See 'aws help' for descriptions of global parameters.

Synopsis

  describe-regions
[--filters <value>]
[--region-names <value>]
[--dry-run | --no-dry-run]
[--all-regions | --no-all-regions]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--filters (list)

The filters.

  • endpoint - The endpoint of the Region (for example, ec2.us-east-1.amazonaws.com ).
  • opt-in-status - The opt-in status of the Region (opt-in-not-required | opted-in | not-opted-in ).
  • region-name - The name of the Region (for example, us-east-1 ).

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--region-names (list)

The names of the Regions. You can specify any Regions, whether they are enabled and disabled for your account.

Syntax:

"string" "string" ...

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--all-regions | --no-all-regions (boolean)

Indicates whether to display all Regions, including Regions that are disabled for your account.

--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.

See 'aws help' for descriptions of global parameters.

Examples

Example 1: To describe all of your enabled Regions

The following describe-regions example describes all of the Regions that are enabled for your account.

aws ec2 describe-regions

Output:

{
    "Regions": [
        {
            "Endpoint": "ec2.eu-north-1.amazonaws.com",

Example 2: To describe enabled Regions with an endpoint whose name contains a specific string

The following describe-regions example describes all Regions that you have enabled that have the string "us" in the endpoint.

aws ec2 describe-regions --filters "Name=endpoint,Values=*us*"

Output:

{
    "Regions": [
        {
            "Endpoint": "ec2.us-east-1.amazonaws.com",
            "RegionName": "us-east-1"
        },
        {
            "Endpoint": "ec2.us-east-2.amazonaws.com",
            "RegionName": "us-east-2"
        },
        {
            "Endpoint": "ec2.us-west-1.amazonaws.com",
            "RegionName": "us-west-1"
        },
        {

            "RegionName": "us-west-2"
        },
    ]
}

To describe all Regions

The following describe-regions example describes all available Regions, including opt-in Regions like HKG and BAH. For a description of opt-in Regions, see Available Regions in the Amazon EC2 User Guide.

    --all-regions

To list the Region names only

The following describe-regions example uses the --query parameter to filter the output and return only the names of the Regions as text.

aws ec2 describe-regions \
    --all-regions \
    --query "Regions[].{Name:RegionName}" \
    --output text

Output:

eu-north-1
ap-south-1
eu-west-3
eu-west-2
eu-west-1
ap-northeast-3
ap-northeast-2
me-south-1
ap-northeast-1
sa-east-1
ca-central-1
ap-east-1
ap-southeast-1
ap-southeast-2
eu-central-1
us-east-1
us-east-2
us-west-1
us-west-2
