**Example 1: To create a service with a Fargate task** The following ``create-service`` example shows how to create a service using a Fargate task. :: aws ecs create-service \ --cluster MyCluster \ --service-name MyService \ --task-definition sample-fargate:1 \ --desired-count 2 \ --launch-type FARGATE \ --platform-version LATEST \ --network-configuration "awsvpcConfiguration={subnets=[subnet-12344321],securityGroups=[sg-12344321],assignPublicIp=ENABLED}" \ --tags key=key1,value=value1 key=key2,value=value2 key=key3,value=value3 Output:: { "service": { "serviceArn": "arn:aws:ecs:us-west-2:123456789012:service/MyCluster/MyService", "serviceName": "MyService", "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster", "loadBalancers": [], "serviceRegistries": [], "status": "ACTIVE", "desiredCount": 2, "runningCount": 0, "pendingCount": 0, "launchType": "FARGATE", "platformVersion": "LATEST", "taskDefinition": "arn:aws:ecs:us-west-2:123456789012:task-definition/sample-fargate:1", "deploymentConfiguration": { "maximumPercent": 200, "minimumHealthyPercent": 100 }, "deployments": [ { "id": "ecs-svc/1234567890123456789", "status": "PRIMARY", "taskDefinition": "arn:aws:ecs:us-west-2:123456789012:task-definition/sample-fargate:1", "desiredCount": 2, "pendingCount": 0, "runningCount": 0, "createdAt": 1557119253.821, "updatedAt": 1557119253.821, "launchType": "FARGATE", "platformVersion": "1.3.0", "networkConfiguration": { "awsvpcConfiguration": { "subnets": [ "subnet-12344321" ], "securityGroups": [ "sg-12344321" ], "assignPublicIp": "ENABLED" } } } ], "roleArn": "arn:aws:iam::123456789012:role/aws-service-role/ecs.amazonaws.com/AWSServiceRoleForECS", "events": [], "createdAt": 1557119253.821, "placementConstraints": [], "placementStrategy": [], "networkConfiguration": { "awsvpcConfiguration": { "subnets": [ "subnet-12344321" ], "securityGroups": [ "sg-12344321" ], "assignPublicIp": "ENABLED" } }, "schedulingStrategy": "REPLICA", "tags": [ { "key": "key1", "value": "value1" }, { "key": "key2", "value": "value2" }, { "key": "key3", "value": "value3" } ], "enableECSManagedTags": false, "propagateTags": "NONE" } } **Example 2: To create a service using the EC2 launch type** The following ``create-service`` example shows how to create a service called ``ecs-simple-service`` with a task that uses the EC2 launch type. The service uses the ``sleep360`` task definition and it maintains 1 instantiation of the task. :: aws ecs create-service \ --cluster MyCluster \ --service-name ecs-simple-service \ --task-definition sleep360:2 \ --desired-count 1 Output:: { "service": { "serviceArn": "arn:aws:ecs:us-west-2:123456789012:service/MyCluster/ecs-simple-service", "serviceName": "ecs-simple-service", "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster", "loadBalancers": [], "serviceRegistries": [], "status": "ACTIVE", "desiredCount": 1, "runningCount": 0, "pendingCount": 0, "launchType": "EC2", "taskDefinition": "arn:aws:ecs:us-west-2:123456789012:task-definition/sleep360:2", "deploymentConfiguration": { "maximumPercent": 200, "minimumHealthyPercent": 100 }, "deployments": [ { "id": "ecs-svc/1234567890123456789", "status": "PRIMARY", "taskDefinition": "arn:aws:ecs:us-west-2:123456789012:task-definition/sleep360:2", "desiredCount": 1, "pendingCount": 0, "runningCount": 0, "createdAt": 1557206498.798, "updatedAt": 1557206498.798, "launchType": "EC2" } ], "events": [], "createdAt": 1557206498.798, "placementConstraints": [], "placementStrategy": [], "schedulingStrategy": "REPLICA", "enableECSManagedTags": false, "propagateTags": "NONE" } } **Example 3: To create a service that uses an external deployment controller** The following ``create-service`` example creates a service that uses an external deployment controller. :: aws ecs create-service \ --cluster MyCluster \ --service-name MyService \ --deployment-controller type=EXTERNAL \ --desired-count 1 Output:: { "service": { "serviceArn": "arn:aws:ecs:us-west-2:123456789012:service/MyCluster/MyService", "serviceName": "MyService", "clusterArn": "arn:aws:ecs:us-west-2:123456789012:cluster/MyCluster", "loadBalancers": [], "serviceRegistries": [], "status": "ACTIVE", "desiredCount": 1, "runningCount": 0, "pendingCount": 0, "launchType": "EC2", "deploymentConfiguration": { "maximumPercent": 200, "minimumHealthyPercent": 100 }, "taskSets": [], "deployments": [], "roleArn": "arn:aws:iam::123456789012:role/aws-service-role/ecs.amazonaws.com/AWSServiceRoleForECS", "events": [], "createdAt": 1557128207.101, "placementConstraints": [], "placementStrategy": [], "schedulingStrategy": "REPLICA", "deploymentController": { "type": "EXTERNAL" }, "enableECSManagedTags": false, "propagateTags": "NONE" } } **Example 4: To create a new service behind a load balancer** The following ``create-service`` example shows how to create a service that is behind a load balancer. You must have a load balancer configured in the same Region as your container instance. This example uses the ``--cli-input-json`` option and a JSON input file called ``ecs-simple-service-elb.json`` with the following content:: { "serviceName": "ecs-simple-service-elb", "taskDefinition": "ecs-demo", "loadBalancers": [ { "loadBalancerName": "EC2Contai-EcsElast-123456789012", "containerName": "simple-demo", "containerPort": 80 } ], "desiredCount": 10, "role": "ecsServiceRole" } Command:: aws ecs create-service \ --cluster MyCluster \ --service-name ecs-simple-service-elb \ --cli-input-json file://ecs-simple-service-elb.json Output:: { "service": { "status": "ACTIVE", "taskDefinition": "arn:aws:ecs:us-west-2:123456789012:task-definition/ecs-demo:1", "pendingCount": 0, "loadBalancers": [ { "containerName": "ecs-demo", "containerPort": 80, "loadBalancerName": "EC2Contai-EcsElast-123456789012" } ], "roleArn": "arn:aws:iam::123456789012:role/ecsServiceRole", "desiredCount": 10, "serviceName": "ecs-simple-service-elb", "clusterArn": "arn:aws:ecs:`_ in the *Amazon ECS Developer Guide*.
