Description

Starts a new task using the specified task definition. You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide. Alternatively, you can use StartTask to use your own scheduler or place tasks manually on specific container instances. The Amazon ECS API follows an eventual consistency model, due to the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command. To manage eventual consistency, you can do the following:
  • Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.
  • Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.

Parameters

-AwsvpcConfiguration_AssignPublicIp <AssignPublicIp>
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesNetworkConfiguration_AwsvpcConfiguration_AssignPublicIp
-AwsvpcConfiguration_SecurityGroup <String[]>
The security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration.All specified security groups must be from the same VPC.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesNetworkConfiguration_AwsvpcConfiguration_SecurityGroups
-AwsvpcConfiguration_Subnet <String[]>

-CapacityProviderStrategy <CapacityProviderStrategyItem[]>
The capacity provider strategy to use for the task.A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.To use a AWS Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The AWS Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.
