Create a new AWS::ECS::Service.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
capacity_provider_strategy (Union[IResolvable, Sequence[Union[IResolvable, CapacityProviderStrategyItemProperty, Dict[str, Any]]], None]) – The capacity provider strategy to use for the service. 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. A capacity provider strategy may contain a maximum of 6 capacity providers.
cluster (Optional[str]) – The short name or full Amazon Resource Name (ARN) of the cluster that you run your service on. If you do not specify a cluster, the default cluster is assumed.
deployment_configuration (Union[IResolvable, DeploymentConfigurationProperty, Dict[str, Any], None]) – Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deployment_controller (Union[IResolvable, DeploymentControllerProperty, Dict[str, Any], None]) – The deployment controller to use for the service. If no deployment controller is specified, the default value of ECS is used.
desired_count (Union[int, float, None]) – The number of instantiations of the specified task definition to place and keep running on your cluster. 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.
enable_ecs_managed_tags (Union[bool, IResolvable, None]) – Specifies whether to turn on Amazon ECS managed tags for the tasks within the service. For more information, see Tagging your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide .
enable_execute_command (Union[bool, IResolvable, None]) – Determines whether the execute command functionality is enabled for the service. If true , the execute command functionality is enabled for all containers in tasks as part of the service.
health_check_grace_period_seconds (Union[int, float, None]) – 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. 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 recommend that you use the startPeriod in the task definition health 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.
launch_type (Optional[str]) – The launch type on which to run your service. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
load_balancers (Union[IResolvable, Sequence[Union[LoadBalancerProperty, Dict[str, Any], IResolvable]], None]) – A list of load balancer objects to associate with the service. If you specify the Role property, LoadBalancers must be specified as well. For information about the number of load balancers that you can specify per service, see Service Load Balancing in the Amazon Elastic Container Service Developer Guide .
network_configuration (Union[NetworkConfigurationProperty, Dict[str, Any], IResolvable, None]) – The network configuration for the service. This parameter is required for task definitions that use the awsvpc network mode to receive their own elastic network interface, and it is not supported for other network modes. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
placement_constraints (Union[IResolvable, Sequence[Union[PlacementConstraintProperty, Dict[str, Any], IResolvable]], None]) – An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.
placement_strategies (Union[IResolvable, Sequence[Union[PlacementStrategyProperty, Dict[str, Any], IResolvable]], None]) – The placement strategy objects to use for tasks in your service. You can specify a maximum of 5 strategy rules for each service.
platform_version (Optional[str]) – The platform version that your tasks in the service are running on. A platform version is specified only for tasks using the Fargate launch type. If one isn’t specified, the LATEST platform version is used. For more information, see AWS Fargate platform versions in the Amazon Elastic Container Service Developer Guide .
propagate_tags (Optional[str]) – Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren’t propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.
role (Optional[str]) – 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. 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. .. epigraph:: 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 .
scheduling_strategy (Optional[str]) – The scheduling strategy to use for the service. For more information, see Services . There are two service scheduler strategies available: - REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. This scheduler strategy is required if the service uses the CODE_DEPLOY or EXTERNAL deployment controller types. - DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks and will stop tasks that don’t meet the placement constraints. When you’re using this strategy, you don’t need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies. .. epigraph:: Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don’t support the DAEMON scheduling strategy.
service_connect_configuration (Union[IResolvable, ServiceConnectConfigurationProperty, Dict[str, Any], None]) – The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace. Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
service_name (Optional[str]) – The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.
service_registries (Union[IResolvable, Sequence[Union[ServiceRegistryProperty, Dict[str, Any], IResolvable]], None]) – The details of the service discovery registry to associate with this service. For more information, see Service discovery . .. epigraph:: Each service may be associated with one service registry. Multiple service registries for each service isn’t supported.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well. The following basic restrictions apply to tags: - Maximum number of tags per resource - 50 - For each resource, each tag key must be unique, and each tag key can have only one value. - Maximum key length - 128 Unicode characters in UTF-8 - Maximum value length - 256 Unicode characters in UTF-8 - If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @. - Tag keys and values are case-sensitive. - Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
task_definition (Optional[str]) – The family and revision ( family:revision ) or full ARN of the task definition to run in your service. If a revision isn’t specified, the latest ACTIVE revision is used. A task definition must be specified if the service uses either the ECS or CODE_DEPLOY deployment controllers.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

scheduling_strategy

//docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs_services.html>`_ .

There are two service scheduler strategies available:

REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. This scheduler strategy is required if the service uses the CODE_DEPLOY or EXTERNAL deployment controller types.
DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks and will stop tasks that don’t meet the placement constraints. When you’re using this strategy, you don’t need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.

Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don’t support the DAEMON scheduling strategy.

Type:: The scheduling strategy to use for the service. For more information, see `Services <https

service_connect_configuration

The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .

stack

The stack in which this element is defined.

CfnElements must be defined within a stack scope (directly or indirectly).

tags

The metadata that you apply to the service to help you categorize and organize them.

Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.

The following basic restrictions apply to tags:

Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

CapacityProviderStrategyItemProperty

class CfnService.CapacityProviderStrategyItemProperty(*, base=None, capacity_provider=None, weight=None)

Bases: object

The details of a capacity provider strategy.

A capacity provider strategy can be set when using the RunTask or CreateService APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group 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 in a capacity provider strategy.

Parameters:

base (Union[int, float, None]) – The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
capacity_provider (Optional[str]) – The short name of the capacity provider.
weight (Union[int, float, None]) – The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied. If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can’t be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail. An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that’s run using capacityProviderA , four tasks would use capacityProviderB .

