request-certificate

Description

Requests an ACM certificate for use with other Amazon Web Services services. To request an ACM certificate, you must specify a fully qualified domain name (FQDN) in the DomainName parameter. You can also specify additional FQDNs in the SubjectAlternativeNames parameter.

If you are requesting a private certificate, domain validation is not required. If you are requesting a public certificate, each domain name that you specify must be validated to verify that you own or control the domain. You can use DNS validation or email validation . We recommend that you use DNS validation. ACM issues public certificates after receiving approval from the domain owner.

Note

ACM behavior differs from the RFC 6125 specification of the certificate validation process. ACM first checks for a Subject Alternative Name, and, if it finds one, ignores the common name (CN).

After successful completion of the RequestCertificate action, there is a delay of several seconds before you can retrieve information about the new certificate.

Options

--domain-name (string)

Fully qualified domain name (FQDN), such as www.example.com, that you want to secure with an ACM certificate. Use an asterisk (*) to create a wildcard certificate that protects several sites in the same domain. For example, *.example.com protects www.example.com, site.example.com, and images.example.com.

In compliance with RFC 5280 , the length of the domain name (technically, the Common Name) that you provide cannot exceed 64 octets (characters), including periods. To add a longer domain name, specify it in the Subject Alternative Name field, which supports names up to 253 octets in length.

--validation-method (string)

The method you want to use if you are requesting a public certificate to validate that you own or control domain. You can validate with DNS or validate with email . We recommend that you use DNS validation.

Possible values:

  • EMAIL
  • DNS

--subject-alternative-names (list)

Additional FQDNs to be included in the Subject Alternative Name extension of the ACM certificate. For example, add the name www.example.net to a certificate for which the DomainName field is www.example.com if users can reach your site by using either name. The maximum number of domain names that you can add to an ACM certificate is 100. However, the initial quota is 10 domain names. If you need more than 10 names, you must request a quota increase. For more information, see Quotas .

The maximum length of a SAN DNS name is 253 octets. The name is made up of multiple labels separated by periods. No label can be longer than 63 octets. Consider the following examples:

  • (63 octets).(63 octets).(63 octets).(61 octets) is legal because the total length is 253 octets (63+1+63+1+63+1+61) and no label exceeds 63 octets.
  • (64 octets).(63 octets).(63 octets).(61 octets) is not legal because the total length exceeds 253 octets (64+1+63+1+63+1+61) and the first label exceeds 63 octets.
  • (63 octets).(63 octets).(63 octets).(62 octets) is not legal because the total length of the DNS name (63+1+63+1+63+1+62) exceeds 253 octets.

(string)

Syntax:

"string" "string" ...

--idempotency-token (string)

Customer chosen string that can be used to distinguish between calls to RequestCertificate . Idempotency tokens time out after one hour. Therefore, if you call RequestCertificate multiple times with the same idempotency token within one hour, ACM recognizes that you are requesting only one certificate and will issue only one. If you change the idempotency token for each call, ACM recognizes that you are requesting multiple certificates.

--domain-validation-options (list)

The domain name that you want ACM to use to send you emails so that you can validate domain ownership.

(structure)

Contains information about the domain names that you want ACM to use to send you emails that enable you to validate domain ownership.

DomainName -> (string)

A fully qualified domain name (FQDN) in the certificate request.

ValidationDomain -> (string)

The domain name that you want ACM to use to send you validation emails. This domain name is the suffix of the email addresses that you want ACM to use. This must be the same as the DomainName value or a superdomain of the DomainName value. For example, if you request a certificate for testing.example.com , you can specify example.com for this value. In that case, ACM sends domain validation emails to the following five addresses:

Shorthand Syntax:

DomainName=string,ValidationDomain=string ...

JSON Syntax:

[
  {
    "DomainName": "string",
    "ValidationDomain": "string"
  }
  ...
]

--options (structure)

Currently, you can use this parameter to specify whether to add the certificate to a certificate transparency log. Certificate transparency makes it possible to detect SSL/TLS certificates that have been mistakenly or maliciously issued. Certificates that have not been logged typically produce an error message in a browser. For more information, see Opting Out of Certificate Transparency Logging .

CertificateTransparencyLoggingPreference -> (string)

You can opt out of certificate transparency logging by specifying the DISABLED option. Opt in by specifying ENABLED .

Shorthand Syntax:

CertificateTransparencyLoggingPreference=string

JSON Syntax:

{
  "CertificateTransparencyLoggingPreference": "ENABLED"|"DISABLED"
}

--certificate-authority-arn (string)

The Amazon Resource Name (ARN) of the private certificate authority (CA) that will be used to issue the certificate. If you do not provide an ARN and you are trying to request a private certificate, ACM will attempt to issue a public certificate. For more information about private CAs, see the Amazon Web Services Private Certificate Authority user guide. The ARN must have the following form:

arn:aws:acm-pca:region:account:certificate-authority/12345678-1234-1234-1234-123456789012

--tags (list)

One or more resource tags to associate with the certificate.

(structure)

A key-value pair that identifies or specifies metadata about an ACM resource.

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"
  }
  ...
]

--key-algorithm (string)

Specifies the algorithm of the public and private key pair that your certificate uses to encrypt data. RSA is the default key algorithm for ACM certificates. Elliptic Curve Digital Signature Algorithm (ECDSA) keys are smaller, offering security comparable to RSA keys but with greater computing efficiency. However, ECDSA is not supported by all network clients. Some AWS services may require RSA keys, or only support ECDSA keys of a particular size, while others allow the use of either RSA and ECDSA keys to ensure that compatibility is not broken. Check the requirements for the AWS service where you plan to deploy your certificate.

Default: RSA_2048

Possible values:

  • RSA_1024
  • RSA_2048
  • RSA_3072
  • RSA_4096
  • EC_prime256v1
  • EC_secp384r1
  • EC_secp521r1

--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.

Examples

Note

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 request a new ACM certificate

The following request-certificate command requests a new certificate for the www.example.com domain using DNS validation:

aws acm request-certificate --domain-name www.example.com --validation-method DNS

You can enter an idempotency token to distinguish between calls to request-certificate:

aws acm request-certificate --domain-name www.example.com --validation-method DNS --idempotency-token 91adc45q

You can enter one or more subject alternative names to request a certificate that will protect more than one apex domain:

aws acm request-certificate --domain-name example.com --validation-method DNS --idempotency-token 91adc45q --subject-alternative-names www.example.net

You can enter an alternative name that can also be used to reach your website:

aws acm request-certificate --domain-name example.com --validation-method DNS --idempotency-token 91adc45q --subject-alternative-names www.example.com

You can use an asterisk (*) as a wildcard to create a certificate for several subdomains in the same domain:

aws acm request-certificate --domain-name example.com --validation-method DNS --idempotency-token 91adc45q --subject-alternative-names *.example.com

You can also enter multiple alternative names:

aws acm request-certificate --domain-name example.com --validation-method DNS --subject-alternative-names b.example.com c.example.com d.example.com

If you are using email for validation, you can enter domain validation options to specify the domain to which the validation email will be sent:

aws acm request-certificate --domain-name example.com --validation-method EMAIL --subject-alternative-names www.example.com --domain-validation-options DomainName=example.com,ValidationDomain=example.com

The following command opts out of certificate transparency logging when you request a new certificate:

aws acm request-certificate --domain-name www.example.com --validation-method DNS --options CertificateTransparencyLoggingPreference=DISABLED --idempotency-token 184627

Output

CertificateArn -> (string)

String that contains the ARN of the issued certificate. This must be of the form:

arn:aws:acm:us-east-1:123456789012:certificate/12345678-1234-1234-1234-123456789012
