create-load-balancer

Description

Creates a Classic Load Balancer.

You can add listeners, security groups, subnets, and tags when you create your load balancer, or you can add them later using CreateLoadBalancerListeners , ApplySecurityGroupsToLoadBalancer , AttachLoadBalancerToSubnets , and AddTags .

To describe your current load balancers, see DescribeLoadBalancers . When you are finished with a load balancer, you can delete it using DeleteLoadBalancer .

You can create up to 20 load balancers per region per account. You can request an increase for the number of load balancers for your account. For more information, see Limits for Your Classic Load Balancer in the Classic Load Balancers Guide .

See ‘aws help’ for descriptions of global parameters.

Options

--load-balancer-name (string)

The name of the load balancer.

This name must be unique within your set of load balancers for the region, must have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and cannot begin or end with a hyphen.

--listeners (list)

The listeners.

For more information, see Listeners for Your Classic Load Balancer in the Classic Load Balancers Guide .

(structure)

Information about a listener.

For information about the protocols and the ports supported by Elastic Load Balancing, see Listeners for Your Classic Load Balancer in the Classic Load Balancers Guide .

Protocol -> (string)

The load balancer transport protocol to use for routing: HTTP, HTTPS, TCP, or SSL.

LoadBalancerPort -> (integer)

The port on which the load balancer is listening. On EC2-VPC, you can specify any port from the range 1-65535. On EC2-Classic, you can specify any port from the following list: 25, 80, 443, 465, 587, 1024-65535.

InstanceProtocol -> (string)

The protocol to use for routing traffic to instances: HTTP, HTTPS, TCP, or SSL.

If the front-end protocol is HTTP, HTTPS, TCP, or SSL, InstanceProtocol must be at the same protocol.

If there is another listener with the same InstancePort whose InstanceProtocol is secure, (HTTPS or SSL), the listener’s InstanceProtocol must also be secure.

If there is another listener with the same InstancePort whose InstanceProtocol is HTTP or TCP, the listener’s InstanceProtocol must be HTTP or TCP.

InstancePort -> (integer)

The port on which the instance is listening.

SSLCertificateId -> (string)

The Amazon Resource Name (ARN) of the server certificate.

Shorthand Syntax:

Protocol=string,LoadBalancerPort=integer,InstanceProtocol=string,InstancePort=integer,SSLCertificateId=string ...

JSON Syntax:

[
  {
    "Protocol": "string",
    "LoadBalancerPort": integer,
    "InstanceProtocol": "string",
    "InstancePort": integer,
    "SSLCertificateId": "string"
  }
  ...
]

--availability-zones (list)

One or more Availability Zones from the same region as the load balancer.

You must specify at least one Availability Zone.

You can add more Availability Zones after you create the load balancer using EnableAvailabilityZonesForLoadBalancer .

(string)

Syntax:

"string" "string" ...

--subnets (list)

The IDs of the subnets in your VPC to attach to the load balancer. Specify one subnet per Availability Zone specified in AvailabilityZones .

(string)

Syntax:

"string" "string" ...

--security-groups (list)

The IDs of the security groups to assign to the load balancer.

(string)

Syntax:

"string" "string" ...

--scheme (string)

The type of a load balancer. Valid only for load balancers in a VPC.

By default, Elastic Load Balancing creates an Internet-facing load balancer with a DNS name that resolves to public IP addresses. For more information about Internet-facing and Internal load balancers, see Load Balancer Scheme in the Elastic Load Balancing User Guide .

Specify internal to create a load balancer with a DNS name that resolves to private IP addresses.

--tags (list)

A list of tags to assign to the load balancer.

For more information about tagging your load balancer, see Tag Your Classic Load Balancer in the Classic Load Balancers Guide .

(structure)

Information about a tag.

Key -> (string)

The key of the tag.

Value -> (string)

The value of the tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To create an HTTP load balancer

This example creates a load balancer with an HTTP listener in a VPC.

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" --subnets subnet-15aaab61 --security-groups sg-a61988c3

Output:

{
    "DNSName": "my-load-balancer-1234567890.us-west-2.elb.amazonaws.com"
}

This example creates a load balancer with an HTTP listener in EC2-Classic.

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" --availability-zones us-west-2a us-west-2b

Output:

{
    "DNSName": "my-load-balancer-123456789.us-west-2.elb.amazonaws.com"
}

To create an HTTPS load balancer

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" "Protocol=HTTPS,LoadBalancerPort=443,InstanceProtocol=HTTP,InstancePort=80,SSLCertificateId=arn:aws:iam::123456789012:server-certificate/my-server-cert" --subnets subnet-15aaab61 --security-groups sg-a61988c3

Output:

{
    "DNSName": "my-load-balancer-1234567890.us-west-2.elb.amazonaws.com"
}

This example creates a load balancer with an HTTPS listener in EC2-Classic.

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" "Protocol=HTTPS,LoadBalancerPort=443,InstanceProtocol=HTTP,InstancePort=80,SSLCertificateId=arn:aws:iam::123456789012:server-certificate/my-server-cert" --availability-zones us-west-2a us-west-2b

{
    "DNSName": "my-load-balancer-123456789.us-west-2.elb.amazonaws.com"

Command:

aws elb create-load-balancer --load-balancer-name my-load-balancer --listeners "Protocol=HTTP,LoadBalancerPort=80,InstanceProtocol=HTTP,InstancePort=80" --scheme internal --subnets subnet-a85db0df --security-groups sg-a61988c3

Output:

{
    "DNSName": "internal-my-load-balancer-123456789.us-west-2.elb.amazonaws.com"

DNSName -> (string)

The DNS name of the load balancer.
