Synopsis

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

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs. The filters supported by a describe operation are documented with the describe operation. For example:

  • DescribeAvailabilityZones

  • DescribeImages

  • DescribeInstances

  • DescribeKeyPairs

  • DescribeSecurityGroups

  • DescribeSnapshots

  • DescribeSubnets

  • DescribeTags

  • DescribeVolumes

  • DescribeVpcs

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

The filter values. Filter values are case-sensitive.

(string)

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.

(string)

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 | --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 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.

aws ec2 describe-regions \
    --all-regions

Output:

    ]
}

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

Output

Information about the Regions.

(structure)

Describes a Region.

Endpoint -> (string)

The Region service endpoint.
