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 create-load-balancer-listeners , apply-security-groups-to-load-balancer , attach-load-balancer-to-subnets , and add-tags .

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

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 Balancer Guide .

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 Balancer Guide .

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 enable-availability-zones-for-load-balancer .

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 availability-zones .

Syntax:

"string" "string" ...

--security-groups (list)

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

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 Balancer Guide .

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

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

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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

This example creates a load balancer with an HTTPS 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" "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

Output:

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

To create an internal load balancer

This example creates an internal 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" --scheme internal --subnets subnet-a85db0df --security-groups sg-a61988c3

Output:

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