put-cors-policy¶

Description¶

Sets the cross-origin resource sharing (CORS) configuration on a container so that the container can service cross-origin requests. For example, you might want to enable a request whose origin is http://www.example.com to access your AWS Elemental MediaStore container at my.example.container.com by using the browser’s XMLHttpRequest capability.

To enable CORS on a container, you attach a CORS policy to the container. In the CORS policy, you configure rules that identify origins and the HTTP methods that can be executed on your container. The policy can contain up to 398,000 characters. You can add up to 100 rules to a CORS policy. If more than one rule applies, the service uses the first applicable rule listed.

To learn more about CORS, see Cross-Origin Resource Sharing (CORS) in AWS Elemental MediaStore .

Synopsis¶

  put-cors-policy
--container-name <value>
--cors-policy <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--container-name (string)

The name of the container that you want to assign the CORS policy to.

--cors-policy (list)

The CORS policy to apply to the container.

(structure)

A rule for a CORS policy. You can add up to 100 rules to a CORS policy. If more than one rule applies, the service uses the first applicable rule listed.

AllowedOrigins -> (list)

One or more response headers that you want users to be able to access from their applications (for example, from a JavaScript XMLHttpRequest object).

Each CORS rule must have at least one AllowedOrigins element. The string value can include only one wildcard character (*), for example, http://*.example.com. Additionally, you can specify only one wildcard character to allow cross-origin access for all origins.

(string)

AllowedMethods -> (list)

Identifies an HTTP method that the origin that is specified in the rule is allowed to execute.

Each CORS rule must contain at least one AllowedMethods and one AllowedOrigins element.

(string)

AllowedHeaders -> (list)

Specifies which headers are allowed in a preflight OPTIONS request through the Access-Control-Request-Headers header. Each header name that is specified in Access-Control-Request-Headers must have a corresponding entry in the rule. Only the headers that were requested are sent back.

This element can contain only one wildcard character (*).

(string)

MaxAgeSeconds -> (integer)

The time in seconds that your browser caches the preflight response for the specified resource.

A CORS rule can have only one MaxAgeSeconds element.

ExposeHeaders -> (list)

One or more headers in the response that you want users to be able to access from their applications (for example, from a JavaScript XMLHttpRequest object).

This element is optional for each rule.

(string)

Shorthand Syntax:

AllowedOrigins=string,string,AllowedMethods=string,string,AllowedHeaders=string,string,MaxAgeSeconds=integer,ExposeHeaders=string,string ...

JSON Syntax:

[
  {
    "AllowedOrigins": ["string", ...],
    "AllowedMethods": ["PUT"|"GET"|"DELETE"|"HEAD", ...],
    "AllowedHeaders": ["string", ...],
    "MaxAgeSeconds": integer,
    "ExposeHeaders": ["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¶

Example 1: To add a CORS policy

The following put-cors-policy example adds a cross-origin resource sharing (CORS) policy to the specified container. The contents of the CORS policy are in the file named corsPolicy.json.

aws mediastore put-cors-policy \
    --container-name ExampleContainer \
    --cors-policy file://corsPolicy.json

This command produces no output.

For more information, see Adding a CORS Policy to a Container in the AWS Elemental MediaStore User Guide.

Example 2: To edit a CORS policy

The following put-cors-policy example updates the cross-origin resource sharing (CORS) policy that is assigned to the specified container. The contents of the updated CORS policy are in the file named corsPolicy2.json.

For more information, see Editing a CORS Policy in the AWS Elemental MediaStore User Guide.
