Request Syntax

response = client.describe_placement_groups(
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    DryRun=True|False,
    GroupNames=[
        'string',
    ],
    GroupIds=[
        'string',
    ]
)

Parameters:

• Filters (list) –

  The filters.

  • group-name - The name of the placement group.

  • group-arn - The Amazon Resource Name (ARN) of the placement group.

  • spread-level - The spread level for the placement group ( host | rack).

  • state - The state of the placement group ( pending | available | deleting | deleted).

  • strategy - The strategy of the placement group ( cluster | spread | partition).

  • 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 that have a tag with a specific key, regardless of the tag value.

  • (dict) –

    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) –

• DryRun (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.

• GroupNames (list) –

  The names of the placement groups.

  Default: Describes all your placement groups, or only those otherwise specified.

  • (string) –

• GroupIds (list) –

  The IDs of the placement groups.

  • (string) –

Return type:

dict

Returns:
