Requirements ¶

The below requirements are needed on the host that executes this module.

boto
boto3
botocore
json
python >= 2.6

Parameters ¶

Parameter		Choices/Defaults	Comments
aws_access_key string			AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string			AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key
client_token -			Unique, case-sensitive identifier you provide to ensure the idempotency of the request. Up to 32 ASCII characters are allowed.
cluster -			The name of the cluster in which the service exists
debug_botocore_endpoint_logs boolean added in 2.8		Choices: no ← yes	Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
delay -		Default: 10	The time to wait before checking that the service is available
deployment_configuration -			Optional parameters that control the deployment_configuration; format is '{"maximum_percent":<integer>, "minimum_healthy_percent":<integer>}
desired_count -			The count of how many instances of the service. This parameter is required when state=present
ec2_url string			Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
force_new_deployment boolean added in 2.8		Choices: no yes	Force deployment of service even if there are no changes
health_check_grace_period_seconds - added in 2.8			Seconds to wait before health checking the freshly added/updated services. This option requires botocore >= 1.8.20.
launch_type - added in 2.7		Choices: EC2 FARGATE	The launch type on which to run your service
load_balancers -			The list of ELBs defined for this service
name - / required			The name of the service
network_configuration -			network configuration of the service. Only applicable for task definitions created with `awsvpc` network_mode. assign_public_ip requires botocore >= 1.8.4
	assign_public_ip boolean added in 2.7	Choices: no yes	Whether the task's elastic network interface receives a public IP address. This option requires botocore >= 1.8.4.
	security_groups - added in 2.6		A list of security group names or group IDs to associate with the task
	subnets - added in 2.6		A list of subnet IDs to associate with the task
placement_constraints - added in 2.4			The placement constraints for the tasks in the service
placement_strategy - added in 2.4			The placement strategy objects to use for tasks in your service. You can specify a maximum of 5 strategy rules per service
profile string			Uses a boto profile. Only works with boto >= 2.24.0.
region string			The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See aliases: aws_region, ec2_region
repeat -		Default: 10	The number of times to check that the service is available
role -			The name or full Amazon Resource Name (ARN) of the IAM role that allows your Amazon ECS container agent to make calls to your load balancer on your behalf. This parameter is only required if you are using a load balancer with your service, in a network mode other than `awsvpc`.
scheduling_strategy - added in 2.8		Choices: DAEMON REPLICA	The scheduling strategy, defaults to "REPLICA" if not given to preserve previous behavior
security_token string			AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token
service_registries - added in 2.8			describes service discovery registries this service will register with.
	arn -		Service discovery registry ARN
	container_name -		container name for service discovery registration
	container_port -		container port for service discovery registration
state - / required		Choices: present absent deleting	The desired state of the service
task_definition -			The task definition the service will run. This parameter is required when state=present
validate_certs boolean		Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

Notes ¶

Note

the service role specified must be assumable (i.e. have a trust relationship for the ecs service, ecs.amazonaws.com)
for details of the parameters and returns see https://boto3.readthedocs.io/en/latest/reference/services/ecs.html
An IAM role must have been previously created
If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN, AWS_REGION or EC2_REGION
Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file

Returned Facts ¶

Facts returned by this module are added/updated in the hostvars host facts and can be referenced by name just like any other host fact. They do not need to be registered in order to use them.

Fact	Returned	Description
service complex	when service existed and was deleted	Details of deleted service in the same structure described above for service creation.

Return Values ¶

Common return values are documented here, the following are the fields unique to this module:

Key			Returned	Description

	clusterArn string		always	The Amazon Resource Name (ARN) of the of the cluster that hosts the service.
	deploymentConfiguration complex		always	dictionary of deploymentConfiguration
		maximumPercent integer	always	maximumPercent param
		minimumHealthyPercent integer	always	minimumHealthyPercent param
	deployments list of complex		always	list of service deployments
	desiredCount integer		always	The desired number of instantiations of the task definition to keep running on the service.
	events list of complex		always	list of service events
	loadBalancers complex		always	A list of load balancer objects
		containerName string	always	The name of the container to associate with the load balancer.
		containerPort integer	always	The port on the container to associate with the load balancer.
		loadBalancerName string	always	the name
	pendingCount integer		always	The number of tasks in the cluster that are in the PENDING state.
	placementConstraints list of complex		always	List of placement constraints objects
		expression string	always	A cluster query language expression to apply to the constraint. Note you cannot specify an expression if the constraint type is distinctInstance.
		type string	always	The type of constraint. Valid values are distinctInstance and memberOf.
	placementStrategy list of complex		always	List of placement strategy objects
		field string	always	The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host, which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are CPU and MEMORY.
		type string	always	The type of placement strategy. Valid values are random, spread and binpack.
	runningCount integer		always	The number of tasks in the cluster that are in the RUNNING state.
	serviceArn string		always	The Amazon Resource Name (ARN) that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the region of the service, the AWS account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region :012345678910 :service/my-service .
