Quickly create a service Create a service using defined parameters

Creating a service using the console

You can create a service using the console.

Consider the following when you use the console:

There are two compute options that distribute your tasks.
- A capacity provider strategy causes Amazon ECS to distribute your tasks in one or across multiple capacity providers.
- A launch type causes Amazon ECS to launch our tasks directly on either Fargate or on the Amazon EC2 instances registered to your clusters.
Task definitions that use the awsvpc network mode or services configured to use a load balancer must have a networking configuration. By default, the console selects the default Amazon VPC along with all subnets and the default security group within the default Amazon VPC.
The default task placement strategy distributes tasks evenly across Availability Zones.
When you use the Launch Type for your service deployment, by default the service starts in the subnets in your cluster VPC.
For the capacity provider strategy, the console selects a compute option by default. The following describes the order that the console uses to select a default:
- If your cluster has a default capacity provider strategy defined, it is selected.
- If your cluster doesn't have a default capacity provider strategy defined but you have the Fargate capacity providers added to the cluster, a custom capacity provider strategy that uses the FARGATE capacity provider is selected.
- If your cluster doesn't have a default capacity provider strategy defined but you have one or more Auto Scaling group capacity providers added to the cluster, the Use custom (Advanced) option is selected and you need to manually define the strategy.
- If your cluster doesn't have a default capacity provider strategy defined and no capacity providers added to the cluster, the Fargate launch type is selected.
The default deployment failure detection default options are to use the Amazon ECS deployment circuit breaker option with the Rollback on failures option.

For more information, see Deployment circuit breaker.
If you want to use the blue/green deployment option, determine how CodeDeploy moves the applications. The following options are available:
- CodeDeployDefault.ECSAllAtOnce: Shifts all traffic to the updated Amazon ECS container at once
- CodeDeployDefault.ECSLinear10PercentEvery1Minutes: Shifts 10 percent of traffic every minute until all traffic is shifted.
- CodeDeployDefault.ECSLinear10PercentEvery3Minutes: Shifts 10 percent of traffic every 3 minutes until all traffic is shifted.
- CodeDeployDefault.ECSCanary10Percent5Minutes: Shifts 10 percent of traffic in the first increment. The remaining 90 percent is deployed five minutes later.
- CodeDeployDefault.ECSCanary10Percent15Minutes: Shifts 10 percent of traffic in the first increment. The remaining 90 percent is deployed 15 minutes later.
If you need an application to connect to other applications that run in Amazon ECS, determine the option that fits your architecture. For more information, see Interconnecting services.
You must use AWS CloudFormation or the AWS Command Line Interface to deploy a service that uses any of the following parameters:
- Tracking policy with a custom metric
- Update Service – You cannot update the awsvpc network configuration and the health check grace period.
For information about how to create a service using the AWS CLI, see create-service in the AWS Command Line Interface Reference.

For information about how to create a service using AWS CloudFormation, see AWS::ECS::Service in the AWS CloudFormation User Guide.

Quickly create a service

You can use the console to quickly create and deploy a service. The service has the following configuration:

Deploys in the VPC and subnets associated with your cluster
Deploys one task
Uses the rolling deployment
Uses the capacity provider strategy with your default capacity provider
Uses the deployment circuit breaker to detect failures and sets the option to automatically roll back the deployment on failure

To deploy a service using the default parameters follow these steps.

If you chose Custom, define the algorithm for placing tasks and the rules that are considered during task placement.
- Under Strategy, for Type and Field, choose the algorithm and the entity to use for the algorithm.
  
  You can enter a maximum of 5 strategies.
- Under Constraint, for Type and Expression, choose the rule and attribute for the constraint.
  
  For example, to set the constraint to place tasks on T2 instances, for the Expression, enter attribute:ecs.instance-type =~ t2.*.
  
  You can enter a maximum of 10 constraints.
If your task definition uses the awsvpc network mode, expand Networking. Use the following steps to specify a custom configuration.
1. For VPC, select the VPC to use.
2. For Subnets, select one or more subnets in the VPC that the task scheduler considers when placing your tasks.
  
  Important
  Only private subnets are supported for the awsvpc network mode. Tasks don't receive public IP addresses. Therefore, a NAT gateway is required for outbound internet access, and inbound internet traffic is routed through a load balancer.
3. For Security group, you can either select an existing security group or create a new one. To use an existing security group, select the security group and move to the next step. To create a new security group, choose Create a new security group. You must specify a security group name, description, and then add one or more inbound rules for the security group.

If your task uses a data volume that's compatible with configuration at deployment, you can configure the volume by expanding Volume.

The volume name and volume type are configured when you create a task definition revision and can't be changed when creating a service. To update the volume name and type, you must create a new task definition revision and create a service by using the new revision.

To configure this volume type Do this

You can choose either the operating system default or a specific file system type. The default for Linux is `XFS`. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start. For Infrastructure role, choose an IAM role with the necessary permissions that allow Amazon ECS to manage Amazon EBS volumes for tasks. You can attach the `AmazonECSInfrastructureRolePolicyForVolumes` managed policy to the role, or you can use the policy as a guide to create and attach an your own policy with permissions that meet your specific needs. For more information about the necessary permissions, see Amazon ECS infrastructure IAM role. For Encryption, choose Default if you want to use the Amazon EBS encryption by default settings. If your account has Encryption by default configured, the volume will be encrypted with the AWS Key Management Service (AWS KMS) key that's specified in the setting. If you choose Default and Amazon EBS default encryption isn't turned on, the volume will be unencrypted. If you choose Custom, you can specify an AWS KMS key of your choice for volume encryption. If you choose None, the volume will be unencrypted unless you have encryption by default configured, or if you create a volume from an encrypted snapshot. If you've chosen Custom for Encryption, you must specify the AWS KMS key that you want to use. For KMS key, choose an AWS KMS key or enter a key ARN. If you choose to encrypt your volume by using a symmetric customer managed key, make sure that you have the right permissions defined in your AWS KMS key policy. For more information, see Data encryption for Amazon EBS volumes.
