[ aws . apprunner ]



Associate your own domain name with the App Runner subdomain URL of your App Runner service.

After you call AssociateCustomDomain and receive a successful response, use the information in the CustomDomain record that's returned to add CNAME records to your Domain Name System (DNS). For each mapped domain name, add a mapping to the target App Runner subdomain and one or more certificate validation records. App Runner then performs DNS validation to verify that you own or control the domain name that you associated. App Runner tracks domain validity in a certificate stored in AWS Certificate Manager (ACM) .

--service-arn (string)

The Amazon Resource Name (ARN) of the App Runner service that you want to associate a custom domain name with.

--domain-name (string)

A custom domain endpoint to associate. Specify a root domain (for example, ), a subdomain (for example, or ), or a wildcard (for example, * ).

--enable-www-subdomain | --no-enable-www-subdomain (boolean)

Set to true to associate the subdomain ``www.*DomainName* `` with the App Runner service in addition to the base domain.

Default: true

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To associate a domain name and the www subdomain with a service

The following associate-custom-domain example associates a custom domain name that you control with an App Runner service. The domain name is the root domain, including the special-case subdomain
