list-virtual-clusters

Description

Lists information about the specified virtual cluster. Virtual cluster is a managed entity on Amazon EMR on EKS. You can create, describe, list and delete virtual clusters. They do not consume any additional resource in your system. A single virtual cluster maps to a single Kubernetes namespace. Given this relationship, you can model virtual clusters the same way you model Kubernetes namespaces to meet your requirements.

See ‘aws help’ for descriptions of global parameters.

list-virtual-clusters 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: virtualClusters

Synopsis

[--container-provider-id <value>]
[--container-provider-type <value>]
[--created-after <value>]
[--created-before <value>]
[--states <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--container-provider-id (string)

The container provider ID of the virtual cluster.

--container-provider-type (string)

The container provider type of the virtual cluster. EKS is the only supported type as of now.

Possible values:

• EKS

--created-after (timestamp)

The date and time after which the virtual clusters are created.

--created-before (timestamp)

The date and time before which the virtual clusters are created.

--states (list)

The states of the requested virtual clusters.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  RUNNING
  TERMINATING
  TERMINATED
  ARRESTED

--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.

Output

virtualClusters -> (list)

This output lists the specified virtual clusters.

(structure)

This entity describes a virtual cluster. A virtual cluster is a Kubernetes namespace that Amazon EMR is registered with. Amazon EMR uses virtual clusters to run jobs and host endpoints. Multiple virtual clusters can be backed by the same physical cluster. However, each virtual cluster maps to one namespace on an EKS cluster. Virtual clusters do not create any active resources that contribute to your bill or that require lifecycle management outside the service.

id -> (string)

The ID of the virtual cluster.

name -> (string)

The name of the virtual cluster.

arn -> (string)

The ARN of the virtual cluster.

state -> (string)

The state of the virtual cluster.

containerProvider -> (structure)

The container provider of the virtual cluster.

type -> (string)

The type of the container provider. EKS is the only supported type as of now.

id -> (string)

The ID of the container cluster.

info -> (structure)

The information about the container cluster.

eksInfo -> (structure)

The information about the EKS cluster.

namespace -> (string)

The namespaces of the EKS cluster.

createdAt -> (timestamp)

The date and time when the virtual cluster is created.

tags -> (map)

The assigned tags of the virtual cluster.

key -> (string)

value -> (string)

nextToken -> (string)

This output displays the token for the next set of virtual clusters.