DeploymentAlarmsProperty

class CfnService.DeploymentAlarmsProperty(*, alarm_names, enable, rollback)

Bases: object

One of the methods which provide a way for you to quickly identify when a deployment has failed, and then to optionally roll back the failure to the last working deployment.

When the alarms are generated, Amazon ECS sets the service deployment to failed. Set the rollback parameter to have Amazon ECS to roll back your service to the last completed deployment after a failure.

You can only use the DeploymentAlarms method to detect failures when the DeploymentController is set to ECS (rolling update).

For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide .

Parameters:

alarm_names (Sequence[str]) – One or more CloudWatch alarm names. Use a “,” to separate the alarms.
enable (Union[bool, IResolvable]) – Determines whether to use the CloudWatch alarm option in the service deployment process.
rollback (Union[bool, IResolvable]) – Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

DeploymentCircuitBreakerProperty

class CfnService.DeploymentCircuitBreakerProperty(*, enable, rollback)

Bases: object

The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type.

The deployment circuit breaker determines whether a service deployment will fail if the service can’t reach a steady state. If enabled, a service deployment will transition to a failed state and stop launching new tasks. You can also configure Amazon ECS to roll back your service to the last completed deployment after a failure.

DeploymentConfigurationProperty

class CfnService.DeploymentConfigurationProperty(*, alarms=None, deployment_circuit_breaker=None, maximum_percent=None, minimum_healthy_percent=None)

Bases: object

The DeploymentConfiguration property specifies optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

Parameters:

alarms (Union[IResolvable, DeploymentAlarmsProperty, Dict[str, Any], None]) – Information about the CloudWatch alarms.
deployment_circuit_breaker (Union[IResolvable, DeploymentCircuitBreakerProperty, Dict[str, Any], None]) –

The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type. The deployment circuit breaker determines whether a service deployment will fail if the service can’t reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
maximum_percent (Union[int, float, None]) – If a service is using the rolling update ( ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service’s tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimum_healthy_percent (Union[int, float, None]) – If a service is using the rolling update ( ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service’s tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. For services that do not use a load balancer, the following should be noted: - A service is considered healthy if all essential containers within the tasks in the service pass their health checks. - If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total. - If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings. For services are that do use a load balancer, the following should be noted: - If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total. - If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

LoadBalancerProperty

class CfnService.LoadBalancerProperty(*, container_port, container_name=None, load_balancer_name=None, target_group_arn=None)

Bases: object

The LoadBalancer property specifies details on a load balancer that is used with a service.

If the service is using the CODE_DEPLOY deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When you are creating an AWS CodeDeploy deployment group, you specify two target groups (referred to as a targetGroupPair ). Each target group binds to a separate task set in the deployment. The load balancer can also have up to two listeners, a required listener for production traffic and an optional listener that allows you to test new revisions of the service before routing production traffic to it.

Services with tasks that use the awsvpc network mode (for example, those with the Fargate launch type) only support Application Load Balancers and Network Load Balancers. Classic Load Balancers are not supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance . Tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.

Parameters:

container_port (Union[int, float]) – The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they’re launched on must allow ingress traffic on the hostPort of the port mapping.
container_name (Optional[str]) – The name of the container (as it appears in a container definition) to associate with the load balancer.
load_balancer_name (Optional[str]) – The name of the load balancer to associate with the Amazon ECS service or task set. A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
target_group_arn (Optional[str]) – The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set. A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you’re using a Classic Load Balancer, omit the target group ARN. For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide . For services using the CODE_DEPLOY deployment controller, you’re required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide . .. epigraph:: If your service’s task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they’re launched on must allow ingress traffic on the hostPort of the port mapping.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-service-loadbalancer.html#cfn-ecs-service-loadbalancer-containerport

load_balancer_name

The name of the load balancer to associate with the Amazon ECS service or task set.

A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-service-loadbalancer.html#cfn-ecs-service-loadbalancer-loadbalancername

target_group_arn

The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you’re using a Classic Load Balancer, omit the target group ARN.

For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .

For services using the CODE_DEPLOY deployment controller, you’re required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide . .. epigraph:

If your service's task definition uses the ``awsvpc`` network mode, you must choose ``ip`` as the target type, not ``instance`` . Do this when creating your target groups because tasks that use the ``awsvpc`` network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

LogConfigurationProperty

class CfnService.LogConfigurationProperty(*, log_driver=None, options=None, secret_options=None)

Bases: object

The log configuration for the container.

This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to `docker run <https://docs.aws.amazon.com/https://docs.docker.com/engine/reference/commandline/run/>`_ .

By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

Understand the following when specifying a log configuration for your containers.

Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the valid values below). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .
For tasks that are on AWS Fargate , because you don’t have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

Parameters:

log_driver (Optional[str]) – The log driver to use for the container. For tasks on AWS Fargate , the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens . For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide . For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide . .. epigraph:: If you have a custom driver that isn’t listed, you can fork the Amazon ECS container agent project that’s available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don’t currently provide support for running modified copies of this software.
options (Union[IResolvable, Mapping[str, str], None]) – The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
secret_options (Union[IResolvable, Sequence[Union[IResolvable, SecretProperty, Dict[str, Any]]], None]) – The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .

ServiceRegistryProperty

class CfnService.ServiceRegistryProperty(*, container_name=None, container_port=None, port=None, registry_arn=None)

Bases: object

The ServiceRegistry property specifies details of the service registry.

For more information, see Service Discovery in the Amazon Elastic Container Service Developer Guide .

Parameters:

container_name (Optional[str]) – The container name value to be used for your service discovery service. It’s already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can’t specify both.
container_port (Union[int, float, None]) – The port value to be used for your service discovery service. It’s already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can’t specify both.
port (Union[int, float, None]) – The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
registry_arn (Optional[str]) – The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is AWS Cloud Map . For more information, see CreateService .
