describe-ec2-instance-limits

Description

Retrieves the instance limits and current utilization for an Amazon Web Services Region or location. Instance limits control the number of instances, per instance type, per location, that your Amazon Web Services account can use. Learn more at Amazon EC2 Instance Types . The information returned includes the maximum number of instances allowed and your account’s current usage across all fleets. This information can affect your ability to scale your GameLift fleets. You can request a limit increase for your account by using the Service limits page in the GameLift console.

Instance limits differ based on whether the instances are deployed in a fleet’s home Region or in a remote location. For remote locations, limits also differ based on the combination of home Region and remote location. All requests must specify an Amazon Web Services Region (either explicitly or as your default settings). To get the limit for a remote location, you must also specify the location. For example, the following requests all return different results:

• Request specifies the Region ap-northeast-1 with no location. The result is limits and usage data on all instance types that are deployed in us-east-2 , by all of the fleets that reside in ap-northeast-1 .

• Request specifies the Region us-east-1 with location ca-central-1 . The result is limits and usage data on all instance types that are deployed in ca-central-1 , by all of the fleets that reside in us-east-2 . These limits do not affect fleets in any other Regions that deploy instances to ca-central-1 .

• Request specifies the Region eu-west-1 with location ca-central-1 . The result is limits and usage data on all instance types that are deployed in ca-central-1 , by all of the fleets that reside in eu-west-1 .

This operation can be used in the following ways:

• To get limit and usage data for all instance types that are deployed in an Amazon Web Services Region by fleets that reside in the same Region: Specify the Region only. Optionally, specify a single instance type to retrieve information for.

• To get limit and usage data for all instance types that are deployed to a remote location by fleets that reside in different Amazon Web Services Region: Provide both the Amazon Web Services Region and the remote location. Optionally, specify a single instance type to retrieve information for.

If successful, an EC2InstanceLimits object is returned with limits and usage data for each requested instance type.

Options

--ec2-instance-type (string)

Name of an Amazon EC2 instance type that is supported in GameLift. A fleet instance type determines the computing resources of each instance in the fleet, including CPU, memory, storage, and networking capacity. Do not specify a value for this parameter to retrieve limits for all instance types.

--location (string)

The name of a remote location to request instance limits for, in the form of an Amazon Web Services Region code such as us-west-2 .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

To retrieve service limits for an EC2 instance type

The following describe-ec2-instance-limits example displays the maximum allowed instances and current instances in use for the specified EC2 instance type in the current Region. The result indicates that only five of the allowed twenty instances are being used.

aws gamelift describe-ec2-instance-limits \
    --ec2-instance-type m5.large

Output:

{
    "EC2InstanceLimits": [
        {
            "EC2InstanceType": ""m5.large",
            "CurrentInstances": 5,
            "InstanceLimit": 20
        }
    ]
}

For more information, see Choose Computing Resources in the Amazon GameLift Developer Guide.

Output

EC2InstanceLimits -> (list)

The maximum number of instances for the specified instance type.

(structure)

The GameLift service limits for an Amazon EC2 instance type and current utilization. GameLift allows Amazon Web Services accounts a maximum number of instances, per instance type, per Amazon Web Services Region or location, for use with GameLift. You can request an limit increase for your account by using the Service limits page in the GameLift console.
