ecs-cli up

Creates the Amazon ECS cluster (if it does not already exist) and the AWS resources required to set up the cluster.

This command creates a new AWS CloudFormation stack called amazon-ecs-cli-setup-cluster_name. You can view the progress of the stack creation in the AWS Management Console.

Important

Some features described might only be available with the latest version of the Amazon ECS CLI. For more information about obtaining the latest version, see Installing the Amazon ECS CLI.

Options

Name	Description
`--capability-iam`	Acknowledges that this command may create IAM resources. Note This parameter is only supported with tasks that use the EC2 launch type. This parameter is required if you do not specify and instance profile name with `--instance-role`. You cannot specify both options. Required: No
`--keypair keypair_name`	Specifies the name of an existing Amazon EC2 key pair to enable SSH access to the EC2 instances in your cluster. Note This parameter is only supported with tasks that use the EC2 launch type. For more information about creating a key pair, see Setting Up with Amazon EC2 in the Amazon EC2 User Guide for Linux Instances. Type: String Required: No
`--size n`	Specifies the number of instances to launch and register to the cluster. Note This parameter is only supported with tasks that use the EC2 launch type. Type: Integer Default: 1 Required: No
`--azs availability_zone_1,availability_zone_2`	Specifies a comma-separated list of two VPC Availability Zones in which to create subnets (these zones must have the `available` status). We recommend this option if you do not specify a VPC ID with the `--vpc` option. Warning Leaving this option blank can result in a failure to launch container instances when the randomly chosen zone is unavailable. Type: String Required: No
`--security-group security_group_id[,security_group_id[,...]]`	Specifies a comma-separated list of existing security groups to associate with your container instances. If you do not specify a security group here, then a new one is created. For more information, see Security Groups in the Amazon EC2 User Guide for Linux Instances. Required: No
`--cidr ip_range`	Specifies a CIDR/IP range for the security group to use for container instances in your cluster. Note This parameter is ignored if an existing security group is specified with the `--security-group` option. Type: CIDR/IP range Default: `0.0.0.0/0` Required: No
`--port port_number`	Specifies a port to open on the security group to use for container instances in your cluster. Note This parameter is ignored if an existing security group is specified with the `--security-group` option. Type: Integer Default: `80` Required: No
`--subnets subnet_1,subnet_2`	Specifies a comma-separated list of existing VPC subnet IDs in which to launch your container instances. Type: String Required: This option is required if you specify a VPC with the `--vpc` option.
`--vpc vpc_id`	Specifies the ID of an existing VPC in which to launch your container instances. If you specify a VPC ID, you must specify a list of existing subnets in that VPC with the `--subnets` option. If you do not specify a VPC ID, a new VPC is created with two subnets. Type: String Required: No
`--extra-user-data string`	Specifies additional user data for your container instance. Files can be shell scripts or cloud-init directives. They are packaged into a MIME multipart archive along with user data provided by the Amazon ECS CLI that directs instances to join your cluster. For more information, see Specifying User Data. Type: String Required: No
`--instance-type instance_type`	Specifies the Amazon EC2 instance type for your container instances. If you specify an A1 instance type, for example `a1.medium`, and omit the `--image-id` parameter, the ECS CLI uses the the Amazon ECS-optimized Amazon Linux 2 (arm64) AMI AMI ID for the container instance. Note This parameter is supported only with tasks that use the EC2 launch type. For more information on EC2 instance types, see Amazon EC2 Instances. Type: String Default: `t2.micro` Required: No
`--image-id ami_id`	Specifies the Amazon EC2 AMI ID to use for your container instances. If you don't specify an AMI ID, the Amazon ECS CLI automatically retrieves the latest stable Amazon ECS-optimized Amazon Linux 2 AMI by querying the SSM Parameter Store API during the cluster resource creation process. This requires the user account that you're using to have the required SSM permissions. For more information, see Retrieving Amazon ECS-Optimized AMI Metadata. If you specify an A1 instance type for the `--instance-type` parameter and omit the `--image-id` parameter, the ECS CLI uses the the Amazon ECS-optimized Amazon Linux 2 (arm64) AMI AMI ID for the container instance. Note This parameter is supported only with tasks that use the EC2 launch type. Type: String Default: The latest stable Amazon ECS–optimized AMI for the specified Region. Required: No
`--no-associate-public-ip-address`	Do not assign public IP addresses to new instances in this VPC. Unless this option is specified, new instances in this VPC receive an automatically assigned public IP address. Note This parameter is only supported with tasks that use the EC2 launch type. Required: No
`--force, -f`	Forces the recreation of any existing resources that match your current configuration. This option is useful for cleaning up stale resources from previous failed attempts. Required: No
`--tags key1=value1,key2=value2`	Specifies the metadata to apply to your AWS resources. Each tag consists of a key and an optional value. Tags use the following format: `key1=value1,key2=value2,key3=value3`. For more information, see Tagging Resources. Type: Key value pairs Required: No
`--instance-role, -f instance-profile-name`	Specifies a custom IAM instance profile name for instances in your cluster. Note This parameter is only supported with tasks that use the EC2 launch type. This parameter is required if you do not specify the `--capability-iam` option. You cannot specify both options. Required: No
`--launch-type launch_type`	Specifies the launch type to use. Available options are `FARGATE` or `EC2`. For more information about launch types, see Amazon ECS Launch Types. This overrides the default launch type stored in your cluster configuration. Type: String Required: No
`--verbose, --debug`	Turn on debug logging. This provides a more verbose command output to aid in diagnosing issues. Required: No
`--region, -r region`	Specifies the AWS Region to use. Defaults to the cluster configured using the configure command. Type: String Required: No
`--cluster-config cluster_config_name`	Specifies the name of the Amazon ECS cluster configuration to use. Defaults to the cluster configuration set as the default. Type: String Required: No
`--ecs-profile ecs_profile`	Specifies the name of the Amazon ECS profile configuration to use. Defaults to the profile configured using the configure profile command. Type: String Required: No
`--aws-profile aws_profile`	Specifies the AWS profile to use. Enables you to use the AWS credentials from an existing named profile in `~/.aws/credentials`. Type: String Required: No
`--cluster, -c cluster_name`	Specifies the Amazon ECS cluster name to use. Defaults to the cluster configured using the configure command. Type: String Required: No
`--empty, -e`	Specifies that an ECS cluster is created with no resources. If other flags are also specified that would create resources, they are ignored and a warning is displayed. Required: No
`--help, -h`	Shows the help text for the specified command. Required: No

Specifying User Data

When launching tasks that use the EC2 launch type, the ECS CLI always creates container instances that include the following user data:


#!/bin/bash
echo ECS_CLUSTER={ clusterName } >> /etc/ecs/ecs.config

This user data directs the container instance to join your ECS cluster. You can optionally include additional user data using the --extra-user-data flag. The flag can be specified multiple times. For example, extra user data can be shell scripts or cloud-init directives. For more information, see Running Commands on Your Linux Instance at Launch in the Amazon EC2 User Guide for Linux Instances.

The Amazon ECS CLI takes the user data and packs it into a MIME multipart archive, which can be used by cloud-init on the container instance. The Amazon ECS CLI allows existing MIME multipart archives to be passed in with --extra-user-data. The Amazon ECS CLI unpacks the existing archive, and then repack it into the final archive (preserving all header and content type information). The following is an example:


ecs-cli up \  
  --capability-iam \  
  --extra-user-data my-shellscript \  
  --extra-user-data my-cloud-boot-hook \  
  --extra-user-data my-mime-multipart-archive \  
  --launch-type EC2

Tagging Resources

The Amazon ECS CLI supports adding metadata in the form of resource tags to your AWS resources. Each tag consists of a key and an optional value. Resource tags can be used for cost allocation, automation, and access control. For more information, see AWS Tagging Strategies.

If you specify resource tags when using the ecs-cli up command, the Amazon ECS cluster as well as the following resources created by the AWS CloudFormation stack can be tagged:

Container instances

Note

In order for your container instances to allow tags, you need to opt in to the new Amazon ECS resource ARN formats. For more information, see Amazon Resource Names (ARNs) and IDs.
VPC
Subnets
Internet gateway
Route tables
Security group
Autoscaling group

Note

For the autoscaling group, the ECS CLI adds a Name tag whose value is the ECS Instance - <CloudFormation stack name>, which is propagated to your container instances. You can override this behavior by specifying your own Name tag.
