step to turn on traffic on the new endpoint fleet. Value must be 10-50% of the variant’s total instance count.
      - Type (string) – [REQUIRED]
        
        Specifies the endpoint capacity type.
        
        INSTANCE_COUNT: The endpoint activates based on the number of instances.
        
        CAPACITY_PERCENT: The endpoint activates based on the specified percentage of capacity.
      - Value (integer) – [REQUIRED]
        
        Defines the capacity size, either as a number of instances or a capacity percentage.
  - TerminationWaitInSeconds (integer) –
    
    Additional waiting time in seconds after the completion of an endpoint deployment before terminating the old endpoint fleet. Default is 0.
  - MaximumExecutionTimeoutInSeconds (integer) –
    
    Maximum execution timeout for the deployment. Note that the timeout value should be larger than the total waiting time specified in TerminationWaitInSeconds and WaitIntervalInSeconds.
- AutoRollbackConfiguration (dict) –
  
  Automatic rollback configuration for handling endpoint deployment failures and recovery.
  - Alarms (list) –
    
    List of CloudWatch alarms in your account that are configured to monitor metrics on an endpoint. If any alarms are tripped during a deployment, SageMaker rolls back the deployment.
    - (dict) –
      
      An Amazon CloudWatch alarm configured to monitor metrics on an endpoint.
      - AlarmName (string) –
        
        The name of a CloudWatch alarm in your account.
RetainDeploymentConfig (boolean) – Specifies whether to reuse the last deployment configuration. The default value is false (the configuration is not reused).
