describe-instances

Description

Describes the specified instances or all instances.

If you specify instance IDs, the output includes information for only the specified instances. If you specify filters, the output includes information for only those instances that meet the filter criteria. If you do not specify instance IDs or filters, the output includes information for all instances, which can affect performance. We recommend that you use pagination to ensure that the operation returns quickly and successfully.

If you specify an instance ID that is not valid, an error is returned. If you specify an instance that you do not own, it is not included in the output.

Recently terminated instances might appear in the returned results. This interval is usually less than one hour.

If you describe instances in the rare case where an Availability Zone is experiencing a service disruption and you specify instance IDs that are in the affected zone, or do not specify any instance IDs at all, the call fails. If you describe instances and specify only instance IDs that are in an unaffected zone, the call works normally.

Note

We are retiring EC2-Classic on August 15, 2022. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon EC2 User Guide .

See ‘aws help’ for descriptions of global parameters.

describe-instances 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: Reservations

  • vpc-id - The ID of the VPC that the instance is running in.

(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.

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.

(string)

Shorthand Syntax:

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

JSON Syntax:

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

--instance-ids (list)

The instance IDs.

Default: Describes all your instances.

(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 .

--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.

--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. 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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

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 .

Example 2: To filter for instances with the specified type

The following describe-instances example uses filters to scope the results to instances of the specified type.

aws ec2 describe-instances \
    --filters Name=instance-type,Values=m5.large

For sample of output, see Example 1.

For more information, see Describing instances in a placement group in the Amazon EC2 User Guide.

Example 3: To filter for instances with the specified type and Availability Zone

The following describe-instances example uses multiple filters to scope the results to instances with the specified type that are also in the specified Availability Zone.

aws ec2 describe-instances \
    --filters Name=instance-type,Values=t2.micro,t3.micro Name=availability-zone,Values=us-east-2c

For sample of output, see Example 1.

For more information, see Describing instances in a placement group in the Amazon EC2 User Guide.

Example 4: To filter for instances with the specified type and Availability Zone using a JSON file

The following describe-instances example uses a JSON input file to perform the same filtering as the previous example. When filters get more complicated, they can be easier to specify in a JSON file.

aws ec2 describe-instances \
    --filters file://filters.json

Contents of filters.json:

[
    {
        "Name": "instance-type",
        "Values": ["t2.micro", "t3.micro"]
    },
    {
        "Name": "availability-zone",
        "Values": ["us-east-2c"]
    }
]

For sample of output, see Example 1.

For more information, see Describing instances in a placement group in the Amazon EC2 User Guide.

Example 5: To filter for instances with the specified Owner tag

The following describe-instances example uses tag filters to scope the results to instances that have a tag with the specified tag key (Owner), regardless of the tag value.

aws ec2 describe-instances \
    --filters "Name=tag-key,Values=Owner"

For sample of output, see Example 1.

For more information, see Describing instances in a placement group in the Amazon EC2 User Guide.

Example 6: To filter for instances with the specified my-team tag value

The following describe-instances example uses tag filters to scope the results to instances that have a tag with the specified tag value (my-team), regardless of the tag key.

aws ec2 describe-instances \
    --filters "Name=tag-value,Values=my-team"

For sample of output, see Example 1.

For more information, see Describing instances in a placement group in the Amazon EC2 User Guide.

Example 7: To filter for instances with the specified Owner tag and my-team value

The following describe-instances example uses tag filters to scope the results to instances that have the specified tag (Owner=my-team).

aws ec2 describe-instances \
    --filters "Name=tag:Owner,Values=my-team"

For sample of output, see Example 1.

For more information, see Describing instances in a placement group in the Amazon EC2 User Guide.

Example 8: To display only instance and subnet IDs for all instances

The following describe-instances examples use the --query parameter to display only the instance and subnet IDs for all instances, in JSON format.

Linux and macOS:

aws ec2 describe-instances \
    --query 'Reservations[*].Instances[*].{Instance:InstanceId,Subnet:SubnetId}' \
    --output json

Windows:

aws ec2 describe-instances ^
    --query "Reservations[*].Instances[*].{Instance:InstanceId,Subnet:SubnetId}" ^
    --output json

Output:
