  .. py:method:: can_paginate(operation_name)

        
    Check if an operation can be paginated.
    
    :type operation_name: string
    :param operation_name: The operation name.  This is the same name
        as the method name on the client.  For example, if the
        method name is ``create_foo``, and you'd normally invoke the
        operation as ``client.create_foo(**kwargs)``, if the
        ``create_foo`` operation can be paginated, you can use the
        call ``client.get_paginator("create_foo")``.
    
    :return: ``True`` if the operation can be paginated,
        ``False`` otherwise.


  .. py:method:: create_cluster(**kwargs)

    

    Creates a new Amazon ECS cluster. By default, your account will receive a ``default`` cluster when you launch your first container instance. However, you can create your own cluster with a unique name with the ``CreateCluster`` action.

    

    **Request Syntax**

  .. py:method:: deregister_container_instance(**kwargs)

    

    Deregisters an Amazon ECS container instance from the specified cluster. This instance will no longer be available to run tasks.

     

    If you intend to use the container instance for some other purpose after deregistration, you should stop all of the tasks running on the container instance before deregistration to avoid any orphaned tasks from consuming resources.

     

    Deregistering a container instance removes the instance from a cluster, but it does not terminate the EC2 instance; if you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.

     

    .. note::

      

      When you terminate a container instance, it is automatically deregistered from your cluster.

      

    

    **Request Syntax** 
    ::

      response = client.deregister_container_instance(
          cluster='string',
          containerInstance='string',
          force=True|False
      )
    :type cluster: string
    :param cluster: 

      The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance you want to deregister. If you do not specify a cluster, the default cluster is assumed.

      

    
    :type containerInstance: string
    :param containerInstance: **[REQUIRED]** 

      The container instance UUID or full Amazon Resource Name (ARN) of the container instance you want to deregister. The ARN contains the ``arn:aws:ecs`` namespace, followed by the region of the container instance, the AWS account ID of the container instance owner, the ``container-instance`` namespace, and then the container instance UUID. For example, arn:aws:ecs:*region* :*aws_account_id* :container-instance/*container_instance_UUID* .

      

    
    :type force: boolean
    :param force: 

      Force the deregistration of the container instance. If you have tasks running on the container instance when you deregister it with the ``force`` option, these tasks remain running and they will continue to pass Elastic Load Balancing load balancer health checks until you terminate the instance or the tasks stop through some other means, but they are orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler will start another copy of that task on a different container instance if possible.

          - **status** *(string) --* 

            The status of the container instance. The valid values are ``ACTIVE`` or ``INACTIVE`` . ``ACTIVE`` indicates that the container instance can accept tasks.

            
          

          - **agentConnected** *(boolean) --* 

            This parameter returns ``true`` if the agent is actually connected to Amazon ECS. Registered instances with an agent that may be unhealthy or stopped will return ``false`` , and instances without a connected agent cannot accept placement request.

            
          

          - **runningTasksCount** *(integer) --* 

            The number of tasks on the container instance that are in the ``RUNNING`` status.

            The number of tasks on the container instance that are in the ``PENDING`` status.

            
          

          - **agentUpdateStatus** *(string) --* 

            The status of the most recent agent update. If an update has never been requested, this value is ``NULL`` .

            
      
    

  .. py:method:: deregister_task_definition(**kwargs)

    

    Deregisters the specified task definition by family and revision. Upon deregistration, the task definition is marked as ``INACTIVE`` . Existing tasks and services that reference an ``INACTIVE`` task definition continue to run without disruption. Existing services that reference an ``INACTIVE`` task definition can still scale up or down by modifying the service's desired count.

     

    You cannot use an ``INACTIVE`` task definition to run new tasks or create new services, and you cannot update an existing service to reference an ``INACTIVE`` task definition (although there may be up to a 10 minute window following deregistration where these restrictions have not yet taken effect).

      **Response Structure** 

      

      - *(dict) --* 
        

        - **taskDefinition** *(dict) --* 

          The full description of the deregistered task.

          
          

          - **taskDefinitionArn** *(string) --* 

            The full Amazon Resource Name (ARN) of the of the task definition.

            
          

          - **containerDefinitions** *(list) --* 

            A list of container definitions in JSON format that describe the different containers that make up your task. For more information on container definition parameters and defaults, see `Amazon ECS Task Definitions`_ in the *Amazon EC2 Container Service Developer Guide* .

            
            

            - *(dict) --* 

              Container definitions are used in task definitions to describe the different containers that are launched as part of a task.

              
              

              - **name** *(string) --* 

                The name of a container. If you are linking multiple containers together in a task definition, the ``name`` of one container can be entered in the ``links`` of another container to connect the containers.

                
              

              - **image** *(string) --* 

                The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with ``*repository-url* /*image* :*tag*`` .

                
              

              - **cpu** *(integer) --* 

                The number of ``cpu`` units reserved for the container. A container instance has 1,024 ``cpu`` units for every CPU core. This parameter specifies the minimum amount of CPU to reserve for a container, and containers share unallocated CPU units with other containers on the instance with the same ratio as their allocated amount.

                 

                For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

                 

                The Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see `CPU share constraint`_ in the Docker documentation. The minimum valid CPU share value that the Linux kernel will allow is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:

                 

                 
                *  **Agent versions less than or equal to 1.1.0:** Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to 2 CPU shares.
                 
                *  **Agent versions greater than or equal to 1.2.0:** Null, zero, and CPU values of 1 are passed to Docker as 2.
                 

                
              

              - **memory** *(integer) --* 

                The number of MiB of memory reserved for the container. If your container attempts to exceed the memory allocated here, the container is killed.

                
              

              - **links** *(list) --* 

                The ``link`` parameter allows containers to communicate with each other without the need for port mappings, using the ``name`` parameter. The ``name:internalName`` construct is analogous to ``name:alias`` in Docker links. For more information on linking Docker containers, see `https\://docs.docker.com/userguide/dockerlinks/`_ .

                 

                .. warning::

                   

                  Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

                   

                
                

                - *(string) --* 
            
              

              - **portMappings** *(list) --* 

                The list of port mappings for the container.

                
                

                - *(dict) --* 

                  Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.

                  
                  

                  - **containerPort** *(integer) --* 

                    The port number on the container that is bound to the user-specified or automatically assigned host port. If you specify a container port and not a host port, your container will automatically receive a host port in the ephemeral port range (for more information, see ``hostPort`` ).

                    
                  

                  - **hostPort** *(integer) --* 

                    The port number on the container instance to reserve for your container. You can specify a non-reserved host port for your container port mapping, or you can omit the ``hostPort`` (or set it to ``0`` ) while specifying a ``containerPort`` and your container will automatically receive a port in the ephemeral port range for your container instance operating system and Docker version.

                     

                    The default ephemeral port range is 49153 to 65535, and this range is used for Docker versions prior to 1.6.0. For Docker version 1.6.0 and later, the Docker daemon tries to read the ephemeral port range from ``/proc/sys/net/ipv4/ip_local_port_range`` ; if this kernel parameter is unavailable, the default ephemeral port range is used. You should not attempt to specify a host port in the ephemeral port range, since these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

                     

                    The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS Container Agent port 51678. Any host port that was previously specified in a running task is also reserved while the task is running (once a task stops, the host port is released).The current reserved ports are displayed in the ``remainingResources`` of  DescribeContainerInstances output, and a container instance may have up to 50 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward this limit).

                    
                  

                  - **protocol** *(string) --* 

                    The protocol used for the port mapping. Valid values are ``tcp`` and ``udp`` . The default is ``tcp`` .

                    
              
            
              

              - **essential** *(boolean) --* 

                If the ``essential`` parameter of a container is marked as ``true`` , the failure of that container will stop the task. If the ``essential`` parameter of a container is marked as ``false`` , then its failure will not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

                 

                .. note::

                   

                  All tasks must have at least one essential container.

                   

                
              

              - **entryPoint** *(list) --* 

                .. warning::

                   

                  Early versions of the Amazon ECS container agent do not properly handle ``entryPoint`` parameters. If you have problems using ``entryPoint`` , update your container agent or enter your commands and arguments as ``command`` array items instead.

                   

                 

                The ``ENTRYPOINT`` that is passed to the container. For more information on the Docker ``ENTRYPOINT`` parameter, see `https\://docs.docker.com/reference/builder/#entrypoint`_ .

                
                

                - *(string) --* 
            
              

              - **command** *(list) --* 

                The ``CMD`` that is passed to the container. For more information on the Docker ``CMD`` parameter, see `https\://docs.docker.com/reference/builder/#cmd`_ .

      **Response Structure** 

      

      - *(dict) --* 
        

        - **taskDefinition** *(dict) --* 

          The full task definition description.

          
          

          - **taskDefinitionArn** *(string) --* 

            The full Amazon Resource Name (ARN) of the of the task definition.

            
          

          - **containerDefinitions** *(list) --* 

            A list of container definitions in JSON format that describe the different containers that make up your task. For more information on container definition parameters and defaults, see `Amazon ECS Task Definitions`_ in the *Amazon EC2 Container Service Developer Guide* .

            
            

            - *(dict) --* 

              Container definitions are used in task definitions to describe the different containers that are launched as part of a task.

              
              

              - **name** *(string) --* 

                The name of a container. If you are linking multiple containers together in a task definition, the ``name`` of one container can be entered in the ``links`` of another container to connect the containers.

                
              

              - **image** *(string) --* 

                The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with ``*repository-url* /*image* :*tag*`` .

                
              

              - **cpu** *(integer) --* 

                The number of ``cpu`` units reserved for the container. A container instance has 1,024 ``cpu`` units for every CPU core. This parameter specifies the minimum amount of CPU to reserve for a container, and containers share unallocated CPU units with other containers on the instance with the same ratio as their allocated amount.

                 

                For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

                 

                The Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see `CPU share constraint`_ in the Docker documentation. The minimum valid CPU share value that the Linux kernel will allow is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:

                 

                 
                *  **Agent versions less than or equal to 1.1.0:** Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to 2 CPU shares.
                 
                *  **Agent versions greater than or equal to 1.2.0:** Null, zero, and CPU values of 1 are passed to Docker as 2.
                 

                
              

              - **memory** *(integer) --* 

                The number of MiB of memory reserved for the container. If your container attempts to exceed the memory allocated here, the container is killed.

                
              

              - **links** *(list) --* 

                The ``link`` parameter allows containers to communicate with each other without the need for port mappings, using the ``name`` parameter. The ``name:internalName`` construct is analogous to ``name:alias`` in Docker links. For more information on linking Docker containers, see `https\://docs.docker.com/userguide/dockerlinks/`_ .

                 

                .. warning::

                   

                  Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

                   

                
                

                - *(string) --* 
            
              

              - **portMappings** *(list) --* 

                The list of port mappings for the container.

                
                

                - *(dict) --* 

                  Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.

                  
                  

                  - **containerPort** *(integer) --* 

                    The port number on the container that is bound to the user-specified or automatically assigned host port. If you specify a container port and not a host port, your container will automatically receive a host port in the ephemeral port range (for more information, see ``hostPort`` ).

                    
                  

                  - **hostPort** *(integer) --* 

                    The port number on the container instance to reserve for your container. You can specify a non-reserved host port for your container port mapping, or you can omit the ``hostPort`` (or set it to ``0`` ) while specifying a ``containerPort`` and your container will automatically receive a port in the ephemeral port range for your container instance operating system and Docker version.

                     

                    The default ephemeral port range is 49153 to 65535, and this range is used for Docker versions prior to 1.6.0. For Docker version 1.6.0 and later, the Docker daemon tries to read the ephemeral port range from ``/proc/sys/net/ipv4/ip_local_port_range`` ; if this kernel parameter is unavailable, the default ephemeral port range is used. You should not attempt to specify a host port in the ephemeral port range, since these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

                     

                    The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS Container Agent port 51678. Any host port that was previously specified in a running task is also reserved while the task is running (once a task stops, the host port is released).The current reserved ports are displayed in the ``remainingResources`` of  DescribeContainerInstances output, and a container instance may have up to 50 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward this limit).

                    
                  

                  - **protocol** *(string) --* 

                    The protocol used for the port mapping. Valid values are ``tcp`` and ``udp`` . The default is ``tcp`` .

                    
              
            
              

              - **essential** *(boolean) --* 

                If the ``essential`` parameter of a container is marked as ``true`` , the failure of that container will stop the task. If the ``essential`` parameter of a container is marked as ``false`` , then its failure will not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

                 

                .. note::

                   

                  All tasks must have at least one essential container.

                   

                
              

              - **entryPoint** *(list) --* 

                .. warning::

                   

                  Early versions of the Amazon ECS container agent do not properly handle ``entryPoint`` parameters. If you have problems using ``entryPoint`` , update your container agent or enter your commands and arguments as ``command`` array items instead.

The remaining results of the initial request can be seen by sending another ``ListTasks`` request with the returned ``nextToken`` value. This value can be between 1 and 100. If this parameter is not used, then ``ListTasks`` returns up to 100 results and a ``nextToken`` value if applicable.

      

    
    :type startedBy: string
    :param startedBy: 

      The ``startedBy`` value that you want to filter the task results with. Specifying a ``startedBy`` value will limit the results to tasks that were started with that value.

      

    
    :type serviceName: string
    :param serviceName: 

      The name of the service that you want to filter the ``ListTasks`` results with. Specifying a ``serviceName`` will limit the results to tasks that belong to that service.

      

    
    :type desiredStatus: string
    :param desiredStatus: 

      The task status that you want to filter the ``ListTasks`` results with. Specifying a ``desiredStatus`` of ``STOPPED`` will limit the results to tasks that are in the ``STOPPED`` status, which can be useful for debugging tasks that are not starting properly or have died or finished. The default status filter is ``RUNNING`` .

          The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with ``*repository-url* /*image* :*tag*`` .

          

        
        - **cpu** *(integer) --* 

          The number of ``cpu`` units reserved for the container. A container instance has 1,024 ``cpu`` units for every CPU core. This parameter specifies the minimum amount of CPU to reserve for a container, and containers share unallocated CPU units with other containers on the instance with the same ratio as their allocated amount.

           

          For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

           

          The Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see `CPU share constraint`_ in the Docker documentation. The minimum valid CPU share value that the Linux kernel will allow is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:

           

           
          *  **Agent versions less than or equal to 1.1.0:** Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to 2 CPU shares.
           
          *  **Agent versions greater than or equal to 1.2.0:** Null, zero, and CPU values of 1 are passed to Docker as 2.
           

          

        
        - **memory** *(integer) --* 

          The number of MiB of memory reserved for the container. If your container attempts to exceed the memory allocated here, the container is killed.

          

        
        - **links** *(list) --* 

          The ``link`` parameter allows containers to communicate with each other without the need for port mappings, using the ``name`` parameter. The ``name:internalName`` construct is analogous to ``name:alias`` in Docker links. For more information on linking Docker containers, see `https\://docs.docker.com/userguide/dockerlinks/`_ .

           

          .. warning::

             

            Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

             

          

        
          - *(string) --* 

          
      
        - **portMappings** *(list) --* 

          The list of port mappings for the container.

          

        
          - *(dict) --* 

            Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.

            

          
            - **containerPort** *(integer) --* 

              The port number on the container that is bound to the user-specified or automatically assigned host port. If you specify a container port and not a host port, your container will automatically receive a host port in the ephemeral port range (for more information, see ``hostPort`` ).

              

            
            - **hostPort** *(integer) --* 

              The port number on the container instance to reserve for your container. You can specify a non-reserved host port for your container port mapping, or you can omit the ``hostPort`` (or set it to ``0`` ) while specifying a ``containerPort`` and your container will automatically receive a port in the ephemeral port range for your container instance operating system and Docker version.

               

              The default ephemeral port range is 49153 to 65535, and this range is used for Docker versions prior to 1.6.0. For Docker version 1.6.0 and later, the Docker daemon tries to read the ephemeral port range from ``/proc/sys/net/ipv4/ip_local_port_range`` ; if this kernel parameter is unavailable, the default ephemeral port range is used. You should not attempt to specify a host port in the ephemeral port range, since these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

               

              The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS Container Agent port 51678. Any host port that was previously specified in a running task is also reserved while the task is running (once a task stops, the host port is released).The current reserved ports are displayed in the ``remainingResources`` of  DescribeContainerInstances output, and a container instance may have up to 50 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward this limit).

              

            
            - **protocol** *(string) --* 

              The protocol used for the port mapping. Valid values are ``tcp`` and ``udp`` . The default is ``tcp`` .

              

            
          
      
        - **essential** *(boolean) --* 

          If the ``essential`` parameter of a container is marked as ``true`` , the failure of that container will stop the task. If the ``essential`` parameter of a container is marked as ``false`` , then its failure will not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

           

          .. note::

             

            All tasks must have at least one essential container.

             

          

        
        - **entryPoint** *(list) --* 

          .. warning::

             

            Early versions of the Amazon ECS container agent do not properly handle ``entryPoint`` parameters. If you have problems using ``entryPoint`` , update your container agent or enter your commands and arguments as ``command`` array items instead.

             

           

          The ``ENTRYPOINT`` that is passed to the container. For more information on the Docker ``ENTRYPOINT`` parameter, see `https\://docs.docker.com/reference/builder/#entrypoint`_ .

          

        
          - *(string) --*

          - *(string) --* 

          
      
        - **environment** *(list) --*

          - *(dict) --* 

            A key and value pair object.

            

          
            - **name** *(string) --*

            - **value** *(string) --* 

              The value of the key value pair. For environment variables, this is the value of the environment variable.

              

            
          
      
        - **mountPoints** *(list) --*

            - **readOnly** *(boolean) --* 

              If this value is ``true`` , the container has read-only access to the volume. If this value is ``false`` , then the container can write to the volume. The default value is ``false`` .

              

            
          
      
        - **volumesFrom** *(list) --*

                    The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS Container Agent port 51678. Any host port that was previously specified in a running task is also reserved while the task is running (once a task stops, the host port is released).The current reserved ports are displayed in the ``remainingResources`` of  DescribeContainerInstances output, and a container instance may have up to 50 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward this limit).

                    
                  

                  - **protocol** *(string) --* 

                    The protocol used for the port mapping. Valid values are ``tcp`` and ``udp`` . The default is ``tcp`` .

                    
              
            
              

              - **essential** *(boolean) --* 

                If the ``essential`` parameter of a container is marked as ``true`` , the failure of that container will stop the task. If the ``essential`` parameter of a container is marked as ``false`` , then its failure will not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

                 

                .. note::

                   

                  All tasks must have at least one essential container.

                   

                
              

              - **entryPoint** *(list) --* 

                .. warning::

                   

                  Early versions of the Amazon ECS container agent do not properly handle ``entryPoint`` parameters. If you have problems using ``entryPoint`` , update your container agent or enter your commands and arguments as ``command`` array items instead.

    :type startedBy: string
    :param startedBy: 

      An optional tag specified when a task is started. For example if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the ``startedBy`` parameter. You can then identify which tasks belong to that job by filtering the results of a  ListTasks call with the ``startedBy`` value.

       

      If a task is started by an Amazon ECS service, then the ``startedBy`` parameter contains the deployment ID of the service that starts it.

  .. py:method:: update_container_agent(**kwargs)

    

    Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent does not interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.

     

    ``UpdateContainerAgent`` requires the Amazon ECS-optimized AMI or Amazon Linux with the ``ecs-init`` service installed and running. For help updating the Amazon ECS container agent on other operating systems, see `Manually Updating the Amazon ECS Container Agent`_ in the *Amazon EC2 Container Service Developer Guide* .

  .. py:method:: update_service(**kwargs)

    

    Modify the desired count or task definition used in a service.

     

    You can add to or subtract from the number of instantiations of a task definition in a service by specifying the cluster that the service is running in and a new ``desiredCount`` parameter.

     

    You can use ``UpdateService`` to modify your task definition and deploy a new version of your service, one task at a time. If you modify the task definition with ``UpdateService`` , Amazon ECS spawns a task with the new version of the task definition and then stops an old task after the new version is running. Because ``UpdateService`` starts a new version of the task before stopping an old version, your cluster must have capacity to support one more instantiation of the task when ``UpdateService`` is run. If your cluster cannot support another instantiation of the task used in your service, you can reduce the desired count of your service by one before modifying the task definition.
