Properties

AttrName

The name of the Amazon ECS service, such as sample-webapp .

public virtual string AttrName { get; }
Property Value

System.String

Remarks

CloudformationAttribute: Name

AttrServiceArn

Not currently supported in AWS CloudFormation .

public virtual string AttrServiceArn { get; }
Property Value

System.String

Remarks

CloudformationAttribute: ServiceArn

CapacityProviderStrategy

The capacity provider strategy to use for the service.

public virtual object CapacityProviderStrategy { get; set; }
Property Value

System.Object

Remarks

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.

Review the Capacity provider considerations in the Amazon Elastic Container Service Developer Guide.

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 an 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.

Property Value

System.Nullable<System.Double>

Remarks

For new services, if a desired count is not specified, a default value of 1 is used. When using the DAEMON scheduling strategy, the desired count is not required.

For existing services, if a desired count is not specified, it is omitted from the operation.

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ecs-service.html#cfn-ecs-service-desiredcount

EnableEcsManagedTags

Specifies whether to turn on Amazon ECS managed tags for the tasks within the service.

public virtual object EnableEcsManagedTags { get; set; }
Property Value

System.Object

Remarks

For more information, see Tagging your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide .

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ecs-service.html#cfn-ecs-service-enableecsmanagedtags

EnableExecuteCommand

Determines whether the execute command functionality is enabled for the service.

public virtual object EnableExecuteCommand { get; set; }
Property Value

System.Object

Remarks

If true , the execute command functionality is enabled for all containers in tasks as part of the service.

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ecs-service.html#cfn-ecs-service-enableexecutecommand

HealthCheckGracePeriodSeconds

The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.

public virtual Nullable<double> HealthCheckGracePeriodSeconds { get; set; }
Property Value

System.Nullable<System.Double>

Remarks

This is only used when your service is configured to use a load balancer. If your service has a load balancer defined and you don't specify a health check grace period value, the default value of 0 is used.

If you do not use an Elastic Load Balancing, we recomend that you use the startPeriod in the task definition healtch check parameters. For more information, see Health check .

If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds (about 69 years). During that time, the Amazon ECS service scheduler ignores health check status. This grace period can prevent the service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.

PropagateTags

Specifies whether to propagate the tags from the task definition or the service to the tasks in the service.

public virtual string PropagateTags { get; set; }
Property Value

System.String

Remarks

If no value is specified, the tags are not propagated. Tags can only be propagated to the tasks within the service during service creation. To add tags to a task after service creation, use the TagResource API action.

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ecs-service.html#cfn-ecs-service-propagatetags

Role

The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load balancer on your behalf.

Remarks

This parameter is only permitted if you are using a load balancer with your service and your task definition doesn't use the awsvpc network mode. If you specify the role parameter, you must also specify a load balancer object with the loadBalancers parameter.

If your account has already created the Amazon ECS service-linked role, that role is used for your service unless you specify a role here. The service-linked role is required if your task definition uses the awsvpc network mode or if the service is configured to use service discovery, an external deployment controller, multiple target groups, or Elastic Inference accelerators in which case you don't specify a role here. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide .

If your specified role has a path other than / , then you must either specify the full role ARN (this is recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ then you would specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide .
