Set up to use Amazon ECS - Amazon Elastic Container Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Set up to use Amazon ECS

If you've already signed up for Amazon Web Services (Amazon) and have been using Amazon Elastic Compute Cloud (Amazon EC2), you are close to being able to use Amazon ECS. The set-up process for the two services is similar. The following guide prepares you for launching your first Amazon ECS cluster.

Complete the following tasks to get set up for Amazon ECS.

Sign up for an Amazon Web Services account

If you do not have an Amazon Web Services account, use the following procedure to create one.

To sign up for Amazon Web Services
  1. Open http://www.amazonaws.cn/ and choose Sign Up.

  2. Follow the on-screen instructions.

Amazon sends you a confirmation email after the sign-up process is complete. At any time, you can view your current account activity and manage your account by going to http://www.amazonaws.cn/ and choosing My Account.

Secure IAM users

After you sign up for an Amazon Web Services account, safeguard your administrative user by turning on multi-factor authentication (MFA). For instructions, see Enable a virtual MFA device for an IAM user (console) in the IAM User Guide.

To give other users access to your Amazon Web Services account resources, create IAM users. To secure your IAM users, turn on MFA and only give the IAM users the permissions needed to perform their tasks.

For more information about creating and securing IAM users, see the following topics in the IAM User Guide:

Create a virtual private cloud

You can use Amazon Virtual Private Cloud (Amazon VPC) to launch Amazon resources into a virtual network that you've defined. We strongly suggest that you launch your container instances in a VPC.

If you have a default VPC, you can skip this section and move to the next task, Create a security group. To determine whether you have a default VPC, see Supported Platforms in the Amazon EC2 Console in the Amazon EC2 User Guide for Linux Instances. Otherwise, you can create a nondefault VPC in your account using the steps below.

Important

If your account supports Amazon EC2 Classic in a region, then you do not have a default VPC in that region.

For information about how to create a VPC, see Create a VPC only in the Amazon VPC User Guide, and use the following table to determine what options to select.

Option Value

Resources to create

VPC only
Name

Optionally provide a name for your VPC.

IPv4 CIDR block

IPv4 CIDR manual input

The CIDR block size must have a size between /16 and /28.

IPv6 CIDR block

No IPv6 CIDR block

Tenancy

Default

For more information about Amazon VPC, see What is Amazon VPC? in the Amazon VPC User Guide.

Create a security group

Security groups act as a firewall for associated container instances, controlling both inbound and outbound traffic at the container instance level. You can add rules to a security group that enable you to connect to your container instance from your IP address using SSH. You can also add rules that allow inbound and outbound HTTP and HTTPS access from anywhere. Add any rules to open ports that are required by your tasks. Container instances require external network access to communicate with the Amazon ECS service endpoint.

If you plan to launch container instances in multiple Regions, you need to create a security group in each Region. For more information, see Regions and Availability Zones in the Amazon EC2 User Guide for Linux Instances.

Tip

You need the public IP address of your local computer, which you can get using a service. For example, we provide the following service: http://checkip.amazonaws.com/ or https://checkip.amazonaws.com/. To locate another service that provides your IP address, use the search phrase "what is my IP address." If you are connecting through an internet service provider (ISP) or from behind a firewall without a static IP address, you must find out the range of IP addresses used by client computers.

For information about how to create a security group, see Create a security group in the Amazon EC2 User Guide for Linux Instances and use the following table to determine what options to select.

Option Value

Region

The same Region in which you created your key pair.
Name A name that is easy for you to remember, such as ecs-instances-default-cluster.
VPC The default VPC (marked with "(default)" .
Note

If your account supports Amazon EC2 Classic, select the VPC that you created in the previous task.

For information about the outbound rules to add for your use cases, see Security group rules for different use cases in the Amazon EC2 User Guide for Linux Instances.

Amazon ECS container instances do not require any inbound ports to be open. However, you might want to add an SSH rule so you can log into the container instance and examine the tasks with Docker commands. You can also add rules for HTTP and HTTPS if you want your container instance to host a task that runs a web server. Container instances do require external network access to communicate with the Amazon ECS service endpoint. Complete the following steps to add these optional security group rules.

Add the following three inbound rules to your security group.For information about how to create a security group, see Add rules to your security group in the Amazon EC2 User Guide for Linux Instances.

Option Value

HTTP rule

Type: HTTP

Source: Anywhere (0.0.0.0/0)

This option automatically adds the 0.0.0.0/0 IPv4 CIDR block as the source. This is acceptable for a short time in a test environment, but it's unsafe in production environments. In production, authorize only a specific IP address or range of addresses to access your instance.

HTTPS rule

Type: HTTPS

Source: Anywhere (0.0.0.0/0)

This is acceptable for a short time in a test environment, but it's unsafe in production environments. In production, authorize only a specific IP address or range of addresses to access your instance.

SSH rule

Type: SSH

Source: Custom, specify the public IP address of your computer or network in CIDR notation. To specify an individual IP address in CIDR notation, add the routing prefix /32. For example, if your IP address is 203.0.113.25, specify 203.0.113.25/32. If your company allocates addresses from a range, specify the entire range, such as 203.0.113.0/24.

Important

For security reasons, we don't recommend that you allow SSH access from all IP addresses (0.0.0.0/0) to your instance, except for testing purposes and only for a short time.

Create the credentials to connect to your EC2 instance

For Amazon ECS, a key pair is only needed if you intend on using the EC2 launch type.

A Linux instance, such as an Amazon ECS container instance, has no password to use for SSH access. You use a key pair to log in to your instance securely. You specify the name of the key pair when you launch your container instance, then provide the private key when you log in using SSH.

If you haven't created a key pair already, you can create one using the Amazon EC2 console. If you plan to launch instances in multiple regions, you'll need to create a key pair in each region. For more information about regions, see Regions and Availability Zones in the Amazon EC2 User Guide for Linux Instances.

To create a key pair
  • Use the Amazon EC2 console to create a key pair. For more information about creating a key pair, see Create a key pair in the Amazon EC2 User Guide for Linux Instances.

For information about how to connect to your instance, see Connect to your Linux instance in the Amazon EC2 User Guide for Linux Instances.

Install the Amazon CLI

The Amazon Web Services Management Console can be used to manage all operations manually with Amazon ECS. However, you can install the Amazon CLI on your local desktop or a developer box so that you can build scripts that can automate common management tasks in Amazon ECS.

To use the Amazon CLI with Amazon ECS, install the latest Amazon CLI version. For information about installing the Amazon CLI or upgrading it to the latest version, see Installing the Amazon Command Line Interface in the Amazon Command Line Interface User Guide.
