system-status-ok

Description

Wait until JMESPath query InstanceStatuses[].SystemStatus.Status returns ok for all elements when polling with describe-instance-status. 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.

See ‘aws help’ for descriptions of global parameters.

system-status-ok 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: InstanceStatuses

Options

--filters (list)

The filters.

  • availability-zone - The Availability Zone of the instance.

  • event.code - The code for the scheduled event (instance-reboot | system-reboot | system-maintenance | instance-retirement | instance-stop ).

  • event.description - A description of the event.

  • event.instance-event-id - The ID of the event whose date and time you are modifying.

  • event.not-after - The latest end time for the scheduled event (for example, 2014-09-15T17:15:20.000Z ).

  • event.not-before - The earliest start time for the scheduled event (for example, 2014-09-15T17:15:20.000Z ).

  • event.not-before-deadline - The deadline for starting the event (for example, 2014-09-15T17:15:20.000Z ).

  • instance-state-code - The code for the instance state, as a 16-bit unsigned integer. The high byte is used for internal purposes and should be ignored. The low byte is set based on the state represented. The valid values are 0 (pending), 16 (running), 32 (shutting-down), 48 (terminated), 64 (stopping), and 80 (stopped).

  • instance-state-name - The state of the instance (pending | running | shutting-down | terminated | stopping | stopped ).

  • instance-status.reachability - Filters on instance status where the name is reachability (passed | failed | initializing | insufficient-data ).

  • instance-status.status - The status of the instance (ok | impaired | initializing | insufficient-data | not-applicable ).

  • system-status.reachability - Filters on system status where the name is reachability (passed | failed | initializing | insufficient-data ).

  • system-status.status - The system status of the instance (ok | impaired | initializing | insufficient-data | not-applicable ).

(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", ...]
  }
  ...
]

--instance-ids (list)

The instance IDs.

Default: Describes all your instances.

Constraints: Maximum 100 explicitly specified instance IDs.

(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 .

--include-all-instances | --no-include-all-instances (boolean)

When true , includes the health status for all instances. When false , includes the health status for running instances only.

Default: false

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To wait until the system status is OK

The following wait system-status-ok example command pauses and resumes running only after it confirms that the system status of the specified instance is OK. It produces no output.

aws ec2 wait system-status-ok \
    --instance-ids i-1234567890abcdef0

Output

None
