create-listener

Description

Creates a listener for the specified Application Load Balancer or Network Load Balancer.

To update a listener, use ModifyListener . When you are finished with a listener, you can delete it using DeleteListener . If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer .

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.

For more information, see Listeners for Your Application Load Balancers in the Application Load Balancers Guide and Listeners for Your Network Load Balancers in the Network Load Balancers Guide .

Options

--load-balancer-arn (string)

The Amazon Resource Name (ARN) of the load balancer.

--protocol (string)

The protocol for connections from clients to the load balancer. For Application Load Balancers, the supported protocols are HTTP and HTTPS. For Network Load Balancers, the supported protocol is TCP.

Possible values:

  • HTTP
  • HTTPS
  • TCP

--port (integer)

The port on which the load balancer is listening.

--ssl-policy (string)

[HTTPS listeners] The security policy that defines which ciphers and protocols are supported. The default is the current predefined security policy.

--certificates (list)

[HTTPS listeners] The default SSL server certificate. You must provide exactly one default certificate. To create a certificate list, use AddListenerCertificates .

Shorthand Syntax:

CertificateArn=string,IsDefault=boolean ...

JSON Syntax:

[
  {
    "CertificateArn": "string",
    "IsDefault": true|false
  }
  ...
]

--default-actions (list)

The actions for the default rule. The rule must include one forward action or one or more fixed-response actions.

If the action type is forward , you can specify a single target group. The protocol of the target group must be HTTP or HTTPS for an Application Load Balancer or TCP for a Network Load Balancer.

[HTTPS listener] If the action type is authenticate-oidc , you can use an identity provider that is OpenID Connect (OIDC) compliant to authenticate users as they access your application.

[HTTPS listener] If the action type is authenticate-cognito , you can use Amazon Cognito to authenticate users as they access your application.

[Application Load Balancer] If the action type is redirect , you can redirect HTTP and HTTPS requests.

[Application Load Balancer] If the action type is fixed-response , you can return a custom HTTP response.

Shorthand Syntax:

Type=string,TargetGroupArn=string,AuthenticateOidcConfig={Issuer=string,AuthorizationEndpoint=string,TokenEndpoint=string,UserInfoEndpoint=string,ClientId=string,ClientSecret=string,SessionCookieName=string,Scope=string,SessionTimeout=long,AuthenticationRequestExtraParams={KeyName1=string,KeyName2=string},OnUnauthenticatedRequest=string},AuthenticateCognitoConfig={UserPoolArn=string,UserPoolClientId=string,UserPoolDomain=string,SessionCookieName=string,Scope=string,SessionTimeout=long,AuthenticationRequestExtraParams={KeyName1=string,KeyName2=string},OnUnauthenticatedRequest=string},Order=integer,RedirectConfig={Protocol=string,Port=string,Host=string,Path=string,Query=string,StatusCode=string},FixedResponseConfig={MessageBody=string,StatusCode=string,ContentType=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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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 listener

This example creates an HTTP listener for the specified Application Load Balancer that forwards requests to the specified target group.

Command:

aws elbv2 create-listener --load-balancer-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188 --protocol HTTP --port 80 --default-actions Type=forward,TargetGroupArn=arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067

Output:

{
  "Listeners": [
      {
          "Protocol": "HTTP",
          "Port": 80,
          "DefaultActions": [
              {
                  "TargetGroupArn": "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067",

To create an HTTPS listener

This example creates an HTTPS listener for the specified Application Load Balancer that forwards requests to the specified target group. Note that you must specify an SSL certificate for an HTTPS listener. You can create and manage certificates using AWS Certificate Manager (ACM). Alternatively, you can create a certificate using SSL/TLS tools, get the certificate signed by a certificate authority (CA), and upload the certificate to AWS Identity and Access Management (IAM).

Command:

aws elbv2 create-listener --load-balancer-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188 --protocol HTTPS --port 443 --certificates CertificateArn=arn:aws:acm:us-west-2:123456789012:certificate/3dcb0a41-bd72-4774-9ad9-756919c40557 --ssl-policy ELBSecurityPolicy-2016-08 --default-actions Type=forward,TargetGroupArn=arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067
