Before you begin: Install and configure AWS CLI. For more information, see Installing and Configuring AWS CLI.

To get information about one or more Availability Zones inside a Region, use the describe-availability-zones command following this syntax:

Request sample
$ aws ec2 describe-availability-zones \
    --profile YOUR_PROFILE \
    --zone-names NOT_SPECIFIED \
    --filters Name=X,Values=Y \
    --endpoint https://fcu.eu-west-2.outscale.com

This command contains the following attributes that you need to specify:

  • (optional) profile: The named profile you want to use, created when configuring AWS CLI. For more information, see Installing and Configuring AWS CLI.

  • (optional) zone-names: The name of one or more Availability Zones.

  • (optional) filters: One or more filters, in the "Name=X,Values=Y" format.

    You can specify several values for a same filter using the "Name=X,Values=Y, Z" format.

    The following filters are available:

    • region-name: The name of the Region where the Availability Zones are located.

    • state: The current state of the Availability Zones ( available | information | impaired | unavailable ).

    • zone-name: The name of the Availability Zones.

  • endpoint: The endpoint corresponding to the Region you want to send the request to. For more information, see Installing and Configuring AWS CLI.

The describe-availability-zones command returns the following elements:

    • State: The current state of the Availability Zone (always available).

    • RegionName: The name of the Region where the Availability Zone is located.

            "ZoneName": "eu-west-2b"
