[ aws . ec2 . wait ]



Wait until JMESPath query Subnets[].State returns available for all elements when polling with describe-subnets. It will poll every 15 seconds until a successful state has been reached. This will exit with a return code of 255 after 40 failed checks.

subnet-available is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Subnets

--filters (list)

The filters.

  • availability-zone - The Availability Zone for the subnet. You can also use availabilityZone as the filter name.
  • availability-zone-id - The ID of the Availability Zone for the subnet. You can also use availabilityZoneId as the filter name.
  • available-ip-address-count - The number of IPv4 addresses in the subnet that are available.
  • cidr-block - The IPv4 CIDR block of the subnet. The CIDR block you specify must exactly match the subnet's CIDR block for information to be returned for the subnet. You can also use cidr or cidrBlock as the filter names.
  • customer-owned-ipv4-pool - The customer-owned IPv4 address pool associated with the subnet.
  • default-for-az - Indicates whether this is the default subnet for the Availability Zone (true | false ). You can also use defaultForAz as the filter name.
  • enable-dns64 - Indicates whether DNS queries made to the Amazon-provided DNS Resolver in this subnet should return synthetic IPv6 addresses for IPv4-only destinations.
  • enable-lni-at-device-index - Indicates the device position for local network interfaces in this subnet. For example, 1 indicates local network interfaces in this subnet are the secondary network interface (eth1).
  • ipv6-cidr-block-association.ipv6-cidr-block - An IPv6 CIDR block associated with the subnet.
  • ipv6-cidr-block-association.association-id - An association ID for an IPv6 CIDR block associated with the subnet.
  • ipv6-cidr-block-association.state - The state of an IPv6 CIDR block associated with the subnet.
  • ipv6-native - Indicates whether this is an IPv6 only subnet (true | false ).
  • map-customer-owned-ip-on-launch - Indicates whether a network interface created in this subnet (including a network interface created by RunInstances ) receives a customer-owned IPv4 address.
  • map-public-ip-on-launch - Indicates whether instances launched in this subnet receive a public IPv4 address.
  • outpost-arn - The Amazon Resource Name (ARN) of the Outpost.
  • owner-id - The ID of the Amazon Web Services account that owns the subnet.
  • private-dns-name-options-on-launch.hostname-type - The type of hostname to assign to instances in the subnet at launch. For IPv4-only and dual-stack (IPv4 and IPv6) subnets, an instance DNS name can be based on the instance IPv4 address (ip-name) or the instance ID (resource-name). For IPv6 only subnets, an instance DNS name must be based on the instance ID (resource-name).
  • private-dns-name-options-on-launch.enable-resource-name-dns-a-record - Indicates whether to respond to DNS queries for instance hostnames with DNS A records.
  • private-dns-name-options-on-launch.enable-resource-name-dns-aaaa-record - Indicates whether to respond to DNS queries for instance hostnames with DNS AAAA records.
  • state - The state of the subnet (pending | available ).
  • subnet-arn - The Amazon Resource Name (ARN) of the subnet.
  • subnet-id - The ID of the subnet.
  • tag :<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA , specify tag:Owner for the filter name and TeamA for the filter value.
  • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.
  • vpc-id - The ID of the VPC for the subnet.


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.

If you specify multiple filters, the filters are joined with an AND , and the request returns only results that match all of the specified filters.

Name -> (string)

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

Values -> (list)

The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR , and the request returns all results that match any of the specified values.


Shorthand Syntax:

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

JSON Syntax:

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

--subnet-ids (list)

The IDs of the subnets.

Default: Describes all your subnets.



"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 .

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.



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 wait until a subnet is available

The following wait subnet-available example pauses and resumes running only after it confirms that the specified subnet is available. It produces no output.
